Research on Analysis Method of Influence Degree of Distribution Network Operation Efficiency

This article takes actual load-duration-curve as research object, that describes a distribution network device in one year working hours' efficiency, and analyzes the degree of power distribution capacity during the device evaluation period. When we need to evaluate and analyze the operation efficiency of the distribution network in a certain area, we need to analyze it according to the operation efficiency evaluation model, and then we will further analyze the weak links, such as which sub-items will affect the overall impact on the operational metrics, and finally we will be able to know these weaknesses that need to be solved first. This paper proposes a three-level analysis method for the influence degree of distribution network operation efficiency. The index model of the influence degree of single equipment, similar equipment at the same level, and system operation efficiency are built. The practicability and effectiveness of this method is verified through examples. The proposed method can make up for the shortcomings of the distribution network operation efficiency evaluation model in the analysis of weakness. The method can help to find the key factors affecting the distribution network operation efficiency more accurately, and the direction and measure of the distribution network optimization are further proposed.
