Abstract

To enhance the economy and reliability of independent microgrids and obtain the optimal ratio of each configuration in the microgrid, research on the optimal capacity configuration of microgrids based on the improved Harris Hawks optimization algorithm is conducted. Taking the average annual comprehensive cost as the objective function, and comprehensively considering various constraints and the demand response theory of time-of-use electricity prices, the configuration model and operation strategy of the wind-solar-diesel-storage microgrid are constructed. Aiming at the problems that the Harris Hawks optimization algorithm is prone to local convergence and insufficient accuracy when solving models, an improved Harris Hawks optimization algorithm integrating ICMIC chaotic mapping, sine cosine algorithm, crisscross algorithm and Levy flight strategy is proposed. Through non-zero solution test function, the improved Harris Hawks optimization algorithm was tested and compared with the Harris Hawks optimization algorithm, the gray wolf optimization algorithm and the ant-lion optimization algorithm, verifying that the improved Harris Hawks optimization algorithm has better convergence performance. Finally, meteorological data and load data of a certain area were selected for case analysis. It was found that the annual comprehensive cost was reduced by 10.71%, 17.37% and 7.92% respectively compared with the other three algorithms, verifying the effectiveness of the improved Harris Hawks optimization algorithm.
