Abstract

The invention relates to a micro-grid system and a micro-grid system-based fuzzy control method. The micro-grid system comprises a fuzzy control system, distributed energy power supply equipment and an electrical appliance, wherein the fuzzy control system is used for acquiring electrovalence information of the conventional grid and the power information of the distributed energy power supply equipment; and the electrical appliance is managed by adopting the fuzzy control system. By adopting the fuzzy control method in the micro-grid system, optimal compromise between the power consumption satisfaction of a user and reduction in a load peak is realized, power consumption peak is avoided, the burden of the micro-grid system is lowered, power consumption expense is saved, and the contradiction between power consumption supply and demand is further relieved.

Description

【Technical field】 [0001] The invention relates to a microgrid system and a fuzzy control method based on the microgrid system. 【Background technique】 [0002] At present, with the increasing shortage of energy in the world, the rapid development of enterprises and the increase of residential electrical appliances, there is a great contradiction between supply and demand in the traditional power grid. In the process of using electric energy, the period of intensive consumption of electric energy forms the peak of electric load, and the period of little electric energy consumption forms the valley of electric load. Generally speaking, the unit capacity utilization rate used to ensure the peak power load only accounts for about 1-2% of the total operating hours of the unit in a year, which leads to an increase in investment in power supply equipment, but a decrease in utilization rate, which makes the cost of power supply continue to increase . According to statistics, reside...
