Повний текст джерелаActuality of theme. The directions of the development of forestry should be based on the development of network infrastructure and generating capacity, ensuring the satisfaction of long-term and medium-term demand for electricity and power, the formation of stable and favorable conditions for attracting investments in modernization of networks. Forecasting of future indicators of electric consumption allows achieving the most important principle of forming a reliable and effective forestry work - providing a clear system balance of production and energy consumption. Therefore, research on forestry development forecasting is very relevant during the changes taking place in the country. The purpose of the study is the application and adaptation of the technocenological method for forecasting the volumes of energy consumption of the local power system. Formation of the program of modernization of the local power system of energy consumption. Tasks of research To achieve the goal, the following tasks were formulated: - Analysis of directions of development of modern local and regional power systems; - Definition of the technical policy of forestry modernization; - Forecasting of forest energy consumption using technocenological approach; - Use of technocenological analysis as forest development through the use of new equipment; - Analysis of replacement of traditional generation to flexible in forest; - Formation of the program of modernization of the system of energy consumption on the basis of technocenological approach; - Completion of the program of modernization of the forecast system for the development of forest, as a proposal for oblenergo. Object of research: operating modes of the local power system, methods of management of the system to increase its energy efficiency. Subject of research: processes of energy consumption of the local power system. Scientific novelty of the obtained results - On the basis of the analysis of forecasting the development of forestry, a program for modernizing the energy consumption system was developed on the basis of the technocenological approach, which made it possible to use the program of modernization of the system as a proposal for the oblenergo. - On the basis of the technocenological analysis, a rank analysis of forest energy consumption was constructed, an interval estimation of the results of the analysis was carried out, and elements of forest with abnormal energy consumption were identified, which made it possible to estimate the potential of introducing a flexible generation from the point of development of forest.

Повний текст джерелаTrots en positiv utveckling i tillgång till el globalt, ökandes från 76% år 1990, till 85% år 2012, så är Förenta Nationernas mål om universell tillgång till el till år 2030, långt ifrån att bli uppfyllt. 1.1 miljarder människor estimeras vara utan tillgång till el globalt, där över hälften av dessa bor i Sub-Saharanska Afrika, med majoriteten levandes på landsbygden och i extrem fattigdom. Stora utmaningar finns med innevarande elektrifierings strategin, som handlar om centraliserad elproduktion och distribution genom ett centralt elnät, detta kommer att lämna dessa människor utan el under lång tid framöver. Mikronät, ett decentraliserat energisystem, som kan producera och distribuera el, har lyfts fram som det bästa alternativet för att försörja livsförbättrande och produktivitetsökande elektricitet för samhällen på landsbygden i Afrika. Dock, trots nylig hype och utveckling i mikronät sektorn, så är spridningen av mikronät fortfarande inkrementell, beroende av en brist på genomförbarheten av att driva mikronät verksamheten i stor skala, vilket krävs för lönsamhet. Detta förklaras av den fundamentala utmaningen i att inrikta sig mot kunder i avlägsna områden, med en låg förmåga att betala, kombinerat med leveransen av dyr teknologi, och de komplex operativa strukturerna som krävs. Det finns ingen forskning eller blåkopia i industrin som visar hur man skulle kunna bedriva mikronäts verksamhets i stor skala, eller på ett lönsamt vis. Denna forskning undersöker en möjlig sådan blåkopia, med löftet att öka lönsamheten och möjliggöra en mer hållbar spridning. Utveckling av lokal kapacitet, är ett decentraliserat tillvägagångssätt för att utveckla kapacitet direkt i dessa avlägsna samhällen, genom rekrytering, färdighetsutveckling och utbildning av människor för att bli anställda för att sköta deras lokala mikronät. Resultaten i studien består av ett ramverk som visar vad utveckling av lokal kapacitet innebär, genom forskningsförslag som definierar vilka nyckelkomponenter som krävs för att skala upp en mikronäts verksamhet, tillsammans med utmaningar och möjligheter för att göra detta. Ramverket har utvecklats iterativt genom applicering av Action Research, utförd i ett småskaligt mikronät företag i Zambia som står inför en radikal expansion. Forskaren var fördjupad i företagskontexten, i hjärtat av förändringen, och på ett ingripande och deltagande sätt vänt på varenda sten för att utforska vad utveckling av lokal kapacitet är. Detta resulterade i en robust studie, förankrad i verkligheten. På grund av den kontextuellt inbäddade naturen av datan, så betyder detta även att resultaten är lokala. Det är upp till läsaren att bedöma till vilken grad resultaten kan appliceras i en annan kontext. De omfattande resultaten spänner över många olika områden i företaget, och lyckas fånga komplexiteten i vad utveckling av lokal kapacitet är. Blåkopian som utvecklades, bedömdes värdefull att utveckla vidare i företaget där studien gjorde, specifikt för dess potential att minska de operativa kostnaderna och erbjuda ett mer hållbart sätt att skala verksamheten, och i förlängningen, erbjuda ett mer hållbart sätt att sprida tillgång till el i Afrika.

