According to the method, the operation of a micro-grid is safer and more reliable, the energy estimation of an energy storage device is more accurate, the parallel operation of the power grid, the energy storage device and a power generation device in the micro-grid is more coordinated and stable, a simple frame structure is applied to the arithmetic method, the matching of software and hardware is more practical, and the method can be better implemented in various platforms. By adopting the intelligent micro-grid energy storage control method, large-scale access of a distributed power supply and renewable energy sources is fully embodied, high-reliability supply of various energy forms to a load is realized, intelligent control of a small power operation management system on power utilization is realized, free utilization of renewable energy sources and efficient utilization of conventional energy sources are combined to form a self-control, protection and management autonomous system.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to an intelligent micro-grid coordination control strategy method. Background technique [0002] Today, microgrid technology is an autonomous system capable of self-control, protection and management, and because of its low cost, low voltage and low pollution, it is gaining increasing popularity in areas with complex power grid environments and poor power quality. promote. [0003] Generally, a microgrid refers to a network composed of multiple distributed power sources (with small capacity) and their related loads (energy storage devices, energy conversion devices, related loads and monitoring, protection devices, etc.) according to a certain topology. The switch is connected to the normal grid. As a complete power system, microgrid relies on its own control and management to realize power balance control, system operation optimization, fault detection and protection, power q...

Problems solved by technology

However, the traditional battery energy storage technology and algorithm are relatively single, and there are large errors in the calculation of the battery state of charge, resulting in a lack of strong guarantee for the stability of the microgrid, and the poor coordination between the energy storage device and the microgrid.
