Intelligent lighting load power adjusting and control method

Abstract

The invention provides an intelligent lighting load power adjusting and control method. The invention provides a mode which carries out grouping and in-group priority management on the accessed lighting loads; each group participates in unified priority distribution of a micro-grid system; a master control system gives an adjusting and control target for each group according to overall requirement, and each group is adjusted and controlled according to the preset strategy and in-group priority; and meanwhile, multi-way dynamic adjustment of configuration parameters is realized, and the method is used conveniently and quickly. The method can adjust the lighting loads automatically and quickly according to the change of power limit values, thereby ensuring priority operation of some important groups and important loads within the group; and for some lighting loads having specific needs, the original operating state thereof can be maintained through locking. Through the adjusting and control method, intelligent and automatic management of all lighting loads can be realized, thereby greatly improving stability and intelligence of the micro-grid system, saving energy consumption, and realizing economic benefit.

Description

technical field [0001] The invention relates to the technical field of micro-grid control in smart grids, in particular to a method for intelligently regulating lighting load power. Background technique [0002] Microgrid is a new type of network structure, which is a system unit composed of a group of micro power sources, loads, energy storage systems and control devices. It is also an autonomous system capable of self-control, protection and management. It can be operated in parallel with the external grid or isolated. In the microgrid, lighting is often the main load with a relatively large proportion. Self-control and management of lighting load can effectively improve the automation and intelligence of the microgrid autonomous system. [0003] The existing smart grid management of the lighting system is usually based on the application of lighting loads in some scenarios, and lacks constraints on the power of lighting loads in the system. Under grid-connected condition...

[0003] The existing smart grid management of the lighting system is usually based on the application of lighting loads in some scenarios, and lacks constraints on the power of lighting loads in the system. Under grid-connected conditions, external grid power is limited or power supply power under isolated grid conditions In the case of insufficient power, the lighting load cannot be automatically adjusted according to the needs to meet the power limit. It needs to be remotely controlled through the background system or manually adjusted on site. However, the number of loads connected to the system is large, and it is time-consuming and laborious to operate according to the existing method. The need for rapid response to the microgrid
