Distributed power supply planning method considering output fuzzy randomness

Abstract

The invention discloses a distributed power supply planning method considering output fuzzy randomness. The method comprises the following steps: 1) performing data import and initial value input; 2)proposing a typical daily scene generation method considering distributed power supply output fuzzy randomness; 3) based on the typical daily scene generation method, proposing an active power distribution network double-layer distributed power supply planning method; and 4) in combination with a specific power distribution network structure, respectively taking the maximum annual income of the distributed power supply supplier and the minimum annual network loss cost of the power distribution company as optimization objectives, and carrying out optimization configuration on the position and capacity of the distributed power supply. Through the distributed power supply planning method considering fuzzy randomness, reasonable configuration and grid structure optimization of the distributedpower supply can be carried out, win-win of multi-benefit subjects is realized, and consumption of the distributed power supply is promoted.

Description

technical field [0001] The invention relates to the field of distribution network planning, in particular to a distributed power supply planning method considering the fuzzy randomness of output. Background technique [0002] Distributed power generation planning refers to determining the installation location and configuration capacity of distributed power generation on the basis of known load forecast results and distribution network operating conditions, so as to optimize the economy and reliability of the distribution network during the entire planning period. . [0003] Today, a single power supply system characterized by large units, large power grids, and high voltage can no longer meet the increasing requirements for power quality, safety and reliability. It has increasingly become a research hotspot at home and abroad. However, the rapid development of distributed power has also brought a series of problems to the power system, such as the unreasonable installatio...

Problems solved by technology

However, the rapid development of distributed power has also brought a series of problems to the power system, such as the unreasonable installation location will reduce the reliability of the system; the large access capacity will cause "abandoning light and wind", overvoltage and other phenomena, If it is too small, it will not be able to fully play its positive role in improving voltage quality and reducing network loss.
