Problems solved by technology

At present, when formulating energy storage planning schemes for new energy power stations, most of them only take limiting grid-connected power fluctuations or other factors as a single optimization goal. Among them, some technologies have established multi-objective functions that consider multiple influencing factors. There is a constraint relationship between them, it is difficult to obtain the global optimal solution

Abstract

The invention relates to an energy storage planning method and device, and the method comprises the steps: building a multi-object planning object function of an energy storage system and constraint conditions of the multi-object planning object function; determining an optimal solution of the multi-object planning object function of the energy storage system; and carrying out the energy storage planning of a new energy power station according to the optimal solution. According to the technical scheme of the invention, the method achieves the planning scheme of the energy storage system in a mode of multi-target optimization, and guarantees the efficient and stable operation of a grid system.

Description

technical field [0001] The invention relates to the technical field of new energy storage control, in particular to an energy storage planning method and device. Background technique [0002] With the rapid development of society and economy, the shortage of fossil energy and environmental pollution are becoming more and more serious. Renewable energy such as photovoltaics and wind power has become a research hotspot for many scholars due to its clean and environmentally friendly advantages, and it has broad research and application prospects. Renewable energy will gradually become an important power energy resource in my country, and the transition from supplementary energy to alternative energy is about to be completed. [0003] However, renewable energy represented by wind power, photovoltaics, etc. has significant randomness, intermittent and volatility characteristics, which will bring great challenges to the stability, security and efficient operation of the power grid...
