E. Sosnina, A. Shalukho, I. Lipuzhin, Alexander Yu. Kechkin, A. A. Voroshilov
The article is devoted to the construction of the Virtual Power Plant (VPP) distribution network (DN), which unites sources of distributed generation and a centralized electrical network. Graph theory and structural-topological analysis are used to determining the optimal VPP DN topology. The main idea is to assess the reliability and efficiency of VPP DN on the basis of structural-topological characteristics of its graphs. The results of calculations for a low-voltage VPP DN with a wind power plant and a gas piston unit are presented. The PSCAD model of VPP DN is described, which explores the dependencies of VPP DN parameters on its topologies and operating modes. A physical model VPP DN has been developed: it consists of simulators of wind and solar power plants, power storage devices, loads and power lines. On the basis of the physical model, a study of the quality of electricity in VPP DN depending on the ratio of the power of the centralized electrical network and the distributed generation sources has been carried out. Based on the results of the study, an algorithm for determining the optimal VPP DN topology has been developed.

Experimental Verification of Electrostatic Precipitator Stable Operation Under Oil and Co-fuel Firing Conditions of a Coal-fired Power Plant 燃煤电厂燃油和共燃料工况下静电除尘器稳定运行的实验验证
A. Hoang, T. Nguyen, M. Nguyen
Electrostatic Precipitators are usually put into service after a complete shut-off of oil supply to the boiler burners of the furnace of a coal-fired power plant. However, such practice may lead to enormous dust concentration in the flue gas (design value is 37.9 g/Nm³ at 50%RO load) and heavy black smoke appearing at the stack outlet during the oil and/or co-fuel firing condition of boiler. To minimize such problem, an experimental study on charging and electrostatic precipitator operation during unit start-up and shut-down was carried out to verify de-dusting performance. It requires the manual control of the secondary voltages to be lower than sparking voltage of 10~15kV in case of oil and/or co-fuel firing condition of boiler. The study results prove that the electrostatic precipitator runs normally with good de-dusting performance (about 56.4 mg/Nm3 at unit start-up and within 31 mg/Nm3 at unit shut-down) and meets the Vietnamese environmental emission requirements as per proposed specified rules. From the study results, it can be predicted that Electrostatic Precipitators (ESP) & Sea-Flue Gas Desulphurization System (FGD) may be kept running during house load operation and run-back modes. Also, with the ESP and FGD running, the coal-fired power plant may not be limited to the loading dispatch at stable loads under co-firing condition below the minimum load of anthracite coal firing as required from power system.
电除尘器一般是在燃煤电厂炉膛锅炉燃烧器完全断油后投入使用。然而,这种做法可能导致烟气中粉尘浓度过高(50%RO负荷时设计值为37.9 g/Nm³),并且在锅炉燃油和/或共燃料燃烧状态下烟囱出口出现重黑烟。为了最大限度地减少这一问题,在机组启动和关闭期间进行了充电和静电除尘器运行的实验研究,以验证除尘器的除尘性能。要求在锅炉燃油和/或共燃工况下,人工控制二次电压低于10~15kV的火花电压。研究结果表明,该静电除尘器运行正常,除尘性能良好(机组启动时约56.4 mg/Nm3,机组停机时在31 mg/Nm3以内),符合越南提出的规定规则的环境排放要求。从研究结果可以预测,静电除尘器(ESP)和海上烟气脱硫系统(FGD)在负荷运行和回流运行两种模式下都可以保持运行。同时,随着电除尘器和烟气脱硫的运行,燃煤电厂可以不局限于电力系统要求的低于无烟煤最小燃烧负荷的共烧条件下稳定负荷的负荷调度。

