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.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"54 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80179499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"18 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85196823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"48 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78701779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.

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.","PeriodicalId":6584,"journal":{"name":"2018 International Conference and Utility Exhibition on Green Energy for Sustainable Development (ICUE)","volume":"154 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86272150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
