Aside from power losses, minimizing voltage deviation is also an important aspect of reactive power optimization. Traditional reactive power optimization only considers the optimization effect of a single period, not the overall day's optimization. In view of this, a multi-objective dynamic reactive power optimization model is established in this paper, with the objective of minimizing the active power losses and voltage deviation, and the constraints of OLTC and RPC equipment. The second-order cone relaxation (SOCR) is used to convert the mixed integer nonlinear programming (MINLP) problem into the mixed integer second-order cone programming (MISOCP) problem, and the multi-objective variable-weight method is adapted to achieve the multi-objective dynamic reactive power optimization. Case studies are carried out on the modified IEEE 33-node system to verify the feasibility and effectiveness of the proposed method.","PeriodicalId":252797,"journal":{"name":"2022 4th Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117154763","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, building a distributed parameter model of the line, the expression of harmonic measured impedance of the grounding electrode line under different fault conditions is derived, and the different characteristics of the harmonic measured impedance were analyzed by using the impedance expressions. Based on this, a fault protection criterion based on the impedance amplitude and phase deviation are constructed. The theoretical analysis and simulations results show that compared with the traditional protection scheme, the proposed protection method can protect the entire line reliably and has good tolerance to high transition resistance. Hence, the proposed method has promising prospects for engineering applications.","PeriodicalId":252797,"journal":{"name":"2022 4th Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127452777","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}

A decentralized approach based on the consensus alternating direction method of multipliers algorithm is proposed to achieve agreement on the price and quantity of trading between different microgrids.

Since the traditional power point prediction method cannot describe their uncertainty well, interval prediction can provide more comprehensive and valuable decision information for the operation of the power system. Based on this, a non-parametric kernel density estimation method without pre-assumption model is used to analyze the probability distribution characteristics of renewable energy output and load demand. The probability distribution curves are also fitted by this method, and then confidence intervals at different confidence levels are derived. Using the photovoltaic (PV) data as an example, the PV probability density function is calculated and the probability distribution curve is fitted to obtain the output prediction intervals at different confidence levels. The prediction interval coverage probability is used as an evaluation index of interval estimation to analyze and measure the effect of modeling estimation of renewable energy output and load demand.","PeriodicalId":252797,"journal":{"name":"2022 4th Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"18 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114036046","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}

The data-driven model consists of several intelligent algorithms that can estimate battery SOC using data acquired from pre-defined quick tests.
