Abstract:

<abstract> <p>This paper analyzes the effect of meteorological variables such as solar irradiance and ambient temperature in addition to cultural factors such as consumer behavior levels on energy consumption in buildings. Reducing demand peaks to achieve a stable daily load and hence lowering electricity bills is the goal of this work. Renewable generation sources, including wind and Photovoltaics systems (PV) as well as battery storage are integrated to supply the managed home load. The simulation model was conducted using Matlab R2019b on a personal laptop with an Intel Core i7 with 16 GB memory. The model considered two seasonal scenarios (summer and winter) to account for the variable available energy sources and end-user electric demand which is classified into three demand periods, peak-demand, mid-demand, and low-demand, to evaluate the modeled supply-demand management strategy. The obtained results showed that the surrounding temperature and the number of family members significantly impact the rate of electricity consumption. The study was designed to optimize and manage electricity consumption in a building fed by a standalone hybrid energy system.</p> </abstract>

Abstract:

This study evaluated the effect of increased energy via supplementation on the performance, ingestive behavior, nutrient digestibility, and nitrogen metabolism of grazing heifers fed tropical forage in the rainy-dry transition season. Treatments consisted of mineral supplementation ad libitum (control) and multiple supplements formulated to provide different energy levels and the same amount of protein (300 g CP animal d-1) and were denominated as low (LE; 340 g TDN animal d-1), medium (ME; 780 g TDN animal d-1) and high (HE; 1220 g TDN animal d-1) energy. Animals supplemented with ME, and HE had a greater average daily gain in relation to the control treatment, with an increase of 41 and 46%, respectively. Greater values for total apparent digestibility of neutral detergent fiber were observed for the treatment HE. Lesser values of urinary urea N were observed for the control and HE treatments. Our results define the use of energy levels in the supplement as a tool for pasture management. If the purpose of the production system is to enhance forage intake, the option is to supply supplements with less energy levels. In contrast, if the purpose is to increase the stocking rate, supplements with greater energy levels should be used.

Abstract:

A bidirectional dc/dc on-board charger for EV battery discharging/charging application is a preferable choice for V2G and G2V compatibility. It is useful for EV applications since isolated converters favour working with high power densities over a variety of loads. The bidirectional converter performs the stepup and stepdown operation at zero voltage switching for all power switches in both directions. EVs can be connected to the grid using either direct or indirect architectures, which are two different forms of architecture. Under the direct architecture, there is just one communication channel available for use by the EV and the grid system operator. The older design is the main topic of this essay. When electric vehicles (EVs) connect to the grid to provide various V2G services, they participate in continual charge-discharge cycles. These cycles may be of great concern to the owners of the vehicles because the cost associated with the degeneration of the EV batteries needs to be investigated and analysed. The strategy based on reinforced learning will be able to present a solution which is close to the optimal solution achieved by suing dynamic programming.

Abstract:

Large-scale data streams processing is now fundamental to many data processing applications. There is growing focus on manipulating Large-scale data streams on GPUs in order to improve the data throughput. Hence, there is a need to investigate the parallel scheduling strategy at the task level for the Large-scale data streamsprocessing, and to support them efficiently. We propose two different parallel scheduling strategies to handle massive data streamsin real time. Additionally, massive data streamsprocessing on GPUs is energy-consumed computation task. So we consider the power efficiency as an important factor to the parallel strategies. We present an approximation method to quantify the power efficiency for massive data streams during the computing phase. Finally, we test and compare the two parallel scheduling strategies on a large quantity of synthetic and real stream datas. The simulation experiments and compuatation results in practice both prove the accuracy of analysis on performance and power efficiency.

