| With the development of low-carbon electricity,carbon emission obligation allocation has become a concerned research topic.In order to conquer the challenge of how to allocate carbon emission obligation in demand side in load-based cap-and-trade mechanism,this paper apply carbon mission flow theory and nodal marginal analysis theory to deal with it.Also this problem is analyzed from the perspective of cooperative game theory.The four demand side carbon emission obligation allocation methods based on footprint carbon intensity,marginal carbon intensity,Shapley value and prenucleolus are demonstrated,respectively.Their theory basis(like power flow tracing,locational marginal pricing and cooperative game theory)and computation methods are also analyzed.With considering the characteristics of this problem,a fundamental criteria evaluation system is established and illustrated,including efficiency,symmetry,etc.Based on the fundamental criteria system,the four allocation methods are compared and analyzed comprehensively.Comparatively,the Shapley value based allocation method can better measure the interactions among loads and reflect the loads’ locations and capacities.It is concluded that the Shapley value based method can calculate the actual contribution of each load to carbon emission of the whole system and then determine the corresponding carbon emission obligation of each load.The conclusion is verified by the simulation results.The other three methods are discussed and their flaws are analyzed.However,due to the high computational complexity,the Shapley value based method is suitable to certain situation.In order to balance fairness and computational efficiency,an appropriate combination of the Shapley value and nodal carbon intensity is a possible way in future research. |
