Description

technical field [0001] The invention relates to the technical field of distributed independent power generation capacity configuration, in particular to a multi-objective wind-solar diesel storage capacity optimal configuration method based on an improved immune particle swarm algorithm. Background technique [0002] Among clean energy sources, wind energy and solar energy have great development value due to their abundant resources and low pollution. At present, wind energy and solar energy technologies are gradually mature, and the utilization rate is greatly improved. However, in the process of power supply, considering the discontinuity, randomness and high volatility of wind energy and solar energy, and taking advantage of the complementary advantages between wind energy and solar energy, a distributed system of wind energy and diesel storage is proposed. Wind energy and solar energy are not fixed. The power source will change with the season and climate. The energy sto...
