Research on Virtual Inertia of AC/DC Hybrid Microgrids Based on the Firework Algorithm

This paper presents an improved firework algorithm to efficiently conFigure the virtual inertia for AC/DC hybrid microgrids with distributed energy and high penetration, which can solve the problem of efficient utilization of virtual inertia resources in hybrid microgrid. Firstly, the virtual inertia configuration evaluation model of hybrid microgrids is derived and established. Additionally, to reduce the difficulty of inertia optimization configuration, this paper converts the inertia configuration optimization problem from non-convex to convex optimization. Thirdly, this paper mainly optimizes the particle selection method of the firework algorithm, and introduces the vector optimization domain to directionally select the particles in the optimal domain. Finally, compared with the traditional firework algorithm, the simulation results of the improved firework algorithm has stronger ability to find optimized areas and more accurate performances.
