Control and simulation of power balance in optical storage micro-grid based on photovoltaic power supply
Micro-grid is one of the most effective ways to utilize renewable energy. It is of great significance to study how to realize the energy management of micro-grid and optimize the utilization of energy. Micro-grid is a system unit composed of distributed power generation, energy storage device, energy conversion device, load, control and protection device, etc. It is an autonomous system that can realize self-control, protection and management. Most of the power sources in the micro-grid are distributed power sources, such as wind turbine, photovoltaic power generation, micro gas turbine, fuel cell, super-capacitor, flywheel battery and other energy storage devices. Connecting them to the user end has the characteristics of low cost, low voltage and low pollution, and is the mainstream development direction of the current power system. This paper introduces the composition and control technology of micro-grid, as well as the energy management and simulation of optical storage micro-grid in island and grid-connected mode. In this paper, two modes of island and grid connection are simulated by Simulink. The results show that the optical storage micro-grid system with switching mechanism can effectively improve the utilization rate of photovoltaic power, realize the efficient integration and utilization of distributed power supply, and carry out load side operation management autonomously by switching switch.