Abstract:

The increasing demand to reduce the high consumption of end-use energy in office buildings framed the objective of this work, which was to design an intelligent system management that could be utilized to minimize office buildings’ energy consumption from the national electricity grid. Heating, Ventilation and Air Conditioning (HVAC) and lighting are the two main consumers of electricity in office buildings. Advanced automation and control systems for buildings and their components have been developed by researchers to achieve low energy consumption in office buildings without considering integrating the load consumed and the Photovoltaic system (PV) input to the controller. This study investigated the use of PV to power the HVAC and lighting equipped with a suitable control strategy to improve energy saving within a building, especially in office buildings where there are reports of high misuse of electricity. The intelligent system was modelled using occupant activities, weather condition changes, load consumed and PV energy changes, as input to the control system of lighting and HVAC. The model was verified and tested using specialized simulation tools (Simulink®) and was subsequently used to investigate the impact of an integrated system on energy consumption, based on three scenarios. In addition, the direct impact on reduced energy cost was also analysed. The first scenario was tested in simulation of four offices building in a civil building in South Africa of a single occupant’s activities, weather conditions, temperature and the simulation resulted in savings of HVAC energy and lighting energy of 13% and 29%, respectively. In the second scenario, the four offices were tested in simulation due to the loads’ management plus temperature and occupancy and it resulted in a saving of 20% of HVAC energy and 29% of lighting electrical energy. The third scenario, which tested integrating PV energy (thus, the approach utilized) with the above-mentioned scenarios, resulted in, respectively, 64% and 73% of HVAC energy and lighting electrical energy saved. This saving was greater than that of the first two scenarios. The results of the system developed demonstrated that the loads’ control and the PV integration combined with the occupancy, weather and temperature control, could lead to a significant saving of energy within office buildings.

Abstract:

<abstract> <p>This paper proposes a design of energy balance circuit for two adjacent Lithium-ion battery cells in the cell string based on the modifying of the bidirectional CuK converter principle. This design only uses one MOSFET to transfer energy between two cells in a direction controlled by the first relay, second relay controls the cutting energy balance circuit off the cells when they have the same energy level. The control command sent by the management battery system (BMS) to the energy balance circuit via an RS485 communication protocol controls the direction of transferring energy, the amplitude of the balance current, the frequency and duty of PWM, the PWM signal applied to MOSFET is programmed by a microprocessor PIC18F2685. This design overcomes some disadvantages caused by applying the principle of bidirectional CuK converter to design the energy balancing circuit, these are the need for a multiple level DC source to open MOSFETs and issue of the energy loss on the elements of energy balance circuit. This design is also easy to expand for the battery string with a large number of cells. The energy balance control strategy can be implemented directly by each the energy balance circuit or remotely by BMS using RS485 communication. The experimental results of online optimal energy balance control based on state of charge (SoC) feedback for 07 SAMSUNG 22P battery cells connected in series are presented to prove the efficiency of the energy balance circuit design for two adjacent cells proposed in this paper.</p> </abstract>

Abstract:

Forest Management in Java is carried out by Perum Perhutani, which has implemented a Community-Based Forest Management (PHBM) system. Pringapus Kecanatan has a State Forest which is quite extensive, however, most of the population around the forest is still in poor condition. The condition of the community around the forest in Pringapus District is illustrated by the people who do not have independence, do not have access to use the forest, the level of education and skills are still low. In an effort to overcome all this, Perum Perhutani is empowering the community in Pringapus District through the Community Forest Management System. This system is considered quite strategic because it is very accommodating to the interests of various parties including the community as the agents of development. This study aims to evaluate the implementation of the Collaborative Forest Management System (PHBM) from the Institutional aspect, the Empowerment aspect, the Agribusiness aspect and the LMDH Role aspect and formulating a community empowerment strategy through the PHBM. Analysis of the data used to answer the objectives is descriptive analysis, multiple linear regression analysis and SWOT analysis. The results of PHBM research in Pringapus sub-district indicate that the institution is being illustrated by the lack of realization of work programs as well as sub-optimal level of LMDH participation

Abstract:

Using cascade utilization between multiple energy sources to realize multi-energy complementarity can significantly improve the economic benefits and energy utilization of integrated energy service providers. Integrated energy service providers consider the cascade utilization of energy in the regional energy system. Through the demand response management of user power loads and different qualities of heat energy, the energy loss of the system can be reduced and the energy utilization efficiency of the system can be further improved. In this paper, we creatively establish a multi-objective optimization model with the goal of a minimum total cost and minimum exergy loss, considering cross elasticity, which is solved with the constraints of equipment operation and the energy balance in the region. The calculation example proves that the implementation of energy cascade utilization and demand response management for different users, by integrated energy service providers, can effectively reduce the system cost and improve exergy efficiency, so as to realize the optimal management of economic utilization and energy value.

