【摘要】：虚拟电厂(virtual power plant,VPP)是聚合分布式发电、分布式储能及需求响应等分布式能源(distributed energy resources,DERs)进行统一管理并参与电力市场的有效技术形式。而VPP的功率不确定性问题不仅对其内部运行提出了挑战而且对提供给系统良好服务构成威胁。通过分析VPP市场合同实施、随机发电出力和可中断负荷响应的功率不确定性,建立了相应奖惩机制,即市场合同违约惩罚机制、弃风弃光惩罚机制和可中断负荷响应奖惩机制。基于奖惩机制,兼顾VPP运行经济和风险效益,制定了VPP协调调度策略。以VPP净利润最大为目标,兼顾系统运行约束,建立了奖惩机制下的VPP优化调度模型。通过对改进IEEE30系统算例仿真,验证了所提模型的有效性。
[Abstract]:Virtual power (VPP) is distributed power generation. Distributed energy resources and DERs, such as distributed energy storage and demand response, are effective forms of technology for unified management and participation in the electricity market. The power uncertainty of VPP not only challenges its internal operation but also provides. Good system services pose a threat. By analyzing the implementation of VPP market contracts, Based on the power uncertainty of random power generation and interruptible load response, the corresponding reward and punishment mechanisms are established, that is, the penalty mechanism of market contract breach, the penalty mechanism of abandonment of wind and light, and the reward and punishment mechanism of interruptible load response, which are based on the mechanism of reward and punishment. Considering the running economy and risk benefit of VPP, the coordinated scheduling strategy of VPP is formulated. Taking the maximum net profit of VPP as the goal and considering the system operation constraints, the optimal scheduling model of VPP is established under the mechanism of reward and punishment. The simulation of the improved IEEE30 system is carried out. The validity of the proposed model is verified.
