微电网双向变流器的复合控制策略
A hybrid control method for a bidirectional converter used in micro-grid systems
摘要
Abstract
The stability control and power quality improvement of micro-grid systems using a bidirectional converter is studied.In consideration of the fact that the traditional converters like dynamic voltage regulator (DVR), static var generator ( SVG) , active power filter ( APF) cannot be directly applied to micro grids due to the reasons of their dynamic response , power level and economy , a compound control method based on the nonlinear control theory is proposed .The method uses feedback linearization to control the inner current loop to turn the complex nonlinear system into a linear system , and fully decouples active and reactive current to improve the tracking precision and dynamic response of the inner current roop , and also improve fast response capability of the voltage outer loop; at the same time, it uses the sliding mode to control the voltage outer loop to solve the problem of time-varying param-eters and to improve the robustness and anti-interference of the outer loop voltage .The experiments show that this composite control method has the abilities of fast dynamic response , higher precision , smaller harmonic of the AC side current , and the DC side voltage has the fast dynamic response .关键词
