Optimal allocation of multi-objective self-provisioning power supply based on particle swarm optimization

Taking the independent microgrid with hybrid energy source of charging, light and diesel storage as the research object, the problem of optimal allocation of power supply is studied in depth. First, an optimization model containing three different optimization objectives, namely, economy, power supply reliability and renewable energy generation utilization, is established, and the number of self-supplied power sources, such as charging pile facilities, photovoltaic power generation systems, diesel generating sets and battery storage systems, is taken as a decision variable. Then, the optimization particle swarm algorithm is used to solve this optimization model. Finally, the effects of different types of self-provisioned power supply combinations on the results of power supply optimization allocation are analyzed by taking an independent microgrid on an island in Liaoning as an example.
