基于多狀態(tài)新能源發(fā)電模擬的日運行方式及調(diào)峰安排研究
[Abstract]:The access of large-scale wind power makes the peak-shaving problem of power system more and more serious, so it is necessary to study the rationality of power supply structure by analyzing the daily operation mode. Based on the traditional power balance method, a daily operation mode and peak-shaving algorithm based on multi-state new energy generation simulation are proposed, which can be used to analyze and verify the operation feasibility of the power supply scheme. The algorithm is based on the Markov process to model the wind power output in time series. According to the historical wind power output data, the initial distribution and transfer matrix are obtained. Based on the equivalent power function method, an efficient multi-state load correction method is proposed, and then the power balance and peak load regulation of the system are studied by deterministic production simulation method. In order to ensure that the power construction scheme to meet the economic reliability on the basis of the operational feasibility of the relevant requirements. The effectiveness and practicability of the proposed model and algorithm are verified by an example, which can be used as a reference for power planning in China.
