Abstrakt: In order to improve the working state of flexible multi-state switch and optimize the control technology of power grid, an optimization model of multi-objective function is established and multiswarm particle swarm optimization (MPSO) algorithm is used. The results show that the improved MPSO algorithm can avoid the local optimal solution and find the global optimal solution, which improves the convergence accuracy of the whole power grid system. Moreover, after adding three port flexible multi-state switch to optimize, the value of minimum node 18 node of voltage distribution changes from 0.913 before optimization to 0.974, which is 0.061 optimized compared with before. The value of network loss changes from 202.67kW before optimization to 114.81kW after optimization, which reduces about 88kW. The results show that with the addition of three port flexible multi-state switch, the situation of voltage overrun is optimized, and the network loss in the system is also significantly improved. This shows that the voltage level of the whole distribution network can be improved effectively after the flexible multi-state switch is optimized, and its economic applicability is improved, and the security of the whole power grid system is ensured.
