摘要
需求侧响应是未来协调系统供需平衡的重要手段,电动汽车作为一类特殊负荷,鼓励其参与需求侧响应是提高用户响应水平以及提高系统运行经济性的有效途径。鉴于此,该文从微网运营商的角度出发,在考虑可再生能源出力以及负荷不确定性条件下,以系统运行成本最小为目标构建了适用于不同需求侧响应策略的电动汽车参与需求侧响应调控策略随机优化模型。在IEEE-6节点配电网系统中对上述模型进行了仿真,结果显示,电动汽车参与需求侧响应能够有效减少系统运行总成本,其中实施基于激励的响应机制具有更好的经济效益。
Demand side response is an important means to balance supply and demand of the system in the future. As a kind of special load,promoting electric vehicle to participate in demand response is an effective way to improve response level of users and the economy of system operation. In view of this, from the perspective of micro-grid operators,considering the uncertainty of renewable energy output and load,this paper constructs the stochastic optimization model for demand side response control strategy with electric vehicles under different demand side response strategies,aiming at the minimum operating cost of the system. This model is simulated in IEEE-6 bus distribution network system. The results show that the participation of electric vehicles in demand side response can effectively reduce the total operating cost of the system,in which the implementation of the incentive based response mechanism has better economic benefits.
