Bi-level Programming of AC/DC Hybrid Distribution Network Based on Improved Genetic Algorithm

DC distribution network can enhance the transmission capacity of lines and enhance the flexibility of network topology. However, the increase in the feasible solution of the network topology poses a challenge to the optimization solution. From the perspective of the optimization model, the traditional planning model usually adopts bi-level programming method, which is difficult to be solved. The enhancement of topology flexibility increases the complexity and nonlinearity of the problem. In this paper, based on the characteristics of the bi-level programming model of AC/DC hybrid distribution network, an algorithm based on improved genetic algorithm is proposed. The comparison shows that the proposed algorithm is effective to solve the bi-level programming model and the convergence is fast. The AC/DC hybrid distribution network scheme has more advantages than other ones.