Multi-Objective Optimization for Enhancing System Coordination Restoration by Placement of Fault Current Limiters on an Active Distribution System with System Reliability Considerations 考虑系统可靠性的有源配电系统故障限流器多目标优化
Rachawadee Puangsukra, J. Singh, W. Ongsakul, F. Gonzalez-Longatt
Nowadays, customer satisfaction relies on not only the power delivery, but also in the system reliability. It results a number of measures adopted by utility for reliability improvement. Moreover, distributed generators (DGs) are also enhanced to integrate to distribution system because DGs improve system reliability and capability. However, DGs can lead to mis-operation of protective devices and wider outage areas in power system due to increase in fault level. Moreover, system outage is the vital cause which decreases the system reliability. To mitigate escalation of fault level, fault current limiters (FCLs) are installed to limit incremental fault generated by DGs and improve system reliability. However, to enhance effectiveness of FCLs installation, non-dominated sorting particles swarm optimization (NSPSO) is adopted to find the optimal placement of FCLs. Moreover, novel binary particle swarm optimization and continuous particle swarm optimization are performed optimization simultaneously for selecting installed locations. Therefore, three objectives are considered in optimization process consist of to minimize total cost of fault current limiters installed, to minimize total different of margin operating time of main and backup relay pairs and to maximize system reliability. The optimal results are the set of various solutions conform with multi-objective placed in pareto optimal front, and the result show effectiveness of combined continuous-binary NSPSO. The optimization process is carried out on IEEE 33-bus and IEEE-69 bus radial system.
如今,客户满意度不仅取决于电力输送,还取决于系统的可靠性。由此得出了电力公司为提高可靠性而采取的一系列措施。此外,由于分布式发电机提高了配电系统的可靠性和性能,因此分布式发电机也被增强到集成到配电系统中。然而,由于故障水平的提高,DGs可能导致保护装置误操作,导致电力系统停电范围扩大。此外,系统中断是降低系统可靠性的重要原因。为了缓解故障级别的升级,安装了故障限流器(fcl),以限制dg产生的增量故障,提高系统可靠性。然而,为了提高燃料电池的安装效率,采用非主导分选粒子群优化(NSPSO)来寻找燃料电池的最佳放置位置。同时进行了新型的二元粒子群算法和连续粒子群算法对安装位置的选择进行了优化。因此,在优化过程中要考虑三个目标:安装故障限流器的总成本最小,主备继电器对的裕度运行时间总差最小,系统可靠性最大化。最优结果是符合pareto最优前沿多目标的各种解的集合,结果表明了连续二值组合NSPSO的有效性。在IEEE 33总线和IEEE-69总线径向系统上进行了优化。

Raghavender D. Goud, R. Rayudu, C. Moore, Tony Auditorey
A reliable and robust earthing system design is critical for the lightning protection system of a wind turbine. This paper presents an analysis of the wind turbine earthing impedance and potential rise for a horizontal multi-layer soil model in the event of a direct lightning strike on the wind turbine generator. The influence of soil resistivity and lightning current wave shapes on the wind turbine grounding impedance are analysed. The results show that the wind turbine earthing system is more vulnerable to high frequency components of the lightning strikes. The other findings highlight the impact of soil resistivity values and frequencies over the impedance and potential distribution of the wind turbine generator earthing system.

TRNSYS Software Used for the Simulation of the Dynamic Thermal Behavior of a F2-building in Lokossa City in Benin Republic TRNSYS软件用于贝宁共和国Lokossa市二层建筑的动态热行为模拟
H. Aristide, M. Anjorin, O. Salomon, Dankoro Sadate, Nepo Ferdinand Morel, Vianou Antoine, D. Gerald
The present study was based on the use of TRNSYS software for the simulation of the dynamic thermal behavior of a F2 building in Lokossa, Benin Republic. The results showed that between 00 AM and 07AM, the temperature of the indoor air is approximately 20 ° C and increases gradually until 02 PM when the temperature reaches its peak 30 ° C. However, the total incident solar radiation receives varies from a face to another and the roof received the largest due to its horizontal orientation. The heat received by a face reaches its peaks dependently on its orientation. There is a phase shift in the heat transfer received by the envelope. This is possible due to the thermal inertia of the envelope’s constituent materials, property that allows the building envelope to dampen the heat received and to phase out the transmission time to ensure thermal comfort in the home.
本研究基于TRNSYS软件对贝宁共和国Lokossa一座F2建筑的动态热行为进行模拟。结果表明:在00 AM ~ 07AM期间,室内空气温度约为20℃,并逐渐升高,直到02 PM达到最高温度30℃,但不同面接收的总入射太阳辐射不同,屋顶因其水平朝向而接收的最大。一个面所接受的热量的峰值取决于它的朝向。包络层接受的热传递中有相移。这是可能的,因为围护结构组成材料的热惯性,使得建筑围护结构能够抑制接收的热量,并逐步减少传输时间,以确保家庭的热舒适。

