风电爬坡事件多级区间预警方法
Multi-level Early Warning Method for Wind Power Ramp Events
摘要
Abstract
Large-scale wind power ramp events (WPRE) have a significant impact on the power balance of power system and may lead to load shedding in severe cases.Interval analysis method is introduced to establish a multi-level early warning method for WPRE, by which the warning information can be provided to reflect the degree of potential harm inflicted by WPRE.According to the characteristics of WPRE, the number of intervals is introduced to describe the uncertainty of wind power.In view of the impact of large volatility of WPRE on power control and with the static frequency deviation maintained within the allowable range as precondition, the permissible intervals of ramping amplitude are analyzed to determine the boundaries between different warning levels corresponding to different power control measures.Comparison of the boundaries with the prediction results of wind power, multi-level early warning for WPRE shows that the interval ranking method can provide the probability distributions of different warning levels.Simulation results and comparative analysis demonstrate that, both the boundaries and probability distributions of different warning levels, with clear physical meaning, can be provided by the simple and rapid method beneficial to real-time scrolling operation and testifying to the effectiveness and practicability of the proposed method.关键词
