Research on voltage regulation control strategy for DC voltage offset minimization in DC distribution network
摘要
Abstract
The voltage control strategy of DC distribution network is analyzed and studied,and a new integrated voltage regulation control strategy based on the minimum DC voltage deviation is proposed in this paper.The primary voltage regulation responses to power fluctuations on real-time and quickly,which is controlled by DC voltage droop.The secondary voltage regulation periodically calculates and updates the voltage reference value and the power reference value of the droop controller by the power flow optimization algorithm when the total DC voltage deviation is the least,eliminating and reducing the voltage deviation caused by primary voltage regulation,preventing the occurrence of overvoltage when large power fluctuation occurs in DC distribution network.Finally,a four-terminal ring structure of DC distribution network simulation model is established on Matlab/Simulink.The simulation results validate the effectiveness of the proposed control strategy.关键词
