Design of Two-stage Trading Mechanism for Active Distribution Network Integrating Photovoltaic and Storage Clusters
摘要
Abstract
A trading mechanism design for the integration of photovoltaic(PV)and storage clusters in active distribution network is proposed,aiming to facilitate the large-scale development of distributed PV and centralized grid-connection scenarios.The design,based on the K-means algorithm,comprehensively takes into account factors such as spatial distribution concentration and multi-machine output similarity.Additionally,hierarchical cluster analysis of distributed PV combined with non-parametric ideas is conducted to aggregate distributed PV resources.Based on the results of the distributed PV clustering analysis,the configuration of the PV-storage clusters is carried out.By analysing the interaction between the power grid and distributed PV users,a distribution network trading mechanism between lower-level users and the upper-level grid is designed based on a two-stage electricity pricing model.Through the simulation analysis of numerical examples,the enhanced K-means algorithm is employed for hierarchical clustering analysis of distributed PV,which is then applied to configure PV-storage clusters.Leveraging the outcomes of this clustering analysis,a trading mechanism based on a two-stage electricity pricing model is developed to investigate the hierarchical clustering analysis methodology and the operational models of aggregators in the context of large-scale distributed PV development.The proposed approach is validated to maximize aggregator revenues,reduce user-side distributed PV opportunity costs and payments,ensure users'active engagement in ancillary peak regulation services,and effectively enhance the overall efficiency and stability of the system.关键词
