Повний текст джерелаThis thesis presents a unique model of the SGAM (Smart Grid Architecture Model) with considering the state of the art of the different research directions of the smart grid and. The hybrid marine-hydrogen active power generation system has been modeled to represent the component layer of the SGAM. The system integrates the MW scale PEM electrolyzer and fuel cell systems as the main energy balance components. The LiFePO4 battery is used to cover the fast dynamics of the electrical energy. Moreover, the thesis analyzes the centralized and the decentralized energy management system. The MAS (Multi-Agent Systems) represents the paradigm of the decentralized system. The JADE platform is used to develop the MAS due to its general domain of application, open source and free license software, interface with MATLAB and the computability with the FIPA (Foundation of Intelligent Physical Agent) standards. The JADE based energy management system balances the energy between the generation (marine-current energy conversion system) and the demand side (residential load profile) during the stand-alone and the grid-connected modes of operation. The proposed model of the SGAM can be considered as a pilot case study that enables the detailed analysis and the applications of the different smart grid research directions

Повний текст джерелаEtt smart nät är ett energinätverk som hanterar energigenerering och distributionmer effektivt efter slutanvändarnas energikrav i realtid genom kontrolloch kommunikationsteknik. Genom att distribuera smarta nät kan du förbättraenergieffektiviteten, förbättra nätverk säkerheten och minska kostnadernaför både energileverantören och slutanvändarna. Men dessa fördelar kommermed privata utmaningar. En av dessa utmaningar är problemet med smartamätare. I ett smart nät används den smarta mätaren för att registrera energitillförselni realtid och att återkoppla mätningarna till energileverantören.Eftersom energinlevereras efter begäran, innehåller dessa smarta mätarregisterinformationen om slutanvändarens energibehovs profil och därmed riskerardet att äventyra konsumenternas privatliv. När det gäller denna fråga kanen uppladdningsbar energilagring användas för att minska denna risk genomatt förändra konsumenternas energiförbruknings profil. Förbättringen av privatkommerdock att leda till att konsumenternas kostnad för inköp av energiökar, vilket strider mot den ursprungliga kostnads besparande motivationen förkonsumenterna. I detta arbete undersöker vi utformningen av en privatliv höjandeoch kostnads effektiv energihanterings strategi. I detalj antas dynamiskprissättning av energi så att konsumenten har möjlighet att utnyttja energilagringför att minska sin energikostnad. Vidare används Kullback-Leiblerdivergensvärde som privatliv metrisk, och den förväntade kostnads besparingsvärde utvärderas också. För att studera avvägningen mellan privatliv och kostnadär den föreslagna objektiv funktionen en viktad summa av Kullback-Leiblerdivergensvärde och förvÃďntad kostnads besparings värde. Vi bryter först itubåde Kullback-Leibler-divergens värde och den förväntade kostnads besparingeni additativa former över en finit horisont. Baserat på de fördefinierade antagandenauttrycker vi den övergripande objektiva funktionen med state-action-paroch omformulerar energistyrnings designen i en Markov-beslutsprocess (MDP),och den finita optimala lösningen kan erhållas genom att använda dynamiskBellman-programmering. Slutligen, i det speciella fallet med oberoende ochidentiskt distribuerad (i.i.d) efterfrågan karakteriserar vi uttryckligen en stationärpolitik för den oändliga horisontens genomsnittliga kostnad genom attvisa att denna policy kan bevara en viss invariant egenskap hos trosuppfattningen.Vi visar också att man med den här stationära principen kan uppnå ettoptimalt privatliv läckagevärde.

Повний текст джерелаThis thesis is motivated by the electric power system transformations due to more renewable integration and changing consumption patterns. Energy storage is one possible solution to facilitate a smooth transition, ensuring the stability of the power system. In this thesis Li-Ion battery is used both at the level of individual consumers, minimizing the cost of electricity by performing energy arbitrage under time-varying electricity price, power factor correction, peak demand shaving and energy backup, and at the grid level for increasing reliability and stability of the power network by performing dynamic regulation and phase balancing. The cost of the batteries being still high, the importance is also given to the health of the battery taking into account its degradation in optimization and control formulations. Several case studies using real data are conducted to evaluate the performance of the storage control and optimization algorithms. We observe that the ever-decreasing prices of batteries and the growing share of intermittent renewables will only increase the relevance of this work for future power networks

