面向调度运行的电网安全风险管理控制系统(二)风险指标体系、评估方法与应用策略

Design of a Security Risk Management System for Power System Dispatching and Operation Part Two Risk Index,Assessment Methodologies and Application Strategies

对电网安全风险管理控制系统(SRMS)中风险评估功能的实现进行了详细介绍。建立了越限驱动型风险和事件驱动型风险相结合的指标体系,阐述了风险评估方法的流程,提出了风险指标体系在时间维度和空间维度的应用策略。文中最后给出了SRMS在湖南电网的应用算例。

This paper presents a detailed description of implementing the risk assessment function module for the power system security risk management system（SRMS）.First,a risk index hierarchy for violation driven risk indexes and event driven risk indexes combined is proposed.Then the calculating process of risk indexes and their application strategies for time dimension and spatial dimension are elaborated,respectively.Finally,numerical results of risk assessment in Hunan power system are given.
