摘要(Abstract)：

为促进以风光为代表的分布式能源发电并网,集成风电、光伏发电、燃气轮机、储能系统和激励型需求响应为虚拟电厂(virtual power plant,VPP),引入条件风险价值(conditional value at risk,CVaR)理论和置信度方法描述VPP运行不确定性,以运营收益最大化为目标函数,建立VPP常规调度优化模型,确定VPP运行收益的门槛值。然后,应用CVaR理论描述VPP运行目标函数中不确定性因素,应用置信度方法转换含不确定性变量的约束条件,建立考虑运行风险的VPP随机调度优化模型。最后,选择改进IEEE 30节点系统作为仿真系统,结果表明:价格型需求响应能够平缓用电负荷曲线,储能系统和激励型需求响应能够增加VPP运营收益。VPP常规调度收益为9 550.19元,风光并网电量为12.49 MW×h,风险规避调度收益为8 995.34元,风光并网电量为11.31 MW×h,这意味着CVaR理论和置信度方法能够用于描述VPP运行风险,通过设置门槛值和置信度反映决策者风险态度,为决策者提供风险控制工具。
