The optimal configuration process of the AC-DC hybrid power system will be affected by the output uncertainty of photovoltaics and wind turbines, and the power system planning effect is poor. Therefore, a medium- and long-term double-layer optimal configuration planning method for the AC-DC hybrid power system is designed. We will introduce the binary variable model into the uncertainty model, calculate the influence parameters of wind and light resources on the optimal configuration of the AC-DC hybrid microgrid, calculate the power flow of the AC-DC power system, set the objective function and system power conditions, perform capacity optimization, and realize AC-DC power flow. The experimental results show that the proposed planning method improves the estimation accuracy of the voltage phase angle interval and the voltage amplitude, and also reduces the commutation loss and planning cost, and meets the actual design requirements.
