Abstract

Disturbance to the electric power system often occurs with different impact. Those power system disturbances cannot be avoided but it can be mitigated by having a premeditated action which refers to the risk assessment. This paper presents the bootstrap technique that used to assess the risk of a power system at every uncertainty level of system states and load variations. In addition, the risk based uncertainty assessment is determined when the load is increased by 20%, 40% and 60% from the base case condition. The effectiveness of bootstrap technique in risk based uncertainty assessment is tested on a case study of 24-bus IEEE Reliability Test System (RTS).

考虑负荷需求增加的电力系统风险不确定性
电力系统经常受到干扰,影响程度不一。这些电力系统的干扰是无法避免的,但可以通过有预谋的行动来减轻,这涉及到风险评估。本文介绍了一种用于评估电力系统在系统状态和负荷变化的各个不确定水平上的风险的自举技术。此外,在负荷比基准情况增加20%、40%和60%时,确定了基于风险的不确定性评估。以24总线IEEE可靠性测试系统(RTS)为例,验证了自举技术在基于风险的不确定性评估中的有效性。
