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).
