摘要:
将工业园区内部多元化灵活可调资源聚合为园区虚拟电厂,可充分挖掘工业园区的需求响应潜力,提高自身收益。为优化电碳联合市场背景下的园区虚拟电厂需求响应策略,提出了考虑碳排放成本的园区虚拟电厂日前-日内两阶段优化调度模型,并采用GAMS软件求解。日前阶段,采用改进径向基函数神经网络进行光伏发电功率预测,并以需求响应净收益最大为优化目标,确定需求响应投标容量。日内阶段,根据光伏实时出力,以运行成本最小为优化目标对日前调度计划进行修正,尽可能减少日前光伏出力预测误差对需求响应收益的不利影响。最后,对某园区虚拟电厂进行仿真分析,结果表明:所提策略可在计及碳排放成本前提下,最大化园区虚拟电厂参与需求响应获取的净收益。
