Optimization planning method of power distribution network comprising new energy power generation systems and special load

Abstract

The present invention discloses an optimization planning method of a power distribution network comprising new energy power generation systems and special load. Models are established for new energy power generation systems and a special load, and a photovoltaic charging station employs a direct current charging mode. A power distribution network comprising a single new energy power generation system or the special load is subjected to modeling analysis, and access points having the least influence on the electric energy quality of the power distribution network are taken as subsystem optimal arrangement points. A power distribution network comprising a plurality of new energy power generation systems or the special load is subjected to modeling analysis, and subsystems capable of offsetting electric energy quality influence are intensively arranged; each subsystem is ranked according to the influence on the electric energy quality, and each subsystem is arranged according to the arrangement rule of the power distribution network comprising the single new energy power generation system or the special load. The optimization planning method of a power distribution network comprising the new energy power generation systems and the special load have features such as initiative, integrity and the like on the electric energy quality of the power distribution network comprising the new energy power generation systems and the special load, and can be used for planning and management of the power distribution network comprising the new energy power generation systems and the special load.

Description

technical field [0001] The invention relates to a power grid optimization planning method, in particular to a distribution network optimization planning method including a new energy power generation system and a special load in consideration of power quality, belonging to the field of new energy distribution networks. Background technique [0002] With the scarcity of traditional energy and the increasingly prominent problems of energy conservation and environmental protection, new energy featuring energy conservation, environmental protection and renewable energy has gradually attracted worldwide attention. New energy includes solar energy, wind energy, ocean energy, biomass energy and nuclear energy. Among them, solar energy and wind energy have been greatly developed in recent years. Although new energy has many advantages, it is easily affected by natural factors and is random and intermittent. Most new energy power generation systems are connected to the grid through ...
