Multi-dimensional Quantitative Assessment of Interactive Regulation Capability for Virtual Power Plants Based on Hierarchical Aggregation
摘要
Abstract
Quantitative assessment of interactive regulation capability for a virtual power plant(VPP)serves as critical foundation for evaluating its regulation performance and optimal operation under diverse spatiotemporal conditions.To achieve a refined assessment of the regulation capability for a VPP,this paper proposes a multi-dimensional quantitative assessment method for VPP based on hierarchical aggregation.Firstly,a data-driven method is employed to address the requirements of market transaction decisions across various time scales.By applying the k-means algorithm to extract typical user load profiles,a quantitative assessment model is obtained for the regulation capability of single flexible resource,which incorporates an incentive price-based correction to account for realizable potential.Secondly,considering factors such as regulation capacity,ramp rate,response time,and response cost,a quantitative assessment model is developed for the aggregated interactive regulation capability of heterogeneous VPP resources and solved through a multi-objective optimization approach that combines the particle swarm optimization algorithm and the comprehensive membership degree method.Finally,simulation results demonstrate that the proposed method can accurately quantify the potential boundaries of VPPs in participating in ancillary services,providing a decision-making basis for operators to formulate optimal strategies and maximize their service value.关键词
