Grid Voltage Stabilization with Single-Node Centralized PV Power Access
Based on the analysis and simulation of the impacts on grid voltage caused by the distributed PV power generation with single-node centralized access,this paper explores into the immediate relationship of PV line voltage with the access node distanc,circuit parameters,PV power generation and load.The grid access node voltage can be adjusted by controlling the magnitude and direction of the active and reactive power of the PV grid connected inverter,finally realizing the system voltage control.The active and reactive voltage regulator is employed to realize the voltage control of regional distributed PV system.The methods for selecting the access node and controlling voltage of the distributed PV system are proposed with a view to improving power quality,reducing power consumption,and saving additional cost on compensation equipments.
