Voltage Stability and Regulation Strategies of Large-Scale Centralized Photovoltaic Power Plants
With the rapid development of renewable energy,large-scale centralized photovoltaic power plants have been widely deployed globally.However,the intermittency and variability of photovoltaic power generation may lead to voltage stability issues after integrating into the grid.This study focuses on addressing the voltage fluctuation and stability issues that may arise after the integration of large-scale centralized photovoltaic power plants into the grid.Through an in-depth analysis of the intermittency characteristics of photovoltaic power generation,system impedance characteristics,and control strategies of photovoltaic inverters,a series of targeted optimization strategies are proposed.These strategies include upgrading regulation equipment to improve response speed and adjustment accuracy,optimizing regulation strategies and algorithms to better cope with the dynamic changes of the grid,and envisioning future technological trends such as intelligent technology and data-driven voltage control methods.The aim is to enhance the stability and reliability of photovoltaic power generation systems and promote the wider application of renewable energy in power systems.