Повний текст джерелаEn el context d'expansió de generadors d'electricitat renovable i distribuïda, les xarxes de distribució podrien presentar problemes d'operació. A més a més, en un context de desplegament de la xarxa elèctrica intel·ligent, les companyies distribuïdores tindran un millor coneixement de l'estat de la xarxa per prendre decisions d'operació en el dia a dia tant a nivell de mitja com en baixa tensió. Els mercats locals constitueixen una possible solució per a la resolució de congestions a les xarxes de distribució d'electricitat i reduir els sobre costos del sistema elèctric. Aquests mercats també permetrien incrementar el poder de negociació dels consumidors d'electricitat a petita escala amb capacitat de flexibilitat. Primerament s'analitza el potencial perill que poden suposar els vehicles elèctrics per a les xarxes de distribució en cas de no haver-hi gestió intel·ligent dels processos de carrega ja que podrien aparèixer nous pics de consum. Alhora, els vehicles elèctrics podrien ser part de la solució desplaçant el seu consum a la nit. El present treball inclou un algorisme de gestió de vehicles elèctrics a nivell d'edifici per a reduir el cost d'electricitat i els pics de consum. No obstant, les companyies distribuïdores necessiten una solució per als problemes de la xarxa que podrien ser diferents segons la zona o l'època de l'any. Es per això que aquest treball inclou dues propostes de mercat local per a aquests problemes. El primer mercat local esta dissenyat per a aprofitar l'avantatge dels productors d'energia renovable abans i després del mercat diari majorista sense comprometre l'operació de la xarxa de distribució. Tot i aixó, aquesta proposta de mercat local requeriria diversos canvis en matèria de regulació ja que l'operador del mercat local hauria de prendre algunes de les actuals responsabilitats de les companyies distribuïdores. Seguidament, la tesi presenta un segon mercat local per gestionar una cartera de consumidors, productors i prosumidors, com una activitat més dins de les activitats de les companyies comercialitzadores o agregadors de flexibilitat. El present document inclou una descripció dels rols, contractes i interaccions, i tres algorismes d'optimització des del més simple fins al més complex. El primer assumeix una limitació en la informació disponible de cada membre de la cartera, el segon inclou més informació però presenta limitacions d'escalabilitat, i finalment el tercer presenta un algorisme de descomposició per optimitzar la flexibilitat de manera distribuïda i així reduir el temps de computació i la complexitat de càlcul.

