Smart central strategy control system for micro-grid

Abstract

The invention discloses a smart central strategy control system for a micro-grid. The smart central strategy control system for the micro-grid comprises a micro-grid electrical system. The micro-grid electrical system comprises a distributed electricity generation unit, an energy storage unit, an environment monitoring unit, a simulation load unit, an actual load unit, a communication network unit and a central strategy control unit. The smart central strategy control system for the micro-grid further comprises an information collection system unit and a central control processing unit. According to the smart central strategy control system for the micro-grid, overall control, coordination and optimization of electricity generation equipment, electricity consumption equipment and electricity consumption quality of the micro-grid can be achieved, the intermittent energy electricity generation plan, the load electricity consumption plan, load control, energy storage, the diesel engine electricity generation plan and the like are involved, and the functions of emergency electricity consumption control, automatic grid-connected / grid-disconnected switching control, adverse current prevention control, black-start control, peak load shifting, time shifting and the like of the system can be achieved. In communication, the smart communication detection technology and the channel hot standby redundancy technology are adopted additionally, and the stability and the reliability of communication are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation, and relates to an intelligent central strategy control system for a microgrid. Background technique [0002] With the continuous development of the national economy and the rapid growth of electricity demand, the disadvantages of the traditional power grid model, such as high cost and difficult operation and maintenance, have become increasingly prominent. In order to better adapt to users' increasing safety and reliability requirements for electricity consumption, as well as diversified power supply needs, distributed power generation models have received more and more attention in recent years. [0003] Microgrid mainly refers to a (small) distribution sub-network composed of distributed power generation devices, energy storage links and local loads, while distributed power generation is more inclined to use new renewable energy sources (wind and solar energy, etc.).
