However, most researches on the CV ignore the hybrid generation system based on multiple complementary energy resources, as well as the operation strategy of energy storage system (ESS). To solve these problems, the models of available capacity of ESS are developed based on three different strategies. Then, using the sequential Monte-Carlo simulation method, the models and methods are developed for reliability assessment of generation system and capacity value estimation for the hybrid power generation system based on WT/PV/ES (HGS-WPE).

Therefore, this paper proposes a novel real-time estimation method for fault currents of distributed generations. Considering the low voltage ride through (LVRT) control strategy, the fault equivalent model of inverter-interfaced distributed generation (IIDG) is established firstly. Besides, a method for calculating the positive-sequence voltage at the point of common coupling (PCC) is put forward. Then, based on the electric information including current and voltage at both sides of the feeder, a real time estimation method for fault current of IIDGs is proposed. The accuracy of the proposed method is verified by a 10kV distribution network with multi-IIDGs established in PSCAD/EMTDC at last.","PeriodicalId":231527,"journal":{"name":"2016 China International Conference on Electricity Distribution (CICED)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126195789","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}

This paper introduced a dual PWM inverter to reduce AC voltage harmonics when DC voltage was changing, which is based on D&T's inverter model. Dual PWM inverter is composed of two series three-phase PWM inverters. Its fundamental voltage characteristic is used to calculate modulations to maintain output voltage stably, and its harmonic voltage characteristic is used to calculate the operating point for harmonics minimization. Therefore, the two series inverters worked with different modulations, but its total output voltage is constant, and the harmonic distortion rate is at low level.

Based on the theoretical derivation that the voltage and current variation at a node are taken as the superposition of the variations respectively caused by the system side and the load side, a new mathematical model that takes into account the variable at the system side is built. Independence of variables at the system side and the load side is used to solve the model. Compared with the existing methods, the proposed method doesn't assume that the equivalent source voltage is constant, so it is more applicable to the situation when persistent disturbances occur at the system side. Simulation and filed tests show that the proposed approach performs better than the least square method when the persistent disturbances occur at the system side. With the persistent disturbances becoming larger, the least square method doesn't work gradually, while the proposed approach can identify the parameters of the Thevenin equivalent circuit as well.","PeriodicalId":231527,"journal":{"name":"2016 China International Conference on Electricity Distribution (CICED)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115343876","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}
