摘要(Abstract)：

风光水互补发电系统中,积极利用需求侧的数据中心参与响应,在平衡风光间歇性出力、减轻水电机组调节压力以及提高源端经济效益等方面能够产生明显效果。数据中心作为高能耗负荷类型,能耗峰谷差大,资源分配和数据处理方式灵活,减少一定的用户满意度将有效地实现电量需求转移。根据批处理负荷区间性处理要求,提出数据中心对工作负荷的并发处理模式,在此基础上,计及IT设备处理能耗、空调散热能耗以及网络通信能耗3类主要电力消耗,建立数据中心资源分配、延迟决策与能耗转移模型。针对梯级水电之间出力、流量、水头等相互约束关系,并计入风光的不确定性,制定以经济效益、负荷追踪系数及风光消纳程度的多重目标,建立含风、水、光的多能互补发电端与负荷端数据中心的优化调度模型。最后通过算例仿真得到在不同季节、天气和时段下风光水的最佳出力及数据中心的最小负荷转移量,验证了所提方法的有效性和正确性。
