An Optimal Dispatch of Microgrid Based on Improved Particle Swarm Algorithm

The complex multi-constraint and multi-objective nonlinear optimization problem of optimal dispatching of microgrid is paid much attention by the studies. This study suggests the optimized dispatching of the micropower grid based on the improved particle swarm optimization algorithm (IPSO) for full playing to the power generation advantage of distributed energy. A multi-objective microgrid model under photovoltaic power generation prediction and load prediction is modeled mathematically for the objective function for optimization. The battery’s service life and the lowest economic cost are considered multi-objective criteria for solving the optimization problem by the IPSO algorithm. The experimental results’ validity confirmed that the proposed scheme works well with the micropower grid through case analysis.
