计及价格型负荷响应过程的连续性概率潮流分析方法

摘要

在建立了价格型负荷时序概率模型的基础上，提出了计及响应过程并利用灵敏度修正的连续性概率潮流分析方法。该方法能有效反映价格型负荷的响应过程，计算结果更符合实际电网的运行情况，并能为评估整个响应过程的合理性提供依据。以某省级电网为例，进一步验证了连续性概率潮流分析的必要性。%Following the development of a timing probability model for the price-based load, a method of continuous probabilistic load flow analysis considering the response process and rectified by sensitivity is proposed.It is shown that the method can not only effectively reflect the response process of the price-based load but also capture and filter out security problems of the grid ahead while providing a basis for assessment of the rationality of the entire response process.The necessity of continuous probabilistic load flow analysis is further validated with a provincial grid simulation results.
