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.
