Analysis Of The Influence Of Large-Scale Integration Of Centralized Energy Storage Into The Power Grid On Voltage Security And Stability Of Power System

With the increasing proportion of renewable energy power generation in the power system, the influence of renewable energy power generation on the security and stability of power system can't be ignored. As the "lubricant" in power system, energy storage technology has played a positive role in peak load regulation, frequency regulation, voltage regulation and emergency standby. Based on PSASP simulation software, this paper studies the influence large-scale integration of centralized energy storage into the power grid on voltage security and stability of power system. The simulation results show that large-scale energy storage access can alleviate the problem of grid voltage stability, but there may be a risk of transient overvoltage.