Повний текст джерелаPower grids are designed to work under balanced supply and demand at all times. This hard constraint is increasingly challenged by the introduction of higher shares of intermittent renewable generation in the energy generation portfolios of our nations. The Smart Grid paradigm offers to shift part of this problem from the generation to the demand side, reducing the need for polluting, and expensive, peak power plants. Through the usage of demand response programs, energy storage systems and distributed generation sources, the Smart Grid can cope with demand-generation variability leveraging a portfolio of distributed flexibility assets. The main goal of this dissertation is to introduce tools and methods to support the research community, as well as industrial entities and policy makers, understanding the role that flexibility assets and aggregators will play in the future Smart Grid. Here the focus is on three specific types of flexibility assets: energy storage systems, thermostatically controlled loads (TCLs) and electric vehicles (EVs). In the first part of the dissertation, a definition of aggregator is given and a Virtual Power Plant architecture for flexibility assets aggregators is introduced. Then, a series of chapters are dedicated to the single flexibility assets, using the concept of equivalent energy storage to present a common framework to model them and aggregate them. Finally, the optimal portfolio management problem for flexibility assets aggregators is presented, offering alternative mathematical approaches to solve it. A convex formulation is defined to optimally solve the resource scheduling problem, specifically targeting aggregators interested in managing the energy demand of a Urban district. All the methodologies presented are tested using either experimental, private or publicly available data.

Повний текст джерелаPower fluctuations in a microgrid are caused by disturbances due to the connection and disconnection of Distributed Generators (DG’s), as well as the irregular input of the sun and wind renewable energy. Renewable penetration such as the sun, wind and tidal energy causes intermittency which directly affects the input and resultant output power of a microgrid. Control systems have to be implemented on three different levels to ensure the stability and reliability of the power supplied to the load. This can be achieved by implementing the following: 1) Primary control with mechanical valves and actuators to translate feedback signals through droop control. 2) Secondary control with power electronics to facilitate maximum power point tracking, phase lock loops and switch mode inverters to manipulate the electrical signals to a desired set points including PID control. 3) Tertiary control with software program management to monitor the power flow as well as to evaluate congregated logic and implement decision making. Energy storage systems like super capacitors can compensate for power imbalance by providing excess stored energy to the microgrid for short periods of time. The added advantage of capacitor banks is that it can facilitate power factor correction where inductive loads like rotating motors form large part of the total load. Battery banks can compensate for energy shortage for longer periods of time. The duration of the compensation can be determined by the size, topology and the type of batteries used. The objectives of this study is to improve the unstable power output responses of a renewable energy microgrid by designing and analysing control strategies intended at power wavering compensation which also includes energy storage. Sub control systems is created and simulated in Matlab/Simulink for analytical comparative observations. Results of the simulated model are discussed and recommendations are given for future works.

Повний текст джерелаThe development of the modern society and the global continuously accelerating energy intensive way of living is putting stress on the climate. In order to achieve the UNs set of sustainability goals, including reduced emissions and more efficient use of energy, vigorous actions in the global energy system is required. To increase the share of clean and modern energy generation a larger quantity of solar and wind power is required. Due to weather dependency these resources generate intermittent electricity which will put new challenges on the grid. To facilitate the implementation of intermittent energy sources on the national grid and in smaller energy systems this report aims to investigate current prerequisites on integrating battery energy storage systems and intermittent resources to increase the share of clean energy sources in the power system. Current prerequisites are presented as the result of an extensive literature study where the electrical grid, promising battery technologies, financial incentives for battery energy storage and future potential is examined. A global commitment to increase the share of renewable energy sources using battery energy storage system in the global energy system is identified. Furthermore, battery energy storage systems are shown to have great potential in limiting the negative impact of intermittent energy sources on the electrical grid. This potential is currently being limited by existing political control means and the design of the electricity market such that small producers are benefitted by directly supplying the grid with excess electricity instead of using energy storage. With a growing share of intermittent power generation these limitations are expected to ease and battery energy storage systems in connection with power production becoming more profitable.

