Embodiment Construction

[0063] The method for optimal access location and capacity planning of distributed power sources considering multi-agents in the present invention will be described in detail below in combination with embodiments and drawings.

[0064] Such as figure 1 As shown, the optimal access location and capacity planning method of the distributed power supply considering multi-agents in the present invention includes the following steps:

[0065] 1) Establish a distributed power model, that is, a prediction model for the output of the distributed power photovoltaic power generation system;

[0066] The described distributed power supply model is:

[0067] P=nI×A×η 0 [1-γ(T p -T γ )] (1)

[0068] In the formula, n is the number of solar panel components, I is the radiation intensity on the inclined surface of the photovoltaic panel, A is the area of ​​a single solar panel, and η 0 is the module efficiency at the reference temperature, γ is the temperature coefficient of the photovo...

Abstract

The invention discloses a distributed power supply optimal connection position and capacity planning method taking multiple subjects into consideration. The method includes the steps: building a distributed power supply model, namely, a prediction model of photovoltaic power generation system output; building an outer layer optimization model taking a power distribution network as a subject; building an inner layer optimization model taking a user as a subject; building a distributed power supply optimal access location and capacity solution algorithm based on a genetic algorithm. According tothe method, a distributed power supply model can be accurately built, many-sided benefits are comprehensively considered, and distributed power supply optimal access capacity and location is determined by two-layer optimization and multi-subject game. An important basis can be provided for optimal access of a distributed power supply in a power distribution network, an important foundation servesas optimal planning of an active distribution network, the power distribution network is planned based on the important foundation, adverse effect of a distributed power supply on the power distribution network can be decreased, efficient, economical and excellent running of the power distribution network is facilitated, the planning level of an urban distribution network can be improved, and reasonable development of an urban active distribution network is facilitated.

Description

technical field [0001] The invention relates to a distributed power supply optimal access location and capacity planning method. In particular, it relates to a distributed power supply optimal access location and capacity planning method that considers multi-agents and is suitable for distributed power supply access work in distribution network planning. Background technique [0002] With the development of society and economy, the demand for electricity is increasing day by day, and the energy problem is becoming more and more serious. The power supply mode characterized by "large power grid, large power plant, and high voltage" has exposed its own disadvantages. In order to improve this situation and alleviate the energy crisis and environmental pollution problems, power grids in many regions have begun to introduce measures to encourage the access of user-side distributed power to the distribution network, and the access of distributed power to the distribution network ha...
