Hybrid Predictive Control of Capacitor Voltage Balance Based on Modular Multi-level Converter
摘要
Abstract
A hybrid control method for balance control of the sub-module capacitor voltage based on multi-level converter module (MMC) is proposed.According to state of the sub module and current of the converter bridge,the predictive value of the sub-modules capacitor voltage in the next action cycle is obtained.Taking the predictive absolute error limit of the capacitor voltage as the voltage deviation criterion,the sub-modules switching on/off scheme for the next action cycle is obtained.Proposed method can guarantee the balance of sub-modules capacitor voltage as well as the low switching frequency.In the end,11-level MMC system is built in the PSCAD / EMTDC,and the simulation results verify the effectiveness of the proposed method.关键词