Abstract:

Abstract Photovoltaics have the advantages of being clean and renewable and have gained a wide range of applications. It is promising to use photovoltaic energy for the power supply of buildings, as the building sector accounts for a large portion of global energy consumption with a constantly increasing trend. However, photovoltaics are greatly affected by time and environment, and it is usually combined with batteries to form a photovoltaic–battery energy storage system to meet the load demand. This paper aims to analyze and compare energy management strategies of an on-grid solar photovoltaic–battery system for a real building project in a typical May and October region, but unlike other studies, the strategies used in this paper are very simple and easy to implement. It can also realize photovoltaic, battery and grid to meet the load power demand. Two strategies are used in this paper. Strategy 1 is to maximize the utilization of the energy generated by photovoltaics: while the energy generated by photovoltaics cannot meet the load demand, the battery will provide energy, and while the battery cannot meet the load demand, the grid will provide energy. The photovoltaic energy is given priority to the battery under the premise of meeting the load demand. Strategy 2 is to use the time-of-use electricity price, and the battery obtains cheap electricity at night to meet the load of the high electricity price the next day. The feasibility of the strategy used is demonstrated by actual data of buildings and photovoltaic–battery energy storage systems. This study can provide theoretical references for the energy management and system operation to facility managers and building occupants.

Abstract:

This paper studies the energy management problem of a seaport integrated energy system under the polymorphic network. Firstly, with the diversity of energy devices, a seaport integrated energy system based on the polymorphic network is established to ensure information exchange and energy interaction between heterogeneous devices, including the service layer, control layer, and data layer. Secondly, by analyzing the characteristics of different loads and the energy conversion hub, such as the power to gas (P2G) and combined cooling heating and power(CCHP), the energy management model for the seaport integrated energy system is constructed. Finally, we obtain the optimal solution by mixed integer linear programming, and the proposed strategy is used to a seaport integrated energy system including CCHP, P2G, clean energy and energy storage device. By comparing four different cases, the simulation results show a reduction in the cost of energy purchase and carbon emissions when applying our strategy with various device types and device failures. Moreover, considering the application of the proposed energy management strategy under seasonal variations, the optimal solution for the energy management problem of the seaport integrated energy system is obtained.

Abstract:

The fluctuation of production of renewable energy resources (RESs) is a big problem for its installation and integration in isolated residential buildings. A hybrid AC/DC microgrid facilitates the good operation of RESs with a storage system in standalone mode and the possibilities of smart energy management. In this paper optimization research of the hybrid ac/dc microgrid in isolated mode of operation is presented. The power system is supplied by various Renewable Energy Resources (RESs), Photovoltaic arrays (PVA), a Wind Turbine Generator (WTG), Diesel Generator (DG) and supported by Batteries Storage System (BSS) for short term storage. The main objective of this study is to optimize power flow within a hybrid ac/dc microgrid with regards to reliability in islanded mode. First a mathematical model optimized by mixed integer linear programming and solved by CPLEX solver with JAVA language is developed for an islanded RES system and then, based on the developed model, the power system control is simulated for different cases of off-grid mode. Simulation results have shown that the management strategy can maintain power balancing while performing optimized control and give a controllable loads and batteries charging/discharging powers, even with unpredictability of RESs powers outputs and arbitrary energy tariffs. Finally, the proposed algorithm respects the optimization in real-time operation under various constraints.%.©2020. CBIORE-IJRED. All rights reserved

They do not have enough time to deal with organizations’ future development. A strategic management is a process of developing an organization’s objectives, strategic plan, and allocating resources to implement the plan. Basically a strategic management covers strategy analysis, strategy formulation, strategy implementation, and strategy evaluation. A strategy analysis is to provide information on strengths and weaknesses of internal organization factors: human resources, organization structure, program performance; and information on opportunities and threats of external organization factors, politic, economy, social, and technology. A strategy formulation is a process of developing strategic plan including organization value, mission, vision, goal, strategic objectives, strategic issues, and strategy. A strategy implementation involves with the organization structure, value, operational activities, leadership, resource allocation, and communication. Strategy evaluation includes monitoring and evaluation activities to identify progress of the program implementation and to identify program achievement and its performance. A strategic management process provides a guide for addressing internal and external organizational challenges and changes using a new bussiness method and approach for practical application and maintaining flexibilities, Through a straqtegic management, the managers and executives will be able to provide better quality of services effecively and efficienly.Keywords: Management, strategic, not for profit

