Abstract

The invention discloses an analysis method for power distribution network power supply capacity. The method comprises the following steps: acquiring physical data and electricity market data of a power distribution network system net rack architecture in the power distribution network to respectively establish a first sensitivity matrix and a second sensitivity matrix corresponding to each other;and analyzing the power supply capacity of the power distribution network by utilizing the first sensitivity matrix and the second sensitivity matrix. Compared with a way of only analyzing the power supply capacity of the power distribution network by only considering the power distribution network system net rack thickening, load increasing and like physical layer factors, the physical data of the power distribution network system net rack architecture is combined, and the market data of the electricity market is combined when analyzing the power supply capacity of the power distribution network, thereby improving the accuracy of analyzing the power supply capacity of the power distribution network. Furthermore, the invention further discloses an analysis device for the power distributionnetwork power supply capacity, and a storage medium with above effects.

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to an analysis method, device and storage medium for power supply capacity of distribution network. Background technique [0002] The power supply capacity of the distribution network is an important index to evaluate the distribution network. At present, the research on the power supply capacity of the distribution network is carried out on the basis of the power supply capacity of the transmission network. [0003] Before the reform of the power sales side, the power supply capacity of the distribution network was mainly affected by physical factors such as the grid structure of the distribution network system and the load growth mode. The grid structure of the distribution network system is based on the grid power supply, mainly based on the capacity of the substation, the number of substations, transformer taps, reactive power compensation equipment, and the wiring ...
