Research on Reconfiguration Strategy of Distribution Network Based on Improved Group Search Optimization Algorithm

The uncertainty of photovoltaic output makes it more difficult to achieve optimal control of power distribution system reconfiguration and reliable grid restoration. This paper uses fuzzy theory to improve the traditional group search optimization algorithm and expand it to the two-dimensional search space. Therefore, an optimization strategy of self-healing reconfiguration control for distribution network fault recovery based on improved GSO algorithm is proposed. Through the simulation analysis of the IEEE33-node system, the economy and reliability of this strategy in the distribution network containing photovoltaic power generation are verified. The results show that the distribution network fault reconstruction strategy based on the improved GSO algorithm can reduce the active power loss of the system after the fault is restored, and at the same time improve the efficiency of the reconstruction optimization path solution.