Abstract:

In this paper, an energy management strategy for electric vehicles equipped with fuel cell (FC), battery (BAT), and supercapacitor (SC) is considered, aiming at improving the whole performance under a framework of vehicle to network application. In detail, based on wavelet transform and equivalent consumption minimization strategy (ECMS), the demand power of vehicles is optimized to enhance the lifespan of fuel cell, fuel economy, and dynamic performance of electric vehicles. The wavelet transform is used to separate the high-frequency power in order to provide a peak power and recycle the braking energy. The equivalent consumption minimization strategy is used to distribute the low-frequency power to fuel cell and battery for minimizing the hydrogen consumption. Obtained results are studied using an advanced vehicle simulator, and its effectiveness of the strategy is confirmed, which provides a fundamental control method for the IOV application.

Abstract:

Sustainable foreign economic activity of gas industry enterprises was done in frames of project management approach in energy company (the case of JSC "Samruk-Energo"). We have considered from the perspective of development of the area of a region where projects are being implemented in the energy sector in this region, as in the analysis and subsequent evaluation of projects is difficult to identify purely economic component of the project to assess the effectiveness of the project and management. In our view, this should be approached from the perspective of sustainable development, not only the company but also the region. Especially, it is necessary to take into account the company's development strategy, which positions itself as a company that creates value for shareholders, employees and society as a guarantor of Kazakhstan's high-tech energy and supplier of Eurasia, guided by the principles of the care of the environment and lean manufacturing

Abstract: Application of the concept of sustainable development requires integration between the micro scale (building), meso scale (building group) and macro scale (city). Since 2008, ASEAN has rewarded hotels in the world that meet environmentally sound hotel standards. The Ministry of Tourism and Creative Economy has appreciated and organized the award of the National Green Hotel Award since 2011. This research focuses on identifying and analyzing sustainable design strategies at three hotels in Jakarta and Bali covering efficiency, conservation and management of various elements: land, energy , water, materials, air and indoor health, and environmental management. The analysis used normative architectural criticism approach on the standard study in designing hotel buildings that applied the concept of "green hotel" to the hotel building cases that are considered to meet the criteria. As a result, the hotel's green architecture strategy uses a "green" principle that covers aspects of the cultural, social and economic life cycle; structural design efficiency; energy efficiency; water efficiency; efficiency of building materials; improvement of inner space quality; operational and maintenance optimization; and waste reduction.Keywords: design strategy, sustainable architecture, green hotelAbstrak: Penerapan Konsep Pembangunan Berkelanjutan memerlukan integrasi antara skala mikro (bangunan), skala meso (kelompok bangunan) dan skala makro (kota).

Abstract:

The Bevano river flows into the northern Adriatic Sea in a microtidal-low energy wave environment. The river mouth was diverted artificially in 2006 to contrast dune erosion and decrease inland river flooding. The intervention can be considered as a low impact one as the engineering works were constructed in timber and the possibility of the inlet naturally changing its course was contemplated. An ensemble of hydraulic/morphological scenarios was simulated using data from field surveys and a coupled numerical model. The aim of the modeling was to understand the morphological changes caused by extreme hydro-meteorological events and the relationships between the inlet and the adjacent beaches. Additionally, the probability of a second inlet opening either by overwashing or river breaching was another important topic considered for management purposes. The modeling found that, a second inlet can actually be opened under a 30 year flood occurring without any significant wave action. For other conditions, the current inlet will be the main source of water escape at sea. Finally, the modeling results confirmed the dominance of the ebb tide in creating a small ebb delta/swash bar, with many similarities with other inlets exposed to a larger tidal range. Currently the management strategy by competent authorities is a minimum maintenance option, with yearly repairs of the timber structures.
