【摘要】：提出一种包含调整机组优化选取策略的滚动优化调度方法。根据负荷及风电超短期预测信息,首先考虑等效负荷(负荷+风电)预测偏差和机组调节容量匹配、机组爬坡量和等效负荷波动量匹配,以及减少外送断面越限原则进行调节机组优化选取。在此基础上,以机组调整成本及弃风量最小为目标,建立优化模型并采用改进粒子群优化算法求解。实际算例表明,考虑机组优化选取的滚动优化调度实现了超短期时间尺度上对负荷及风电预测偏差的自动跟踪调节,提高了发电计划的准确性,同时有效降低了综合发电成本和外送断面功率越限的风险,提高了电网运行的经济性和安全性。
[Abstract]:This paper presents a rolling optimal scheduling method which includes the optimal selection strategy for adjusting units. According to the ultra-short-term forecasting information of load and wind power, the matching of forecasting deviation of equivalent load (load wind power) and unit regulating capacity, the matching of unit climbing and equivalent load fluctuation are first considered. And the principle of reducing the outputting cross section to optimize the selection of regulating units. On this basis, the optimization model is established and the improved particle swarm optimization algorithm is used to solve the problem. A practical example shows that the rolling optimal scheduling considering the optimal selection of generating units realizes the automatic tracking and adjusting of load and wind power forecasting deviation on the ultra short term time scale, and improves the accuracy of power generation plan. At the same time, it can effectively reduce the risk of comprehensive generation cost and outputting cross section power, and improve the economy and security of power grid operation.
