DC Bus Voltage Stability Control of Photovoltaic Power Generation Supercapacitor Energy Storage Grid Connected System
During the grid connected operation of photovoltaic power generation systems,due to continuous changes in light intensity and fluctuations in load demand,the DC bus voltage is prone to instability.This voltage fluctuation not only affects the stability of the entire system,but also has adverse effects on power quality.To effectively solve this problem,a supercapacitor energy storage system is introduced as an energy buffering device,which can release energy when the light intensity decreases or the load demand increases,and store energy when the light intensity increases or the load demand decreases,thereby effectively stabilizing the DC bus voltage.This article will explore in detail the DC bus voltage stability control strategy of supercapacitor energy storage grid connected systems,analyze their working principles and control methods,in order to provide effective solutions for the stable operation of photovoltaic power generation systems.
