Abstract

In order to evaluate the risk of wind power curtailment and loss of load brought by wind power ramp event on power system, risk assessment model of wind power ramp event based on Monte Carlo method is established. According to the result of wind power prediction system, the wind power model of day-ahead positive and negative wind power ramp event is established. Several constraints need to be satisfied during the evaluation process. Risk indicators like expectation of wind power curtailment, loss of load expectation, times of loss load expectation and off-limit risk indices of line power flow are calculated during the process of risk assessment. A specific algorithm flow of risk assessment is also given in this article. Finally, the validation of the proposed method is verified in IEEE-RTS79. The simulation results demonstrate variation trend of risk indicators under different amplitude, start time and duration of wind power ramp events, and indicate the weak spot of power system under the circumstance of wind power ramp event.
