Embodiment Construction

[0086] In order to better understand the present invention, the content of the present invention will be further described in conjunction with the accompanying drawings and embodiments, but the embodiments of the present invention are not limited thereto.

[0087] The present invention designs a multi-energy power system power planning method based on evolutionary game theory for large-scale multi-type power multi-point layout planning. The overall process of the algorithm is as follows figure 1 shown, including the following steps:

[0088] Step 1. Comprehensive power output characteristics, based on evolutionary game theory, regard power nodes as the main body of the game, and establish a power planning model;

[0089] Step 2. Calculate the timing characteristics and seasonal differences, select multiple typical days in a year, each typical day is divided into 24 time periods, and establish a multi-scenario model of node main body output timing;

[0090] Step 3. Select cont...

Abstract

The invention belongs to the field of power systems, and particularly relates to a power supply capacity configuration and layout planning method considering large-scale high-proportion new energy. Based on comprehensive analysis of technical and economic characteristics of a multi-energy power system consisting of wind power, photovoltaic power, photo-thermal power, hydropower, thermal power andenergy storage, a power supply planning model is provided based on an evolutionary game theory. The model takes each power supply node as a game main body, accumulates experience through time sequenceproduction simulation, continuously changes behavior rules of the power supply nodes, adjusts installed capacities of various types of power supplies to adapt to the environment, finally solves an optimal layout scheme of various power supply capacities of each node, and verifies that the proposed method has a remarkable effect on improvement of new energy consumption, so the efficient operationof a power system is ensured.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a power supply capacity allocation and layout method considering large-scale and high-proportion new energy. Background technique [0002] In recent years, with the increasing demand for energy and the increasingly urgent situation of environmental protection, renewable energy has received more and more attention, and the low carbonization of the power industry is the key to coping with global warming and realizing the sustainable development of my country's society and economy , a reasonable and effective power supply planning scheme will be a powerful means to ensure that the power system can achieve efficient carbon emission reduction under the premise of safe and stable operation, which also puts forward new requirements for power supply planning. A high proportion of renewable energy access will be one of the important directions for future grid development. [0003]...
