Embodiment Construction

[0140] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0141] An environment-economic dispatching method for an electricity-gas interconnection system in a coastal area according to this embodiment. In this implementation mode, firstly, an air pollutant diffusion model is established that takes into account the local sea-land circulation and the thermal inner boundary layer; then, combined with the air pollution diffusion model in the coastal area, a multi-objective environmental economic scheduling model of the electric-gas interconnection system is established; finally, the ADMM-based The multi-objective distributed optimization algorithm is used to solve the electricity-gas distributed collaborative optimization. Such as figure 1 As shown, the method includes the following steps:

[0142] Step A1, establishing an atmospheric pollutant diffusion model that takes i...

Abstract

The invention discloses an environmental economy scheduling method for a coastal region electricity-gas interconnection system, and the environmental economy scheduling method comprises the followingsteps: 1), building an atmospheric pollutant diffusion model considering local sea-land circulation and a thermal inner boundary layer for the characteristics that the meteorological conditions of thecoastal region are complex and changeable and the atmosphere has regional features; 2) in combination with an atmospheric pollution diffusion model, establishing a multi-objective environmental economic dispatching model of the electricity-gas interconnection system by taking economic cost, carbon emission and pollutant concentration contribution values as optimization objectives; 3) adopting anADMM-based multi-objective distributed optimization algorithm to carry out electricity-gas dispersion collaborative optimization solution, and 4) inputting a scheduling scheme obtained by solution into a power grid scheduling system to obtain a power scheduling plan of the regional power grid.

Description

technical field [0001] The invention relates to the field of environmental economic scheduling of electric power systems, and proposes an environmental economic scheduling method for electricity-gas interconnection systems in coastal areas. Background technique [0002] In recent years, with the continuous increase of China's industrial and commercial scale, the level of power load has continued to increase, and the environmental pollution caused by power system power generation has gradually attracted attention. Power system contributes 31% of China's SO 2 emissions and 30% NO x emission. The environmental pollution control problems caused by the power industry have been extensively studied by experts at home and abroad, including: desulfurization and denitrification of pollutants [2-3] , improve the utilization rate of clean energy and study the environmental benefits of clean energy power generation, and consider the environmental economic dispatch of environmental pro...
