Inter-provincial power purchase plan arrangement method taking regard of energy saving and emission reduction

Abstract

The invention provides an inter-provincial power purchase plan arrangement method taking regard of energy saving and emission reduction. The method comprises steps that I, a multi-target power purchase model comprehensively taking regard of the least total power purchase cost, the least total energy consumption of a thermal power set, the least SO2 emissions and the least CO2 emissions is established; II, single-target power purchase models respectively taking regard of the least total power purchase cost, the least total energy consumption of the thermal power set, the least SO2 emissions andthe least CO2 emissions are established and solved; III, dimensionless processing is carried out based on the four indexes; IV, a weighted value of each index is determined according to actual conditions; and V, the index values after dimensionless processing and the respective weighted value are utilized to establish a target function, a multi-target optimization problem is converted into a single-target optimization problem, the particle swarm optimization algorithm is further utilized for solution, and an inter-provincial power purchase plan taking regard of energy saving and emission reduction is made. The method is advantaged in that for the made inter-provincial power purchase plan, energy consumption of the thermal power set and pollution gas emission are reduced on the condition that the power purchase cost can be reduced.

Description

technical field [0001] The invention relates to the field of power purchase plan formulation by grid companies, in particular to a method for arranging cross-provincial power purchase plans considering energy saving and emission reduction. Background technique [0002] In recent years, with the continuous deepening of power reform and the successive promulgation of related supporting documents, more and more attention has been paid to the issue of cross-regional and cross-provincial power market transactions. In this context, the goal of each provincial power grid company should be to formulate a reasonable power purchase plan based on user-side demand, and arrange cross-regional and cross-provincial power purchases. Considering that the total energy consumption of thermal power units under different power purchase plans, the safety of system operation, and the degree of pollution to the environment are not the same, so how to comprehensively consider various factors and for...