Повний текст джерелаCon "smart grids'' si può identificare quello che rappresenteranno le reti elettriche del futuro, ovvero un sistema integrato ed intelligente, dove ogni dispositivo disponibile a modificare la propria generazione e il proprio assorbimento, è reattivo, attento ai segnali di prezzo, consapevole del proprio ruolo, sensibile agli aspetti ambientali, flessibile e interconnesso con gli altri. In questo scenario, tecnologie intelligenti, come i sistemi ICT (Information and Communication Technologies) e gli smart meter, permetteranno le interconnesioni e le interazioni tra questi dispositivi disponibili a partecipare nei servizi ancillari; mentre un sistema di gestione intelligente dovrebbe essere in grado di assicurare qualità, affidabilità, efficienza, efficacia nel servizio di fornitura e la libera partecipazione nei servizi per il supporto della rete di questi nuovi clienti. Sebbene lo scenario identificato dal termine "smart grids'' sembri essere chiaramente definito, risulta ancora necessario lo studio relativo al sistema di gestione fondamentale per coordinare in maniera efficiente le risorse distribuite nelle reti di distribuzione e le potenzialità introdotte da nuovi possibili participanti nella regolazione della rete, come per esempio i sistemi di accumulo e i veicoli elettrici. A questo proposito, i mercati energetici sembrano ideali per aiutare l'operatore di sistema a coinvolgere tutte le risorse energetiche nella regolazione della rete, permettendo anche lo sfruttamento della singergia tra differenti vettori energetici, allo scopo di incrementare l'efficienza e l'affidabilità generale di tutto il sistema. Infatti, i mercati energetici possono creare appropriati segnali di prezzo in grado di rendere sensibili alle esigenze della rete quei dispositivi disponibili a modificare la loro generazione e il loro assorbimento. È per questo motivo che sembra opportuno identificare questi dispositivi come clienti. Il principale filo conduttore di questa tesi è stato la ricerca di procedure intelligenti di gestione per la coordinazione di differenti risorse nelle future reti energetiche intelligenti. In particolare, è stata sfruttata l'idea chiave dell'importanza dei segnali di prezzo per ottenere un comportamento virtuoso dei clienti, concentrandosi su metodi di coordinamento in grado di assicurare con meccanismi semplici la gestione di un complesso sistema come quello della rete elettrica. Nel primo capitolo di questa tesi è presente una breve introduzione alle smart grids, ai mercati energetici e ai sistemi di accumulo, al solo scopo di presentare background e motivazioni di questo lavoro. Il capitolo 2 raccoglie le basi teoriche della modellizzazione dell'ambiente software sviluppato durante il dottorato e usato per studiare la gestione in reti energetiche intelligenti. Il capitolo 3 presenta le prime indagini sulla gestione di un energy hub, un centro di generazione, conversione e assorbimento, basata su segnali di prezzo adeguati a permettere una gestione ottima di flussi tra differenti vettori energetici, in modo da sfruttare la loro sinergia. Il capitolo 4 riporta quanto studiato per la gestione di un sistema multi-vettore energetico attraverso coefficienti di prezzo. In particolare, è stata analizzata la possibilità di utilizzare termini di prezzo proporzionali ad un segnale di riferimento che rappresenti la richiesta della rete in una gestione disaccoppiata di rete ed energy hub con sistemi di accumulo. Questa precudura di ottimizzazione disaccoppiata è stata applicata nel capitolo 5 a degli agglomerati di veicoli elettrici, intesi come sistemi di accumulo flessibili e distribuiti. Nel capitolo 6, infine, viene presentata un'innovativa procedura di gestione, basata sulla filosofia del token ring, mirata a coordinare risorse distribuite assicurando la loro libera partecipazione nei servizi per il supporto della rete. La tesi si chiude con il capitolo 7, che riassume e discute i più importanti traguardi raggiunti e suggerendo possibili lavori futuri.

