Gridding coordinated planning method of composite energy multi-energy complementation

Abstract

The invention provides a gridding coordinated planning method of composite energy multi-energy complementation. The method comprises following steps of acquiring current situations of the power grid and energy resource utilization condition information; initial dividing grids in a demonstration area, predicting load and composite energy demands, and correcting a grid division scheme of a geographical information system; formulating constraints and net rack planning rules, constructing a composite energy coordinated development basic model, and formulating a target net rack coordinated planningscheme; formulating a target net rack scheme of each level year and each long-range year, and carrying out composite energy coordinated planning operation management service platform construction; and carrying out economical benefit estimation and providing a demonstration region power distribution network composite energy coordinated development operation mode. According to the invention, the park can be quite properly and rationally planned; a composite energy planning optimal scheme can be obtained; by use of the gridding method of the geographical information system, coordinated planningis carried out, and energy interaction and gradient utilization are achieved; the peak adjusting pressure of the power grid is reduced; and the digestion ability for clean energy is improved.

Description

technical field [0001] The present invention relates to the field of comprehensive park planning, and more specifically, to a grid-based coordinated planning method for a comprehensive energy multi-energy complementary system. Background technique [0002] With the increasing level of industrial production and residential consumption, the traditional energy supply mainly based on coal and oil is facing severe problems such as resource depletion and environmental pollution. Rational development and utilization of clean energy such as natural gas, photovoltaics, and wind energy, and comprehensive utilization of energy such as cogeneration of heat, power, and cooling to improve energy utilization efficiency and clean energy consumption capacity have become the future development trend of urban distribution networks. [0003] So far, the traditional planning methods have not fully considered the energy conversion between electric energy and storage equipment. Some existing plann...

Problems solved by technology

[0003] So far, the traditional planning methods have not fully considered the energy conversion between electric energy and storage equipment. Some existing planning methods only consider the direct one-way conversion mode of electric energy and natural gas, but do not pay more attention to electricity, gas, heat, and renewable energy. Can complement the deep coupling relationship for analysis
