Abstract The uncertainty impacts of the distributed generations are considered to establish a configuration planning method for the distribution systems. Based on the fuzzy theory, the active and reactive power models of wind-driven generators and photovoltaic cells are formulated. Moreover, the minimum value of the annual average operating cost and the fuzzy expectation value are formulated as objective function, and the nodal voltage, network topology constraints and tidal current balance are formulated as constraints in the planning model. In accordance with fuzzy expectation value theory and boundary value-based distribution network, the fuzzy power flow calculation method is used to improve the integer coding method by genetic algorithm. Simulation examples show the feasibility and practicability of the proposed method.
