Abstract
As the use of wind power turbines increases worldwide, there is a rising interest on their impacts on power system operation and control. Frequency regulation in interconnected networks is one of the main challenges posed by wind turbines in modern power systems. The wind power fluctuation negatively contributes to the power imbalance and frequency deviation. Significant interconnection frequency deviations can cause under/over frequency relaying and disconnect some loads and generations. Under unfavorable conditions, this may result in a cascading failure and system collapse.
This chapter presents an overview of the key issues on frequency regulation concerning the integration of wind power units into the power systems. Following a brief survey on the recent developments, the impact of power fluctuation produced by wind units on system frequency performance is presented. An updated frequency response model is introduced, and the inertia contribution of wind turbine in the overall system inertia is properly considered. The need for the revising of frequency performance standards is emphasized, and an intelligent agent based load frequency control (LFC), using multi-agent reinforcement learning (MARL) is proposed. Finally, nonlinear time-domain simulations on a 39-bus test power system are used to demonstrate the capability of the proposed control structure, and to analyze the system frequency performance in the presence of high wind power penetration and associated issues.