Повний текст джерелаDoctor of Philosophy
In hot weather areas around the world, the electrical load in a building spikes because of the cooling load, but not by the same amount daily due to various conditions. In order to meet the demand of the hottest day of the year, large cooling systems are installed. However, these large systems are not fully utilized during all hot summer days. As a result, the investments in these cooling systems cannot be fully justified. A solution for more optimal use of the building cooling system is presented in this dissertation using Cool Thermal Energy Storage (CTES) deployed at a district level. Such CTES systems are charged overnight and the cool charge is dispatched as cool air during the day. The integration of the CTES helps to downsize the otherwise large cooling systems designed for the hottest day of the year. This reduces the capital costs of installing large cooling systems. However, one important question remains - how much of the CTES should be charged during the night, such that the cooling load for the next day is fully met and at the same time the CTES charge is fully utilized during the day. The solution presented in this dissertation integrated the CTES with Photovoltaics (PV) power forecasting and building load forecasting at a district level for a more optimal charge/discharge management. A district comprises several buildings all connected to the same cooling system with central CTES. The use of the forecasting for both the PV and the building cooling load allows the building operator to more accurately determine how much of the CTES should be charged during the night, such that the cooling system and CTES can meet the cooling demand for the next day. Using this approach, the CTES would be optimally sized and utilized more efficiently. At the same time, peak load is lowered, thus benefiting an electric utility company.

Повний текст джерелаThis thesis is devoted to the study of agents called prosumers because they can, from renewable, both produce and consume electricity. If their production exceeds their own needs, they are looking to sell their surplus on electricity markets. We propose to model these prosumers from meteorological data, which has allowed us to highlight non trivial spatial and temporal correlations. This is of great importance for aggregators that form portfolios of equipments to sell services to the network operator. As an aggregator is bound by a contract with the operator, it can be subject to penalties if it does not fulfill its role. We show that these correlations impact the stability of aggregates, and therefore the risk taken by the aggregators. We propose an algorithm minimizing the risk of the aggregations, while maximizing the expected gain. The placement of storage devices in a network where generators and loads are stochastic and not fixed is complex. We propose to answer this question with control theory. We model the electrical system as a network of coupled oscillators, whose phase angles dynamics is an approximation of the actual dynamics of the system. The goal is to find the subset of nodes in the graph that, during a disturbance of the system, allows returning to equilibrium if the right signals are injected and this with a minimum energy. We propose an algorithm to find a near optimal placement to minimize the average energy control

Повний текст джерелаCurrently the world has a steadily growing population and therefore steadily growing need of energy. With a growing need of energy, discussions regarding society’s sustainability and environmental impact have risen. At the same time modern technology has resulted in society being more dependent on a constant power supply than ever before. Technological advances, together with the desire to become a more sustainable society with high availability of power, have yielded a concept known as the smart grid. Due to the power grid being a huge industry there’s a divided perception regarding what a smart grid constitutes. This has resulted in the appearance of different definitions and models of the concept. Therefore a literary study was done with the purpose of creating an overall perception of the main aspects of the smart grid. To create this overview a proposed definition has been developed that describes the smart grid as mainly sustainable and available. The smart grid is the next step of the power grid’s ongoing development in response to society’s increasing reliability of a constant power supply and the wish for decreasing man’s environmental impact. With cost efficient technical solutions, efficient technology and economic forces the goal is to promote introduction of additional renewable electricity production, increased electricity utilization and a more efficient use of the power grid – a power grid with low losses, high power quality and availability with end-users that are more aware and involved in their power consumption than before. Based on this definition the smart grid can be summarized as two main interests for society – sustainability and a higher reliability. In the future the power grid is expected to cope with an increased introduction of renewable electricity production and an increased use of electrical applications. It has been concluded that the grid capacity has to increase in order to meet these expectations. It’s been shown that an increase in grid capacity can be achieved through technical solutions as energy storage and more efficient electrical components but also through non-technical solutions as political forces and incentives for end-users to lower their peak consumption and overall electricity consumption through demand response. At present there are no clear incentives for this and it’s considered that there is a need for reform of certain parts of the electricity market to promote the development towards a sustainable smart grid. The power grid is also expected to supply end-users with a higher power quality and reliability. The power grid of today consists of long lived and, in many cases, old components and investments in modern protection systems and communication networks are required in due time to meet new expectations. In addition, the smart grid is expected to include different types of communication network within protection systems, monitoring and metering. Information was therefore summarized regarding relevant communication protocols, media and networks where different properties are suitable for different applications.

