At the same time, in the analysis of electrical systems in the existing technology, most only stay at the simple schematic of equipment connection, failing to deeply analyze the interaction of electrical parameters and the influence of control signal conduction. When equipment operates in combination, it is impossible to comprehensively and in real time grasp the dynamic operation data of the system and equipment, unable to accurately generate the combined independent characteristics representing the combined collaborative energy efficiency of equipment, and it is difficult to achieve high-efficiency cooperation between equipment. In addition, in terms of the output of energy efficiency management and control schemes in the existing technology, it is usually roughly adjusted based on experience or a single index, without comprehensively considering various requirements such as energy efficiency improvement, equipment operation stability, and cost-effectiveness.
