为更好地发挥虚拟电厂（VPP）区域资源优化配置和新能源消纳能力,提出一种支撑高渗透率区域平衡的虚拟电厂动态分区调度决策方法。首先,考虑各边端台区负荷变化特征,利用K-均值聚类++聚类算法,从数据特征距离入手,以分区间的线路交互容量最小为目标,对边端进行小时级滚动分区。其次,结合边端台区上传的供用电数据与日内滚动小时更新的购售电价格,以VPP下属合作博弈区域内部消化交易优先为目标的同时,嵌套VPP和下属区域主从博弈,以下属区域利益最大化和VPP整体运营成本最低为目标,建立电力市场博弈策略模型。最后,基于改进IEEE62节点系统,对3种不同方案对比仿真,验证所建模型达到VPP整体运营成本降低、下属分区分布式新能源利用率增长和对外传输线传输容量降低的效果。
Abstract
The integration of a large number of distributed energy resources to high-permeability regional power grids makes it more difficult for station areas to achieve self-management and interact with supply and demand. In order to optimize the allocation of regional resources and improve the capacity for new energy consumption in virtual power plants （VPPs）, this paper proposes a dynamic partitioning decision-making method to support the regional balance in high-permeability areas. Firstly, considering the load change characteristics of each edge station area, using the K-means++ clustering algorithm is used based on data feature distances, with the goal minimizing the transmission line capacity between partitions, and performing hourly rolling partitioning to distinguish the edge stations. Secondly, combined with the supply data uploaded by the edge station area and the hourly updated purchase and sale prices, a power market game strategy model is established with the goal of prioritizing digestion and transaction within the subordinate cooperative game area of VPP. Additionally, the master-slave game between VPP and subordinate regions is nested to maximize the interests of subordinate regions and minimize the overall operating cost of VPP. Finally, based on the improved IEEE62 node system and a comparison of the simulations of three different schemes, it is verified that the model achieves the effect of reducing the overall operating cost of VPP, increasing the utilization rate of distributed new energy in subordinate partitions, and reducing the transmission capacity of external transmission lines.
