基于无功功率裕度分配的光伏电站静态无功/电压控制策略
A Static Reactive Power and Voltage Control Strategy of Photovoltaic Power Plant Based on Reactive Power Margin Distribution
摘要
Abstract
The operation of large-scale grid-connected photovoltaic (PV) power plants may cause the voltage fluctuation issue,which will affect the stable operation of power system.In order to reduce the adverse effects on the system safety and stability and the power network loss caused by PV plants,this paper investigates the reactive power and voltage control of PV plant.Firstly,we analyze the effect of active and reactive power on voltage of interconnection point.Secondly,we propose a reactive power and voltage control strategy for PV plant based on reactive power margin distribution.At last,we establish a real PV plant grid integration system model,and prove the feasibility and correctness of the proposed control strategy by dynamic simulations.关键词
