【摘要】：大规模风电的接入使得电力系统的调峰问题越来越严重,因此有必要通过分析日运行方式来研究电源结构的合理性。在传统电力电量平衡法的基础上,提出了一种基于多状态新能源发电模拟的日运行方式和调峰安排算法,用于对电源投产方案进行运行可行性的分析与校验。算法基于Markov过程进行风电出力的时序多状态建模,根据历史风电出力数据得到初始分布和转移矩阵。在等效电量函数法的基础上提出了一种高效的多状态负荷修正方法,进而以确定性的生产模拟方法研究系统的电力电量平衡情况及调峰问题,从而保证电源建设方案在满足经济性、可靠性的基础上还满足运行可行性的相关要求。算例分析验证了所提模型与算法的有效性和实用性,可为我国电源规划工作提供参考。
[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.