Automatic Sun Tracking for the Enhancement of Efficiency of Solar Energy System 提高太阳能系统效率的太阳自动跟踪
P. Sahu, N. S. Maurya, Sarita Sahu
Energy is the prime component for the development of a nation. Enormous amount of fossil fuels, viz. coal, gas, oil, etc. are extracted, converted, distributed and consumed by the society on daily basis for various activities. The limited stock of fossil fuels and its end result as global warming forced scientists to harness energy from nonconventional resources. Renewable energy, such as solar, wind, geothermal, ocean tidal waves are the best proven sources of energy. Solar energy is one of the most abundant and cheap resources among these. Solar energy is converted into electrical energy with the help of photovoltaic solar panels. Solar energy is maximized when the sunrays fall perpendicular on the panel. The rigid fixed type conventional solar panels have restriction to receive maximum sunrays because of changing angle of incidence. Automatic sun tracking system is the solution to harness maximum solar energy by facing the sun whole day.
能源是一个国家发展的主要组成部分。大量的化石燃料,即煤、天然气、石油等,每天被社会用于各种活动的开采、转化、分配和消耗。化石燃料的有限储量以及全球变暖的最终结果迫使科学家们从非常规资源中获取能源。可再生能源,如太阳能、风能、地热能、海洋潮汐波等都是已被证实的最佳能源。太阳能是其中最丰富、最廉价的资源之一。太阳能在光伏太阳能板的帮助下转化为电能。当太阳光垂直落在面板上时,太阳能最大化。刚性固定式传统太阳能电池板由于入射角的变化,限制了其最大接收太阳光的能力。自动太阳跟踪系统是利用太阳能最大的解决方案,面对太阳一整天。

D. Pamungkas, M. Pipattanasomporn, S. Rahman, N. Hariyanto, Suwarno
This paper discusses and compares three alternatives to reduce electrical energy consumption (kWh) and peak demand (kW) in buildings, namely deployment of rooftop solar PV, battery energy storage and HVAC set point adjustments. The building model of a warehouse located in Alexandria, VA, was developed in eQUEST, and its electrical consumption was validated with metered data. To perform the overall analysis, adjustment of HVAC set points was conducted in eQUEST, while Solar PV and battery models were developed and deployed on top of the developed eQUEST building model. Overall, the method presented here can serve as a guideline for building owners to analyze energy savings/peak demand reduction alternatives, of which benefits are varied from buildings to buildings based on building sizes, electricity tariffs, climate zones and building operation.

A. M. Thakare, S. Deshmukh
The use of solar energy for environmental control is receiving much more attention as a result of the projected world energy shortage. Cooling is particularly attractive as a solar energy application because of the near coincidence of peak cooling loads with available solar power.This paper describes the performance analysis of intermittent solar adsorption cooling system with composite adsorbent and water as a refrigerant. The composite adsorbent used in the system is 25 % activated carbon and 75 % silica gel. The system consists of adsorption container integrated with solar flat plate collector with absorber area of 0.9 m2 and contains a porous adsorbent medium. The other components of the system are condenser, evaporator, cooling cabinet and valves. The system works on the thermodynamic adsorption cycle.The cooling load of 10 liters of water at a temperature of 35 degree Celsius was introduced in the cooling cabinet before the start of cycle. At the beginning of each test the adsorbent was heated with the help of solar energy. The chilled water with temperature reduction of 77 % is produced. The solar coefficient of performance of 0.088 and the cooling coefficient of performance is 0.83 is obtained for 10 liters of water load.
由于预计世界能源短缺,利用太阳能进行环境控制正受到更多的关注。冷却作为太阳能的一种应用特别有吸引力,因为峰值冷却负荷与可用的太阳能几乎一致。本文介绍了以复合吸附剂和水为制冷剂的间歇性太阳能吸附冷却系统的性能分析。系统中使用的复合吸附剂为25%活性炭和75%硅胶。该系统由吸附容器和太阳能平板集热器组成,吸收面积为0.9 m2,内含多孔吸附介质。系统的其他部件是冷凝器、蒸发器、冷却柜和阀门。该系统工作在热力学吸附循环上。在循环开始之前,在冷却柜中引入了温度为35摄氏度的10升水的冷却负荷。在每次试验开始时,吸附剂在太阳能的帮助下加热。生产出温度降低77%的冷冻水。在10升水负荷下,太阳能性能系数为0.088,制冷性能系数为0.83。

