The invention provides a game theory-based photovoltaics, energy storage and power transmission network coordinated planning method. The method comprises the steps of analyzing a balance and restriction relation between photovoltaics, energy storage and a power network in a system; analyzing a game relation among the photovoltaics, the energy storage and the power network in a market environment,and game feasibility; building a network source coordinated planning model after light storage access based on a non-cooperative game theory; providing a dispatching simulation strategy with a goal ofminimizing the coal consumption cost of a thermal power unit and the minimum auxiliary service cost of an energy storage system; and obtaining an optimal light storage network configuration scheme. For the problem that the current light discarding phenomenon is prominent, the coordinated planning of a photovoltaic power station, an energy storage device and a network frame is realized from multiple angles such as a power supply structure, a power network structure, a power network operation mode and the like, and the photovoltaic consumption rate is effectively improved on the basis that theload demand and the reliability are met.
