Over the years different optimization techniques have been developed based on analytical methods, heuristics and stochastic based approaches. Analytical methods include for example linear and quadratic optimization approaches. Metaheuristic methods like Particle Swarm optimization (PSO) and Genetic Algorithms (GA) have also been developed and researched upon. In this paper, a successive mixed integer linear optimization programming (sMILP) based method in the context of optimal reactive power flow (ORPF) is developed considering continuous reactive power flexibilities and discrete transformer tap-sets. The novel formulation of the transformer tap sensitivities indicate its efficiency of using discrete tap-settings and ease of implementation in the context of Linear Programming. This method is further compared to an already established PSO-based method subject to similar initial grid conditions and three different voltage constraint violation case studies. Results indicate the reliability and efficiency of the method.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114999818","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 high penetration of PV system may lead to voltage quality problems. Reactive power capability of inverter in PV system may be used to overcome these problems. However, there are several disadvantages that can arise due to reactive power existence in inverter PV such as an increase in internal loss of inverter, active power curtailment, and lifetime reduction of inverter. To compensate these problems, several reactive power incentive models are proposed. However, there is still no review about the current research about reactive power dispatch using inverter of PV system in distribution network as well as reactive power incentive model. Therefore, this paper contributes in providing an insight about the existing research about reactive power dispatch using inverter of PV system in distribution network as well as reactive power incentive model. This paper can be used as a guide to conduct future research about reactive power management using inverter in PV system.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131185001","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}

Solar energy is a promising renewable energy resource that is clean, eco-friendly, and abundant in nature. India is endowed with a vast amount of solar energy potential. Floating Photovoltaic (FPV) is predicted to be a better form of solar energy, which is reliable, affordable, and sustainable. It potentially solves land scarcity and cost because it can be constructed over any stable water surface like a lake, pond, reservoir, river, etc. Moreover, it generates more amount of power because of the cooling effect of water. The FPV technology has still not realized its potential in developing countries like India. This study aims to calculate and compare the energy generation, performance ratio, capacity utilization factor, cost analysis, evaporation reduction, and greenhouse gas emissions for 1 MW FPV and 1 MW Ground-mounted Photovoltaic (GPV) at Visakhapatnam city in India. The electricity generation from the FPV system is estimated to be 1.5%-3% higher than the GPV system. 1 MW FPV system could save 42 million liters of water from evaporation annually. The cost of electricity for floating solar is 4.1 INR/kWh, which is slightly higher than ground-mounted systems. This study highlights the advantages of using the FPV system over the GPV system in energy generation, water-saving, and efficiency.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129784088","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}

In order to promote the standardized development of electric vehicle wireless power transfer systems, JASO TP-13002:2013, IEC TS 61980-1:2015, SAE J2954, ISO 19363: 2020, GB/T 38775.4- 2020 (China) and other standards related to the electromagnetic environment of wireless power transfer systems have been successively released. In this paper, the electromagnetic environment limits and test methods in the above standards were compared. It can be seen that the test methods are basically similar, and the standard limits are also consistent. The electromagnetic environment for wireless charging in electric vehicles tests results showed that the values of magnetic induction inside and outside the vehicle were below the limits established in ICNIRP Guidelines.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114593352","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}

Firstly, based on the analysis and summary of the power operation historical accident, 19 power operation risk assessment indexes are selected from personnel expedition, mechanical devices and equipment, operating time and environment, and operation conditions. Secondly, in view of the risk level of power operation is a fuzzy phenomenon, a three-layer neural network model of power operation risk assessment is established, in which the assessment indexes are set as input, and five fuzzy risk memberships are output. The model introduces the risk membership degree as the output result, which can not only determine the final risk level of power operation, but also explore the potential risks in power operation according to the risk membership of power operation. Finally, through the comparison of three risk assessment methods, it is verified that this method is more reasonable and objective for power operation assessment.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121539487","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}

In fact, the local management of the reactive power of each wind power plant connected to a VHV/HV substation should be coordinated not only at the Point of Interconnection through tap regulation, amid others, but also at the individual wind power plant and photovoltaic plant. Based on a real case study in the Portuguese national transmission system, this paper presents the advantage of applying a voltage droop control strategy to avoid conflictual set-point for each wind power plant or photovoltaic plant. Different scenarios, both topological and operational, will be analyzed and developed in order to come up with a robust voltage droop control strategy that mitigates voltage fluctuations at the point of interconnection (POI) by fully utilizing the voltage regulation capability of each Wind Power Plant and photovoltaic plant. The main aim is to ensure that with the implemented control strategy the voltage stays within its steady-state limits in all performed scenarios.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124516753","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}
