Although existing literatures have applied virtual impedance to VSG, aiming for suppressing overcurrent, rare papers mentioned how to meet the standards that the inverters output sufficient reactive power to power grid for low voltage ride-through (LVRT) strategy of VSG at the same time. In this paper, a quantitative design method of virtual impedance for LVRT strategy of VSG is proposed. In the LVRT strategy, the power loop is frozen first; then, the virtual impedance calculated by the proposed method is added to ensure the safe and stable operation during the voltage sags. The hardware-in-the-loop experimental results show that with the quantitatively designed virtual impedance, the overcurrent is avoided and the requirement of gird code for reactive current support is satisfied simultaneously, verifying the correctness and feasibility of the proposed quantitative design method of virtual impedance.","PeriodicalId":356667,"journal":{"name":"2021 3rd Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131305520","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 short-term load forecasting model based on EEMD- LN-GRU is proposed according to the characteristics of uncertainty and nonlinearity of power load. In order to solve the problem of power load fluctuation and mode aliasing caused by empirical mode decomposition (EMD), the original load time series signal is decomposed into multiple intrinsic mode functions (IMF) and residual error component by ensemble empirical mode decomposition (EEMD). Each component signal is predicted by the gating recurrent unit (GRU) after layer normalization (LN). Finally, the components are predicted. The results are recombined, and then the peak valley value of the prediction sequence obtained by peak valley value correction strategy is modified to obtain the final load series. Taking the real load data of power plant of Slovak power company as an example, this method is compared with LSTM, GRU and other methods, and the results show that the proposed method has higher prediction accuracy for load forecasting.","PeriodicalId":356667,"journal":{"name":"2021 3rd Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129741697","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}
