Moreover, a series of harmonic currents and unbalanced load currents are affecting the power quality seriously. The active power filter is mainly used to compensate the harmonic current. However, the compensation effect is affected by the dynamic response speed of harmonic current detection. In this paper, the FBD(Fryze-Buchholz-Dpenbrock) theory and its derived harmonic detection method, and the deficiency in dynamic response of the low-pass filter and the Moving Average Filter (MAF) are introduced and analysied, respectivly. Then, an improved Generalized Moving Average Filter (GMAF) is proposed to improve the dynamic response speed of harmonic detection. Finally, based on FBD power theory, a single-phase and three-phase simulation model is built in MATLAB/Simulink, and the simulation results of two methods under steady state and load current mutation are given, and the characteristics of GMAF’s dynamic response speed are verified.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124240786","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}

Uncertainty, a ubiquitous and challenging problem in the high penetrated renewable energy system, is considered in the microgrid system. Also, the security constraints of the energy transmission between microgrids are introduced. The objective of the networked microgrids is to maximize the day-ahead social welfare by cooperating with each other. To this end, the problem is formulated as a class of robust distributed coupled optimization problem. Following, an affinely adjustable-based robust distributed optimization method with event-triggered communication is proposed to address this issue. With the effort, each microgrid can determine its owing optimal operations through only local communication and computation, resulting in enhanced system reliability, scalability, and privacy, and as well as reduced communication. Simulations are provided to verify the effectiveness of the proposed method.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123467410","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}

Hence, in order to extent the proportion of solar energy in power grid, a method for controlling ramp-rate is necessary to be installed in PV system. Normally, energy storage system (ESS) is employed without a direct control and controllable ramp-rate in prior-arts. Meanwhile, the state of charge (SoC) of ESS could also influence the fluctuation mitigation performance. In this paper, an adaptive ramp-rate control is proposed with integrated ESS for fluctuation mitigation. This control blends a direct ramp-rate control to reduce the fluctuation caused by PV side irradiation change to a desired level and a SoC control with variable ramp-rate to improve the performance in unexceptional SoC. The proposed control is verified by the simulations based on a typical PV micro-grid with ESS.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114794070","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}

Typical characteristics of UAV attack on power grids are analyzed and summarized in five aspects: difficult to be detected, hard to be foiled, nonsensitive, clustered and precise. To illustrate the feasibility of UAV attack, UAV short-circuit attack mode is proposed as an effective way to attack against the grid. We analyze the feasibility of UAV short-circuit attack mode by establishing a mathematical model, and verify the feasibility based on various short-circuit materials. UAV frequency attack strategies are discussed to show the severe damage inflicted by UAV attack. Among them, Multipoint Multistage Attack (MMA) strategy can result in rapid collapse of the frequency by implementing a series of attacks precisely. Compared to Multipoint Simultaneous Attack (MSA) strategy, the MMA strategy can utilize both the characteristics of UAVs and vulnerability of system frequency. The proposed strategies are evaluated by a dynamic frequency simulation model. Simulation results show the effectiveness and advantages of the UAV frequency attack strategy.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128061633","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, this paper summarizes four typical DC fault handling configurations including the DC circuit breaker (DCCB), the hybrid MMC with full bridge submodules and half bridge submodules (FHMMC), the LCC-MMC hybrid configuration with diode groups installed in the DC line close to the converters (LCCD-MMC) and the hybrid topology with an LCC and an MMC in series-connection. Then the basic structures and DC fault clearance schemes of the four configurations are discussed. Finally, a three-terminal simulation system is established to compare the DC line fault transient characteristics of the four MMC-HVDC configurations. The simulation result shows that the DCCBs perform the best DC fault clearance characteristics. Considering the cost efficiency and operation flexibility, the LCC-MMC hybrid topology has certain value of practical application in engineering.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128116548","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}

One part is caused by the inconsistent recovery time of inverters at different power levels during low voltage ride-through (LVRT), and the other is attributed to the different dominant dynamics of the inverters. According to these two sources of error, a two-step clustering method is proposed and implemented in a 36-inverter system. The simulation results show that this method has higher precision in different scenarios, but it is accompanied with the sacrifice of simulation speed.
