摘要
随着电网向高压、远距离、大容量发展,对电网安全性要求日益显著,传统的N-1准则下可靠性计算已不能完全满足可靠性评估的要求。蒙特卡洛算法是一种概率随机抽样方法,利用该方法模拟系统状态,建立了参考状态序列,设计新的状态,并同参考状态比较,更加全面地反映系统压力和可靠性裕度,并利用期望缺供电量EENS作为可靠性指标来对系统的可靠性进行分析。
As the power grid grows to be of high-voltage, long-distance and high-capacity, requirements for the safety of the grid are increasingly significant, therefore the traditional N-1 criterion reliability calculation can not fully meet the requirements of the reliability evaluation. The Monte Carlo algorithm proposed in the paper is a random probability sampling method used to simulate the system state and to establish the reference state sequence. The method can be used to design a new state for comparison with the reference state. It can fully reflect the system pressure and reliability margin. EENS can serve as a reliability indicator in this paper to analyze the power system reliability.
