With the vigorously development of microgrid, the benefit of power grid company will be affected when cooperating with microgrid. Choosing the microgrid with distributed photovoltaic generation and energy storage as the research object, taking the maximum annual income of the power grid company and the minimum annual cost of the investment management of the microgrid as target, the planning of microgrid is accomplished under different cooperative development modes of power grid company and microgrid and the revenue of power grid company under the optimal planning scheme is compared. The least square method is used to simplify the double objective function and the genetic algorithm is used to solve it. Finally, taking the microgrid adapted from an actual power grid in east China as an example, the simulation calculation is carried out, and the harmonious development mode of power grid company and microgrid development is obtained. Thus the availability of distributed photovoltaic generation and energy storage in the same location for investment management of microgrid and power grid company earnings is verified.
