Feasible Domain Analysis of Resource Aggregation for Building Groups Flexibility Based on Improved Enumeration Method

The feasible domain analysis of flexibility resources in building groups is of great significance for regulating the overall operational stability of distribution networks. The feasible domain analysis is based on the flexibility resource aggregation model, the process of which needs to consider various factors such as network constraints, temporal coupling characteristics and spatial coupling characteristics of flexibility resources. In this paper, an equivalent method is used to construct a building group aggregation model considering the above elements to achieve the elimination of temporal and spatial coupling of flexibility resources within the building group. The actual feasible domain after dimensionality reduction is obtained by the highdimensional polyhedral projection method, and then the range of the feasible domain is determined by the step-by-step enumeration of vertices method, and finally the validity of the method is proved by experimental verification.
