Description
Summary:The low matching degree of photovoltaic output and load in the pv-storage microgrid will reduce the reliability of its power supply. Therefore, it is necessary to configure a certain capacity energy storage device to support source-load balance.This article first analyzes the impact of different load configurations and application scenarios on energy storage configuration, and then proposes an energy storage capacity configuration scheme with the minimum operating cost of the microgrid as the objective function and the constraints of the minimum power fluctuation in the network, and uses an improved particle swarm algorithm solve the solution. Finally, a numerical example is used to verify that the solution can stably support the source-load balance in the microgrid, reduce the power exchange at the common connection point of the microgrid, and improve the microgrid's own power supply capacity.
