The invention relates to a distributed energy storage optimization configuration method. The method comprises the following steps: calling an optimal configuration model; solving the optimal configuration model in combination with a preset economic objective function and a preset constraint condition to obtain an optimal solution of the energy storage capacity and the power parameter; and performing energy storage optimization configuration by using the optimal solution, wherein the preset economic target function takes the maximum net present value NPV, the minimum dynamic payback period Pt and the maximum internal return rate IRR as targets. The method considers comprehensive benefits of investors, users and a power grid, the maximum net present value NPV, the minimum dynamic payback period Pt and the maximum internal return rate IRR are taken as targets, the optimal solutions of the energy storage capacity and the power parameters are solved in cooperation with corresponding constraint conditions for control, the potential of energy storage configuration in distributed photovoltaic power generation is fully excavated, and the economical efficiency of energy storage configuration is improved.
Description
technical field [0001] The invention relates to the technical field of new energy storage configuration, in particular to a distributed energy storage optimization configuration method. Background technique [0002] In recent years, new energy photovoltaic power generation projects have shown a "blowout" growth trend. Due to the geographical distribution of solar energy resources, these photovoltaic power generation projects are mainly concentrated in the "Three North" regions with weak grid structures and low load levels. The surplus of new energy power. In addition, since the output of photovoltaic power generation cannot always be kept constant and is seriously affected by the weather, in cloudy or rainy weather, the output of photovoltaic power will fluctuate drastically. At the same time, with the construction and investment of hundreds of kilowatts or even megawatts of photovoltaic power stations, the randomness of their power will bring serious harm to the operation...
