The volatility of renewable energy in active distribution networks poses challenges to energy storage and regulation.Existing technologies such as battery systems are effective for small fluctuations,but insufficient for large-scale regulation.A method for automatic layered coordination and interactive control of source-grid-load-storage in active distribution networks is proposed.The characteristics of photovoltaic,wind power,load,and energy storage is analyzed to construct characteristic models,and these characteristic models are used as important foundations and constraints for constructing scheduling objective function models.an objective function model suitable for coordinated management and control of active distribution networks is constructed.The use of harmonic search algorithm is introduced to solve the optimal solution,achieve hierarchical control and coordinated management.The experimental results show that the proposed method shows significant effectiveness in the analysis of active distribution network characteristics.Compared with other methods,it can more effectively reduce the error between output allocation and frequency control results,further reducing losses.
