Optical storage charging station day-ahead charging and discharging strategy optimization method

The invention relates to a day-ahead charging and discharging strategy optimization method for an optical storage charging station, and belongs to the technical field of energy storage charging and discharging strategies. The method comprises the following steps: constructing a light storage charging station mathematical model, an energy storage life loss model and a charging station internal electric energy scheduling model; determining constraint conditions, wherein the constraint conditions comprise a power constraint for purchasing electricity from a power grid, a photovoltaic capacity constraint, a maximum power change value constraint, an equivalent loss constraint and an energy storage system general constraint; and finally, based on constraint conditions, solving the model to obtain an optimal strategy. The optimal strategy obtained by the invention can effectively reduce the economic cost and the carbon dioxide emission in most extreme scenes, and the effectiveness and the universality of the method
