Abstract

The invention provides a microgrid energy storage optimization scheduling method based on a sparrow search algorithm, and the method comprises the steps: 1, carrying out the analysis of all distributed power supplies and storage battery energy storage equipment in a microgrid, collecting a renewable energy power generation power prediction curve, a load prediction curve and a gradient electricity price of each distributed power supply and storage battery energy storage equipment in the microgrid; and step 2, with the lowest cost under the dynamic gradient electricity price as a target, establishing a micro-grid optimization operation target function, determining operation constraint conditions of the micro-grid optimization operation target function, and establishing a micro-grid optimization scheduling model according to the micro-grid optimization operation target function and the operation constraint conditions. According to the method, the total cost of electricity price is reduced by performing optimal scheduling on the energy storage system of the micro-grid, the limitation of the maximum charge and discharge depth of the storage battery is considered, the sparrow search algorithm is combined, stable and safe operation of the micro-grid is realized, and the influence of renewable energy power generation intermittency and volatility in the micro-grid is reduced.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to a microgrid energy storage optimization scheduling method based on a sparrow search algorithm. Background technique [0002] Due to the advantages of environmental protection, huge energy content, flexible power generation and sustainable utilization, distributed renewable energy has received extensive attention and rapid development in recent years. Distributed energy is usually affected by the environment, so it has strong volatility and intermittency, which affects the safe and stable operation of the power system. Moreover, complex and diverse distributed power generation technologies are not conducive to the full utilization of energy, resulting in waste of resources. In order to coordinate the contradiction between distributed power generation and the large power grid, a microgrid (Microgrid), which can realize the flexible connection of distributed power g...
