Regional power grid carbon emission management method suitable for new energy connection background

Abstract

The invention discloses a regional power grid carbon emission management method suitable for a new energy connection background. The method comprises the steps that S1, a regional carbon emission management model is established; S2, probabilistic flow based on a stochastic response surface method (SRSM) is adopted to calculate power grid flow distribution containing multiple associated new energy power stations; S3, an imperialistic competitive algorithm is adopted to solve the multi-target regional carbon emission management model to obtain a Pareto non-inferior solution set; S4, a penalty function is introduced to check and adjust obtained Pareto solutions, and node voltage limit exceeding or branch overloading is avoided; S5, an interactive satisfaction decision making method is utilized to select an ''optimal solution'' of the model from the Pareto solution set according to different demands of system operating personnel; and S6, comprehensive benefits of different schemes are evaluated by changing settings of new energy power station connection locations and all objective function reference memberships. Through the method, comprehensive management of practical power system carbon emission can be realized, and a new thought is provided for evaluation of address selection schemes of new energy stations.

Description

technical field [0001] The invention relates to the field of power system power generation planning, in particular to a carbon emission management method of a regional power grid applicable to the background of extensive access to new energy sources. Background technique [0002] In recent years, with the continuous growth of energy demand, environmental problems have become increasingly prominent. The promotion of energy conservation and emission reduction and the development of a low-carbon economy are effective measures to deal with the current climate warming and smog crisis, and are also the only way for sustainable development. At present, my country's power industry as a CO 2 Large emitters, accounting for more than 40% of the country's total carbon emissions. Therefore, at the power grid level, establishing an efficient and perfect carbon emission management mechanism and developing low-carbon power has great potential and has attracted widespread attention from th...
