计及风险约束的虚拟电厂能量管理建模
Risk-constrained Energy Management Modeling of Virtual Power Plant
摘要
Abstract
Large-scale distributed energy resources integrated into the distribution network inevitably increase the operation complexity of power systems.Virtual power plant as a new operating mode,which is based on decentralized management,can effectively integrate different types of distributed energy resources.Uncertainties involved in the virtual power plant such as stochastic generators' output and power market purchasing strategies often bring risk to the decision making of virtual power plant operation.Based on the comprehensive modeling of the dispatching units,stochastic generators,energy storage devices and flexible loads,a two-stage stochastic energy management model of the virtual power plant considering the conditional value-at-risk was established.The objective is to maximize the profit of the virtual power plant while the risk imposed by the uncertainties is restricted to a predefmed level.Through the simulation on a virtual power plant,the effects of different risk appetite on the virtual power plant participating in power market and the process of energy management were discussed,which can provide the operator with valuable guidelines for the operation of the virtual power plant.关键词
