To improve the economy and stability of microgrid operation, it is necessary to optimize the capacity of microgrid reasonably according to the meteorological information and load information. Under this background, a mathematical model of distributed power sources is established. According to the constraint conditions and operation strategy for the system, the number of distributed power sources is taken as an optimization variable, and the minimum total cost is taken as an objective function. The improved immune particle swarm optimization algorithm is used to optimize the capacity of microgrid. First, normal distribution is used for initialization, so as to increase the population diversity. Then, the nonlinear inertia factor, adaptive inertia weight and chaotic disturbance operator are used to improve the convergence speed and accuracy of the algorithm. Experimental results show that the proposed method is reasonable and can effectively reduce the investment cost, providing a reference value for the capacity optimization of microgrid.
