Abstract

The invention discloses an optimized dispatching method for a power distribution network containing distributed power supplies. The method comprises the following steps: collecting data, market information and uncertain information of all nodes of the distributed power supplies in the power distribution network in different regions, carrying out the preprocessing on the data, market information and uncertain information, and storing the data, market information and uncertain information into a data information cloud platform; calling the data information cloud platform, and based on the multi-target attribute of the system and by taking the economic benefit of the power distribution network, the loss of the power distribution network and the power generation cost of the distributed power supplies as optimization targets, constructing an optimized dispatching model for the power distribution network according to constraint conditions; taking the constraint conditions as decision analysis conditions, outputting prediction data of each region and a given specific range of uncertain fluctuation, inputting corresponding operation schemes and uncertainties into a plurality of optimization objective functions, and calculating overall benefits; and allowing decision makers of different regions to compare the overall benefits of schemes and the development conditions of the regions to select an optimal strategy as an optimized dispatching scheme.

Description

technical field [0001] The invention belongs to the technical field of distribution network operation optimization, in particular to a distribution network optimization scheduling method and system including distributed power sources. Background technique [0002] As an emerging technology, under the guidance of energy-saving and emission-reduction policies, most distributed power sources use energy-saving and environmentally friendly new energy sources. Distributed power generation mainly uses the following new energy sources to generate electricity: wind energy, solar energy, biomass energy, ocean energy, natural gas and other forms of new energy. Distribution network optimization technology integrating distributed power generation and energy storage units can effectively improve energy utilization efficiency and reduce environmental pollution. [0003] However, the output power of wind power generation, solar photovoltaic power generation, etc. has great randomness, and ...
