Optimization of energy storage in the active distribution network with multiple microgrids

A multi-objective optimization method for energy storage optimization in active distribution networks with multiple microgrid is proposed to address the low utilization of renewable energy in active distribution networks and the optimal scheduling of distributed energy storage. Firstly, on the basis of the microgrid model, a multi-objective optimization model with minimizing microgrid costs and distribution network losses is approved, taking into account the distribution network power flow constraints, microgrid internal power balance constraints, energy storage power and loss constraints. The optimal energy storage charging and discharging power can be obtained. And the optimal scheduling of the active distribution system is realized using the optimization model. Finally, the effectiveness of the proposed method is verified by simulations.
