基于分布式共识协同的光伏逆变器电压控制策略研究
Voltage control strategy for a PV inverter based on distributed consensus collaboration
摘要
Abstract
To solve the voltage limit problem caused by large-scale distributed photovoltaic(PV)connecting to the distribution network,a voltage control method of PV inverter based on distributed consensus collaboration(DCC)is proposed.The PV inverter voltage control adopts a sag control mode based on power regulation,using sag control to regulate the active and reactive power of the PV to achieve the control of the PV grid voltage.Distributed cooperative consensus is to use the active power output of the PV connected to the system and the PV maximum output tracking ratio as state variables,and to implement the adjustment of the sag control start-up parameters and the voltage cooperative control between PV inverters through the distributed consensus cooperative algorithm.Arithmetic verification is carried out with a real feeder system with distributed PV,and simulation is made based on DIgSILENT software.The results show that the proposed voltage control method can effectively suppress the voltage crossing problem of PV parallel networks and reduce the reduction of PV active power output in the voltage regulation process,and improve the reactive power regulation of PV inverters.关键词
