摘　　要：随着电网调管水电规模的扩大以及调度精细化的需求,如何考虑不同电站调节性能差异进行精细化调峰,使得火电平稳运行,减少参与深度调峰,成为电网短期水电调度亟需解决的关键难题。针对电网短期精细化调度问题,提出了在水电站群调峰优化调度模型中考虑各水电站调峰性能差异的差异化调峰优化模型,更好地利用水电的调节能力,使得短期调度计划编制更加准确、合理。依照电网所辖水电站的调节性能不同划分弱调峰电站、调峰电站以及平衡电站进行差异化约束处理,并采用关联搜索方法对差异化调峰优化模型进行求解。选取广西37座水电站进行实例验证,结果表明:对比传统调峰优化模型,差异化调峰优化模型考虑了不同水电站调节性能的差异,进一步降低系统剩余负荷的峰谷差,平抑剩余系统负荷波动并调平系统负荷微小和频繁波动,是一种满足实际工程需求的精细化调度方法。The scale of regulated hydropower in the power grid and the demand for refined dispatch continue to expand.How to carry out refined peak-shaving considering the differences in the regulatory performance of different power stations,which makes thermal power run smoothly and reduces the depth of participation in peak shaving,is the key problem to be solved in short-term hydropower dispatch of the power grid.To deal with the refined short-term scheduling of some provincial power grids,this paper proposes a peak-shaving optimization model of hydropower station groups considering peak-shaving performance differences.The model makes the short-term scheduling plan more accurate and reasonable and can better use hydropower regulation capacity.According to the different regulatory performance of the hydropower stations under the power grid,the paper conducts differentiated constraint processing to the weak peak-load station,the peak-load station,and the balanced power station.In addition,the successive associated search method is applied to solve the differentiated peak load optimization model.A total of 37 hydropower stations in Guangxi power grid are selected for the case study.The results show that compared with the traditional model,the differential peak-shaving optimization model takes into account the difference in regulation performance of different hydropower stations.It further reduces the peak-valley difference of the residual load of the system,smooths the fluctuation of the residual load of the system,and levels the small and frequent fluctuations of the system load,which is a fine scheduling method to meet the actual engineering requirements.
