Abstract

The invention discloses a power distribution network operation efficiency optimization method. The method comprises the following steps: obtaining a cost function of consumption cost of each subunit of each SECC system at a preset moment, and establishing an objective function of each SECC system according to the cost function; and obtaining constraint conditions of each subunit of each SECC system, and establishing an optimization model of each SECC system according to the constraint conditions and the objective functions. The optimization model of each SECC system is established only, so that the technical problems that the stability and the efficiency of the distribution network serving as a power transmission terminal in the prior art greatly affect the satisfaction degree of users, but the research on influence factors of SECC combined distribution network operation is too little are solved.

Description

technical field [0001] The present application relates to the technical field of SECC distribution network, in particular to a method for optimizing operation efficiency of a distribution network. Background technique [0002] With the global energy shortage, the proportion of photovoltaic and other new energy sources in the distribution network energy supply is gradually increasing. In the optimal operation of the distribution network, the substation-energy center system formed in cooperation with the energy center plays a significant role in improving the operation efficiency and absorbing new energy. At the same time, due to the community distribution of users, it is of great significance to study the joint operation of multiple SECCs (substation-energy center systems) for the operation efficiency and stability of the distribution network. As the terminal of power transmission, the distribution network has a great impact on user satisfaction due to its stability and effi...