Повний текст джерелаAnvändningen av el från förnyelsebara energikällor som vind och sol kommer att påverka elnätet, som sätter en gräns för hur mycket distribuerad energiproduktion som kan anslutas. Investeringar i storskalig energilager och användning av modern kommunikationsteknologi gör det möjligt att öka andelen förnyelsebarenergi genom att nätet kan drivas närmare sina gränser. Elnät med sådana nya tekniker kallas ofta för ”Smarta Elnät". Implementering av sådana smarta elnät kan vara ett alternativ till traditionell nätplanering och åtgärder som utbyte av transformatorer eller konstruktion av nya kraftledningen.Nätets acceptansgräns är ett objektivt mått för att bestämma gränsen för nätets förmåga att integrera ny förbrukning eller produktion. Målet är att skapa större transparens och bidra till ett bättre faktaunderlag i diskussioner mellan nätoperatörer och ägare av distribuerade energiresurser. Denna avhandling utökar acceptansgränsmetoden för tillämpning med energilager och produktions nedstyrning och utvecklar ytterligare begrepp så som acceptansgränsen koefficienten.Forskningen visar hur varierbarheten hos olika förnyelsebara energikällor samverkar med förbrukningen och påverkar nätets acceptansgräns. Flera fallstudier från verkliga elnät och med uppmätt produktion och konsumtion presenteras. Fokus är på hur den tillåtna mängden förnyelsebara energikällor kan ökas med hjälp av energilagring, kontrollerad produktionsnedstyrning och med avancerad distribuerade skydd och kontroll applikationer.

Повний текст джерелаConsidering abnormal conditions to which the Electric Power System (EPS) may be subjected, the protection of its elements is an important topic. Among the equipments to be protected, the generators are highlighted, because they represent a high investment cost and are subjected to penalties for unscheduled stoppages. Hence, based on literature, it is observed that there are no comprehensive studies and standards for individual protection of Synchronous Generators (SGs) applied to Wind Energy Conversion System (WECS). Furthermore, considering the smart grids context, the presence of batteries and the possibility of island operation may change the dynamic of fault situations. Therefore, it is necessary to study and analyse the behavior of wind turbines in fault situations, knowing that the protection scheme is dependent on the generator type and the way it is connected to the EPS. In order to study these issues, this research proposed to include a battery to operate with a full-variable speed wind generator in a complementary way, smoothing the output power and making the WECS strong enough to operate in the island mode. The methodology establishes several fault types to investigate the wind turbine behavior in such conditions. In order to conduct the fault simulations, a real time digital simulator (RTDS®) was used. Based on this, a scheme composed by conventional protection functions were specified and tested using the MATLAB® software. Furthermore, hardware-in-the-loop simulations were performed with commercial and universal relays. Very good results in favor of the proposed scheme are presented.

Повний текст джерелаThe goal of the SThG® project is to recycle, to store and to manage unavoidable and renewable energies in the residential building. The aim of the work performed is to fill the lack of research on global sizing of systems, which is a barrier to the evolution of the energy balance of the building. Indeed, available tools are not adapted to make optimized choices and to size systems as they are very time-consuming. That is why an alternative model has been found. This work can be divided into two main steps. The first one, consists in doing a simplified model of a building and its systems. The second one in applying optimization to have the best choice and the better sizing of those systems according to energy and economic criterions. To solve this problem a model has been developed and two blocks can be identified. The first block is composed of two main points: the establishment of a physical model and the physical optimization. First, a macroscopic model of a building and its systems (recovery, storage and generation) has been created. This model is as much as generic as possible in order to represent a huge part of systems. But, it is also precise to ensure a good description of the real way they work and to allow the link to systems after the physical optimization during block two. Secondly, a Global Pattern Search optimization is used to find the best physical solution according to the constraints of the situation. The second block permits to find solutions in a discrete data basis of systems. These two blocks allow a durability of the tool, indeed the mechanism of optimization depends on the physical model. It will be possible to enrich the data basis of the second block without reconsidering the first one. Thanks to this work, a consistent choice and sizing of systems can be found

Повний текст джерелаThe integration of PV power generation in a power system reduces fuel consumption and brings environmental benefits. However, the PV power intermittency and fluctuations deteriorate the power supply quality. A solution is proposed by adding energy storages, which are coordinated by a local controller that controls the power flow among all sources and implements an inner energy management. This PV based active generator can generate power references and can provide ancillary services in an electric network. Then micro grid concepts are derived to design a central energy management system of a residential network, which is powered by PV based active generators and a gas micro turbine. A communication network is used to exchange data and power references. An energy management system is developed with different time-scale functions to maximize the use of PV power. An operational daily planning is designed by a determinist algorithm, which uses 24 hour-ahead PV power prediction and load forecasting. Then power references are refreshed each half of an hour by considering the PV power availability and the states of energy storage units. Prediction errors and uncertainties are compensated by primary frequency controllers. Simulation and testing results validate the design of the PV active generator local controller and the central energy management system of the studied residential network

