Smart micro-grid system

Abstract

The invention relates to a smart micro-grid system. The smart micro-grid system comprises a local control layer, a network communication layer, a master station layer and a software layer, wherein the local control layer is in communication with the master station layer through the network communication layer, and the master station layer is in communication with the software layer through an information interaction bus. The smart micro-grid system integrates photovoltaic power generation, wind power generation, multiple types of energy storage systems multiple in capacity and modern power electronic, communication and control technologies. While high-reliability power supply is achieved, optimized allocation of renewable energy resources and high-reliability power supply to loads in a micro-grid are achieved; the interaction relation between the micro-grid and an external power grid is reflected correctly, and the effect of distributed energy on improvement of power supply reliability is fully shown; operation data of photovoltaic, wind power and energy storage systems and the micro-grid systems can be collected and stored, and the operation data are accumulated for researches on key technologies about micro-grids. The smart micro-grid system solves the problems that an existing micro-grid system is low in energy utilization ratio and poor in environmental benefit, electric energy quality and power supply reliability.

Description

technical field [0001] The invention relates to the technical fields of electric power and power grid, in particular to an intelligent micro-grid system. Background technique [0002] Today, with the rapid development of the times, the demand for electricity is growing rapidly, and the load is increasing. The power sector mostly focuses on the construction of thermal power, hydropower, nuclear power and other large-scale and Chinese power sources and ultra-high-voltage long-distance transmission networks. However, with the scale of the power grid With the continuous expansion of the world, the disadvantages of ultra-large-scale power systems are becoming more and more prominent, such as high cost, difficult operation, and difficulty in adapting to users' increasingly high safety and reliability requirements and diversified power supply needs. A new round of energy transformation characterized by clean energy and smart grid is advancing globally, with the direction of energy ...
