In the process of photovoltaic grid connection, a multi-objective control strategy is proposed, in which the three-phase network controller simultaneously controls the harmonic and realizes the reactive power and current balance. The [Formula: see text], [Formula: see text] current detection method, which is based on the current reactive power characteristic theory, can detect the compensation current. In order to reduce the measurement error of PLL, a software PLL based on decoupled double synchronous reference coordinate transformation is introduced, and the principle of multi-objective rule of three-stage network inverter is also given. The simulation and test results show that the harmonic distortion rate decreases from 2.57% to 1.10% with the proposed strategy, and the unbalance between reactive power and current is compensated, which verifies the correctness and feasibility of the strategy. <\/jats:p>","DOI":"10.1142\/s0218126622502309","type":"journal-article","created":{"date-parts":[[2022,4,28]],"date-time":"2022-04-28T10:23:06Z","timestamp":1651141386000},"source":"Crossref","is-referenced-by-count":2,"title":["A Multi-Objective Current Compensation Strategy for Photovoltaic Grid-Connected Inverter"],"prefix":"10.1142","volume":"31","author":[{"given":"Shengqing","family":"Li","sequence":"first","affiliation":[{"name":"School of Electrical and Information Engineering, Hunan University of Technology, Zhuzhou City, 412007, Hunan Province, P.\u00a0R.\u00a0China"},{"name":"Hunan Engineering Research Center of Photovoltaic, Micro-Grid Intelligent Control Technology, Zhuzhou, 412007, Hunan, P.\u00a0R.\u00a0China"}]},{"given":"Zhijian","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Electrical and Information Engineering, Hunan University of Technology, Zhuzhou City, 412007, Hunan Province, P.\u00a0R.\u00a0China"},{"name":"Hunan Engineering Research Center of Photovoltaic, Micro-Grid Intelligent Control Technology, Zhuzhou, 412007, Hunan, P.\u00a0R.\u00a0China"}]},{"given":"Wang","family":"Han","sequence":"additional","affiliation":[{"name":"School of Electrical and Information Engineering, Hunan University of Technology, Zhuzhou City, 412007, Hunan Province, P.\u00a0R.\u00a0China"},{"name":"Hunan Engineering Research Center of Photovoltaic, Micro-Grid Intelligent Control Technology, Zhuzhou, 412007, Hunan, P.\u00a0R.\u00a0China"}]}],"member":"219","published-online":{"date-parts":[[2022,5,20]]},"reference":[{"key":"S0218126622502309BIB001","first-page":"27","volume":"37","author":"Zhao M.","year":"2017","journal-title":"Proc.
