Mobile microgrid system

Abstract

The invention discloses a mobile microgrid system including an AC high voltage part, an AC low voltage part and a DC part. The AC high voltage part includes a high voltage interface, a transformer high-voltage switch and a transformer. The AC low voltage part includes a transformer low voltage switch, an AC bus, a plug-and-play AC interface-side low voltage AC switch, different-type distributed resource plug-and-play AC interfaces and an AC / DC module. The DC part includes an AC / DC module DC-side DC switch, a DC bus, a plug-and-play DC interface-side DC switch, an intra-system energy storage system and different-type distributed resource plug-and-play DC interfaces. According to the invention, the microgrid system is constructed when a main grid gets damaged, so that local area power supply is realized and small area power balance and energy optimization are achieved. At the same time, high electric power customized demands of users for absorption of distributive resource, uninterrupted power supply and reactive and electric power mass compensation and the like are met.

Description

technical field [0001] The invention relates to a mobile micro-grid system, which belongs to the technical field of vehicle power supply equipment. Background technique [0002] At present, power system equipment maintenance and emergency repairs are mostly carried out in the state of power outage. If the operation cannot be carried out in time due to bad weather or other reasons, it will inevitably lead to a long-term power outage, which will cause huge economic losses and negative social impact. Especially in the face of irresistible natural disasters such as ice and snow, floods, thunderstorms and other disasters, the original operation methods and measures cannot fundamentally solve the outstanding contradictions such as the normal supply of power energy urgently needed for disaster relief in a timely and effective manner. [0003] The existing vehicle-mounted mobile substation can meet the basic needs of power transformation and power distribution under natural disaster...

Problems solved by technology

[0005] Purpose: In order to solve the problem that the vehicle-mounted mobile substation, as a substation link in the power system, cannot be used alone and cannot restore regional power supply when the main grid is damaged, the invention provides a mobile micro-grid system to solve how to install the main grid The problem of building a micro power system under the condition of being damaged can realize local area power supply, as well as small area power balance and energy optimization; at the same time, it can meet the high power formulation needs of users, such as the consumption of distributed resources, uninterruptible power supply, reactive power and power quality compensation
