Abstract
水电站跨省跨区送电涉及多省份、多品种、多时间尺度等多维度电量曲线分解,且需要考虑复杂的电网调峰等需求,是电站每月发电运行中亟待解决的重要难题。依托实际工程的生产需求,构建了适合跨省、跨区送电的水电站月度合同电量曲线分解模型,考虑保量保价、保量竞价、市场化三类品种电价差异,以及电网调峰、市场和电站运行复杂约束,提出了多省多品种发电收益总和最大的二次规划目标,并采用混合整数线性规划方法实现了模型高效求解。以溪洛渡右岸水电站为依托工程,通过枯期、汛期两个不同的应用场景进行了模型验证,结果表明在满足电网要求的调峰边界条件下,通过优化两省多尺度多品种电量和出力分配,市场化电量优先分配至负荷高峰和平段,可以有效提高电站发电收益
