Impacts of integration of very large‐scale photovoltaic power plants on rotor angle and frequency stability of power system

The increase in penetration of large-scale renewable generation significantly affects power system characteristics. Thus, it is necessary to assess the steady state and dynamic performance a for different installing scenarios plants such as photovoltaic (PV) ones. paper specifically investigates impacts very (VLS-PV) on including rotor-angle frequency stabilities. For this purpose, detailed equivalent model multi-unit VLS-PV corresponding controllers are developed. also proposes comprehensive set replacement comprising PV penetration, location, voltage control strategies well simulating various large disturbances. To investigate performance, study framework stability involving modal transient analysis presented well. By using along with other components synchronous generators, automatic regulators (AVRs), governors, stabilities studying instructions employed IEEE 39-bus 118-bus test systems.
