Risk Evaluation of Security and Stability Control System for Renewal Energy Cluster

With the aim to better direct the design, implementation, and decision making in the security and stability system of renewable resource cluster, the efficiency function and coefficients of Security and stability control system (SSCS) were defined. Combined with the distribution function of the primary energy of SSCS, the system risk was analyzed quantitatively based on the Monte Carlo simulation. The SSCS of one 330 kV substation was used to verify the proposed model and methods; it was utilized in the analysis of the influences of risk evaluation result and generation shedding strategies, renewable resources scale, stability control threshold value, reliability parameters, and economic parameters.
