Problems solved by technology

[0006] However, there is an inherent contradiction between the randomness of power users and the stability of power supply, which constantly tests the load capacity of microgrids and power grids
It is precisely because of this that correspondingly, the problems of control and stability of electric energy are caused.

Embodiment Construction

[0031] The technical solutions of the present invention described above will be further understood by those of ordinary skill in the art through the description of specific embodiments in conjunction with the accompanying drawings.

[0032] According to the present invention, the essence of the energy storage control method for realizing the intelligent microgrid is that the microgrid gathers the control information of each module through the communication network, and performs data recording, data analysis, and coordinated control with the central monitoring unit as the core. In addition to the central monitoring unit, each circuit has its own processor, which can perform initial calculation and memory.

[0033] In order to realize this intelligent control method, figure 1 The block diagram of the figure shows a corresponding hardware topology for implementing the intelligent microgrid energy storage control method of the present invention. Such as figure 1 As shown, the ha...

Abstract

The invention discloses an intelligent micro-grid energy storage control method. The intelligent micro-grid energy storage control method is an algorithm integrating micro-grid coordination control, energy storage management and energy balance. The control method coordinates internal control with energy balance of a micro-grid, energy storage, micro-grid and power grid energy models are built, and independent energy control is integrated into a system for stable and effective operation. Compared with a traditional micro-grid control method, micro-grid operation is safer and more reliable, energy estimation of an energy storage device is more accurate, parallel running of the power grid, the energy storage device and power generation devices inside the micro-grid is more coordinated and more stable, the arithmetic method applies the simple frame structure, software and hardware matching is more practical, and the method can be better implemented in various platforms.

Description

technical field [0001] The invention relates to electric energy control technology, in particular to an intelligent microgrid energy storage control 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 quality m...
