Power planning method and device for power distribution network, equipment and computer readable storage medium

Abstract

The invention provides a power planning method and device for a power distribution network, equipment and a computer readable storage medium. The power planning method comprises the steps that (1) the abundance and peak load regulation margin of a main transformer, a generator set and a power load outside a system are determined; (2) a probability corresponding to the abundance is predicted, and an abundance probability table is formed according to the abundance and the corresponding probability; (3) power balance calculation is performed according to the abundance probability table to obtain values of main transformer capacity, installed capacity and new energy set capacity needing to be increased outside the system; (4) power balance calculation is performed according to the abundance probability table to obtain off-grid capacity of the main transformer and capacity which should be generated by the generator set outside the system; (5) prediction is performed according to historical data to obtain a probability corresponding to the peak load regulation margin, a peak load regulation margin probability table is formed according to the peak load regulation margin and the corresponding probability, and the electric quantities of wind curtailment and light curtailment are obtained through calculation; and (6) a power load curve is corrected, so that the electric quantities of the wind curtailment and the light curtailment are smaller than a predetermined value.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a power planning method, device, equipment and computer-readable storage medium for a distribution network containing a high proportion of distributed new energy. Background technique [0002] Distributed new energy refers to small wind power and photovoltaic power sources scattered at or near the user site. Distributed new energy with nearby power generation and decentralized power supply can effectively reduce user electricity bills, reduce power supply network losses, improve power supply quality and reliability, increase the proportion of clean energy use, improve the overall efficiency of energy resource use in the whole society, and reduce pollutant emissions. It brings huge economic and social benefits, and has very important positive significance for building a safe, stable, clean and environmentally friendly energy supply system. [0003] However, a high proportion of d...

Problems solved by technology

In order not to affect the safe operation and power supply quality of the distribution network, artificial restrictions have to be placed on the access capacity and methods of distributed new energy, which greatly restricts the development and consumption of distributed new energy.
