中文摘要：

针对电力市场中用户对实时电价的反应，本文提出一种计及实时电价的电力系统运行风险管理新策略。该策略在评估电力系统运行风险的基础上，对实时电价进行调节，并以电价为信号，刺激用户采取合理的用电结构和方式，从而增强电力系统运行的可靠性。该方法只是弥补了传统方法无法考虑系统运行可靠性的不足，而并非颠覆传统的电价管理方法，所以二者具有很好的衔接性。最后，通过对IEEPRTS测试系统的可靠性进行计算分析，验证了所提算法的有效性。

英文摘要：

Considering the reaction of customers in electricity market to spot price,a new strategy of operation risk management of power system is proposed. On the basis of operation risk evaluation of power system, the spot price of electricity can be adjusted based on this strategy. Through taking electricity price as the signal, stimulating consumers to adopt rational consumption structure and mode and enhancing the reliability of system operation can be implemented. The proposed strategy remedies the deficiency in conventional electricity price management rather than overthrows it,and there exists the splicing between these two methods. Finally,the effectiveness of the proposed strategy is verified through testing the reliability of IEEE-RTS79 system.
