Abstract

Abstract: With the development of UHV AC/DC power system, the security and stability characteristics are becoming more and more complex, preventive controls are needed to reduce the accident risk of multiple serious faults. For security and stability problems with low real-time requirement (minute level), timely post-fault manual emergency regulation measures can avoid the high cost of preventive control. In order to remedy the defects of offline manual emergency regulation plans and real-time decision calculation of corrective control, an online pre-decision-making method of manual emergency regulation is proposed in this paper. Based on medium and long term time domain simulation method with variable step size, the quasi-steady operation state is determined by amplitude of frequency fluctuation, and the pre-decision-making strategy is obtained by solving the optimization function with steady state security constraints. The manual emergency regulation is carried out after real fault through pre-decision-making strategy of matching the types of fault and security problem. The validity of the method is verified by a case study of the actual power system.

Key words: online assessment, security and stability, pre-decision, emergency regulation, comprehensive defense