Relationship between Renewable Energy Consumption and Sustainable Economic Growth: The Case of Turkey 可再生能源消费与可持续经济增长的关系:以土耳其为例
Orhan Çoban, Fatma Nur Yorgancıla, Ayşe Çoban
Energy is a fundamental factor in increasing individual and social well-being. The sustainability of growth depends on the diversification of energy resources. Dependence on foreign energy, such as Turkey’s national income in countries with high employment, investment opportunities, environmental factors, and the importance of security of energy supply in areas such as renewable energy resource diversification is increasing with each passing day. In this study, by considering Turkey’s renewable energy potential, it aimed to analyze the relationship of economic growth-renewable energy consumption.According to the results of the analysis, all the variables except for GDP-GEO variables have reached to the result that they act together in the long run. In addition, a one-way causality relationship between GDP, WIND, SOLAR and HYDRO was established and it was determined that BIOMASS and HYDRO variables are positive and GEO variable has negative effect on GDP.
能源是提高个人和社会福祉的基本因素。经济增长的可持续性取决于能源的多样化。对外国能源的依赖程度,如土耳其的国民收入在就业、投资机会、环境因素以及可再生能源资源多样化等领域对能源供应安全的重要性与日俱增。本研究通过考虑土耳其的可再生能源潜力,旨在分析经济增长与可再生能源消费的关系。分析结果表明,除GDP-GEO变量外,所有变量在长期内都达到了共同作用的结果。此外,还建立了GDP与WIND、SOLAR和HYDRO之间的单向因果关系,确定了生物质和HYDRO变量对GDP的影响为正,GEO变量对GDP的影响为负。

Effects of Increasing Power Electronics on System Stability: Results from MIGRATE Questionnaire 增加电力电子对系统稳定性的影响:来自MIGRATE问卷调查的结果
V. Sewdien, M. V. D. van der Meijden, T. Breithaupt, L. Hofmann, D. Herwig, A. Mertens, B. W. Tuinema, J. R. Rueda Torres
Power systems throughout the world are experiencing increasing levels of power electronics interfaced generation in their generation portfolio. As these devices have a significantly different dynamic behavior than conventional synchronous generators, it is expected that this trend will pose power system stability related challenges. This paper presents the results of a questionnaire conducted within the MIGRATE project. The aim of this questionnaire, to which more than 20 European transmission system operators (TSOs) responded, was to identify and prioritize these challenges. The TSOs identified challenges related to rotor angle stability (two), frequency stability (three), voltage stability (five), and power electronics interactions and resonances (two). In a follow-up survey, the TSOs were asked to rank the challenges based on their severity, probability of occurrence, and time of manifestation. The decrease of inertia was ranked the highest among the 11 issues. Additionally, the TSOs gave insight into current practices with regards to system monitoring and analysis. Based on the ranking, mitigation measures are currently being designed in order to facilitate an even higher amount of power electronics interfaced renewable energy sources in the power system.
世界各地的电力系统在其发电组合中正在经历越来越多的电力电子接口发电。由于这些设备与传统的同步发电机具有明显不同的动态特性,预计这一趋势将给电力系统的稳定性带来挑战。本文给出了在MIGRATE项目中进行的问卷调查的结果。超过20家欧洲输电系统运营商(tso)回应了这份调查问卷,其目的是确定并优先考虑这些挑战。tso确定了与转子角度稳定性(2)、频率稳定性(3)、电压稳定性(5)和电力电子相互作用和共振(2)相关的挑战。在后续调查中,tso被要求根据其严重程度、发生概率和表现时间对挑战进行排名。在11个问题中,惯性的减少排在第一位。此外,tso提供了有关系统监测和分析的当前实践的见解。根据排名,目前正在设计缓解措施,以促进电力系统中与可再生能源接口的更多电力电子设备。
