HIERARCHICAL COORDINATION OPTIMIZATION METHOD OF REGIONAL MICRO-ENERGY-GRID GROUP BASED ON SCENARIO CONSTRUCTION TECHNOLOGY
Considering the uncertainty of wind stroke,light output,and load power in regional micro energy networks,a hierarchical coordination optimization method for new energy consumption in regional micro energy networks is proposed.Introduce a normal Copula function to establish joint distribution relationships between time and conditional correlations of various random variables,thereby establishing typical scenarios of uncertainty.After considering the losses and prediction error costs of wind and light abandonment,a hierarchical coordinated optimization model is established with the goal of minimizing the operating cost of the micro energy network.The upper layer of this model is the coordination and consumption optimization of flexible resources in the micro energy network group,while the lower layer is the internal consumption optimization of the micro energy network.Using a hierarchical optimization method based on objective cascading analysis to iteratively solve,a hierarchical coordination optimization strategy for regional micro energy networks is obtained.Finally,an example of a micro energy grid group was used for validation,indicating that the proposed method improves the new energy consumption rate of the regional power grid.
