Analysis of a PV Power Plant in an Underloaded Power Network
This paper examines the operation of photovoltaic power plants (PVPP) in lightly loaded distribution networks, addressing stability challenges due to voltage and frequency fluctuations. Using DIgSILENT PowerFactory simulations, the study analyzes load profiles and PVPP interactions under low demand conditions. Results indicate that PVPP can induce overvoltage, voltage dips, and reactive power losses, reducing system efficiency. Optimization strategies, including advanced voltage and frequency regulation, are proposed to enhance stability. Findings emphasize the importance of proper PVPP controller tuning for reliable integration of renewables. Future work should explore network digitalization for improved flexibility and resilience.