Повний текст джерелаEnligt lagen om kommunal energiplanering ska varje svensk kommun ha en energiplan för tillförsel för tillförsel och användning av energi. Huruvida energiplanering är ett bra sätt att styra det kommunala energisystemet är dock omdebatterat. Denna avhandling studerar innehåll i, och implementering av, ett antal svenska kommunala energiplaner. Energiplanernas effektivitet studeras på två nivåer: uppfyllelse av mål och visioner i planerna, samt hur detta bidrar till att uppfylla de nationella energipolitiska målen.
Forskningen baseras på tre studier: en studie av innehållet i tolv energiplaner från Östergötland, en studie av mål och visioner i sju energiplaner och hur energisystem utvecklats efter energiplanerna antagits, samt en fallstudie av Kungälvs kommun där mål och måluppfyllelse studerats mer utförligt. Innehåll och målformuleringar i energiplanerna har analyserats med avseende på miljö, effektiv energianvändning och systemnivå. Mål och måluppfyllelse har även analyserats med avseende på aktörer.
Resultaten visar på att de studerade energiplanerna har smal systemsyn och att de miljöanalyser som finns i planerna är undermåliga. Energiplaneringen har varit effektiv till viss del. Bäst måluppfyllelse har kommunerna när det gäller mål på en relativt låg systemnivå och när det är kommunen själv som äger frågan, exempelvis fjärrvärmeutbyggnad och energieffektivisering av kommunens lokaler. När det gäller utvecklingens bidrag till de nationella energipolitiska målen är resultaten varierande: användning av biobränslen har ökat avsevärt, medan självförsörjningsgraden på el bara ökat något. Bäst är utvecklingen när det gäller minskade koldioxidutsläpp.
Baserat på bristerna som upptäckts i de studerade energiplanerna och dess implementering förs en diskussion kring möjligheter att öka energiplaneringens effektivitet och vidga systemsynen. Förbättringar som diskuteras är att stärka kopplingen till fysisk planering, och att inkludera medborgarmedverkan och miljöbedömningar. Om kopplingen till energifrågor stärks i översiktlig planering och om även privata aktörer kommer till tals under planeringsprocessen, skulle detta kunna underlätta implementering av energiplanerna. Miljöbedömningar i sin tur kan bidra med en vidare systemsyn om mer relevanta mål i planerna. Slutligen föreslås att ramverket för miljöbedömning av planer och program (2001/42/EC) kan användas vid energiplanering eftersom det framhåller vikten av breda analyser, samråd med privata aktörer och miljöbedömningar.
Swedish municipalities are required to produce a municipal energy plan for energy supply and use. Whether energy planning is suitable to manage local energy systems, however, is subject to debate. This thesis explores municipal energy planning and development of local energy systems after energy plans were adopted to examine whether energy planning is effective. The effectiveness of energy planning is studied on two levels: in terms of whether goals in energy plans were implemented, and whether energy planning contributes to fulfilling national energy policy goals.
The research is based on three studies. In the first, the scope of twelve municipal energy plans from a Swedish region was assessed. In the second study, goals and visions in seven energy plans were analysed and compared to the development of the local energy systems. The third case involved Kungälv municipality, where the implementation of goals in its energy plan was studied more thoroughly. Scopes and goals in the energy plans were analysed from three perspectives: the environment, energy efficiency and the systems level. Goals and development were also analysed from an actor’s perspective.
The results show that the scopes of the studied energy plans have narrow systems boundaries, and that the environmental analyses presented in the plans are very basic. Energy planning was found to have been fairly effective in terms of fulfilment of goals in energy plans. Most positive developments are for goals on a relatively low systems level when the local authority owns the issue, for example district heating expansion and energy efficiency measures in public buildings. When it comes to contributing to national energy policy goals, results vary; use of biomass has increased, but selfsufficiency in electricity supply has increased only slightly. The most favourable development when it comes to energy-related emissions is the reduction of carbon dioxide.
Based on shortcomings identified in the studied energy plans and implementation, possibilities to increase the effectiveness and widen the scope of energy planning are discussed. Improvements are discussed in terms of urban planning as well as participative planning, and with respect to the environmental assessment of plans. If energy issues are included in urban planning and a participatory planning approach is used, this could facilitate the implementation of energy plans. Including environmental assessment could facilitate wide scopes and more relevant goals. It is also proposed that the EU framework for environmental assessment of plans and programmes (2001/42/EC) can be used for energy planning, since it includes a comprehensive approach, public participation, and environmental assessment.

Hydropower has sufficient resources available and is actively promoted by Governments as part of their energy matrix, but its development is constrained by the difficulty of addressing location particularities, including technical features such as geology or hydrology, and institutional features such as social acceptance, environmental constraints and the regulatory framework. Project results emerge from the interactions of these Inherent Features and the Project Architecture and do not always meet stakeholders' expectations, leading to deficient project results and lost value. This thesis proposes a methodology for prototyping projects to reflect these particularities and inform project shaping and decision-making early in the process. The proposed methodology was built on three systems engineering and project complexity frameworks, and lessons learned from four case studies. Its contribution to hydropower development is related to (i) the incorporation of systems evolution over time on the development process, (ii) the identification and management of relationships among the various decomposed elements of the development, (iii) the identification of emergent properties from the interactions among all features, (iv) a prototype for developers to optimize or search for project architectures that meet stakeholders objectives while complying with restrictions, (v) the delivery of unbiased information for decision-makers, (vi) the opportunity of stakeholders to participate in the project shaping in a continuous fashion, and (vii) the delivery of a tool for the implementation team to evaluate and challenge changes to the project during construction. The usage of this methodology does not guarantee the avoidance of errors or unforeseen project outcomes, but it does reduce the chance for unknown risks emerging from the interactions of the evaluated features.

Повний текст джерелаThe application of digital control techniques has become dominant in power electronics owing to several advantages they present, when compared to analogue solutions. Their development is based on the use of microprocessors and microcontrollers, such as Application Specific Integrated Circuit (ASIC), Digital signal processors (DSP), Field Programmable Gate Arrays (FPGA), or a combination of these devices. This thesis presents an investigation of a soft-core based FPGA control system as a solution for power electronic applications. The aim was the development and implementation of a conversion controller, which purpose is to supply control inputs in the form of digital Pulse Width Modulation (PWM) signals, to a number of power electronic applications, such as single half and full bridge DC-DC converters, three phase and multicell inverters. The PWM control technique is achieved via their power semiconductor switching devices. These PWM control signals are necessary for the high frequency conversion of an analog input voltage (AC, DC or unregulated) to an analog output voltage of another level (AC or DC). This was intended to be achieved by exploiting and combining the advantages that FPGA and embedded processors provide such as high reconfigurability and multipurpose ability. This controller’s digital outputs, namely PWM switching signals, can be directly delivered to an analog signal amplification circuit to create an adequate voltage level before being processed by the converters’ switches.