Повний текст джерелаThe increasing variability of electricity production in Europe, which is mainly due to the intermittent production of renewables such as wind and photovoltaic (VRE), will require significant efforts to reconcile demand and supply at all times. Thus, increasing shares of variability imply increasing amounts of system services. In addition to upgraded interconnections, demand-side management (DSM) and dispatchable backup capacity, electric energy storage (EES) technologies will have a major role to play in this context.However, due to the peculiar price formation mechanism prevailing in energy-only electricity markets, the commercial case for EES is being eroded by the very forces that create the need for its increased deployment at the system level. The private incentives of EES are thus diminishing while its social value, which is determined by the multiple system services these technologies can supply, is increasing.This thesis sets out to (1) model and assess the interplays between variability, flexibility needs and decarbonization objectives, (2) analyze the role and the value of EES technologies in view of the French official objectives by 2020, 2030 and 2050, and (3) discuss regulatory aspects, and propose a set of energy policies allowing to succeed in the energy transition and decarbonization goals

Повний текст джерелаIncluding more renewable energy sources in the energy system is of great importance to enable Sweden to achieve its climate goals in unity of Agenda 2030. Sector coupling is a potential strategy for energy optimization, which in time could become a more established method to manage capacity issues, as well as permitting more renewable energy sources in the electricity grid. The purpose of this study is to compile a status report on current sector coupling in Sweden, with additional further investigation of region Gotland. The study is based on a comprehensive literature study as well as data collection through qualitative interviews with relevant stakeholders. Previous research and literature in the field enabled the identification of different technologies and methods relating to sector coupling. Qualitative data was gathered through unstructured interviews with represenatatives from companies and organizations having their focus set on energy planning in the Gotland region. The results consist of an assortment of various sector coupling technologies and their ability to increase the flexibility of the power grid and energy system in Sweden. In addition, several projects with diverse implementation of sector coupling strategies were also being mapped out. In conclusion, it became apparent that sector coupling is only at its earlier stages of implementation in Sweden. Further interest and commitment by customers and businesses is of great importance and needed to enable expansion of sector coupling technologies in Sweden. Moreover, the energy system requires standards, as well as financial incentives to promote further use of sector coupling in society.

Повний текст джерелаDissertation for the degree of candidate of technical sciences in specialty 05.14.02 - power plants, networks and systems. - National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2019. The thesis is devoted to the solution of the current scientific and applied problem in the field of providing the declared schedules of generating power plants with renewable energy sources based on the concept of virtual power plants. In the dissertation work, the methods of providing the declared schedules of generating power plants on renewable energy sources are investigated. The expediency of using the concept of virtual power plants to solve the problem is justified. The use of various types of accumulation systems as one of the elements of a virtual power plant is investigated. The analysis of existing methods and state-of-the-art-practices of implementing intelligent networks was carried out, which made it possible to select the Smart Grid Architecture Model pattern as the basis for creating the necessary infrastructure. The analysis of existing methods for determining the optimal capacity of accumulation systems and their layout has been carried out that was used to calculate minimal capacity for providing the declared schedules of generation of PV and wind power plant each 1 MW for one of the administrative centers of Ukraine. The developed computer model for studying the operation of virtual power plants that include PV and wind power with energy storage and connections to PLC allows assessing potential unbalances during generation, checking the sufficiency of the capacity of accumulation systems for various tasks, as well as testing the operation of the control system. The methodology for calculating the cost of electrical energy from storage systems has been refined, taking into account the cost of energy losses during transmission and transformation, as well as additional factors associated with renting and servicing. An algorithm for managing a virtual power plant was developed, implemented and tested with real PLC connected to mathematical model, based on using the cheapest energy source for balancing taking into account the limitations of electrical networks, power lines and transforming equipment, access to the energy market for buying and selling energy and the ability to attract active consumers. The possibility of providing the declared schedules of generation of power plants based on the concept of virtual power plants on the example of conditions of one of the administrative centers of Ukraine is shown.
