ON SOME COMPUTATIONAL PROBLEMS RELATED TO THE EFOM-12C MODEL
We review three questions related to the numerical treatment of the EFOM-12C model. A first problem is the reconstruction of the dual variables of the EFOM-12C after its reduction and optimization. Because of its size, the EFOM 12C model is normally reduced prior to its optimization. The software RECREATOR allows one to reconstruct the optimal primal variables of the original problem but does not consider the question of the dual variables. The report discusses how these can be obtained. The two other parts of the report summarize other works conducted in the context of the same project and reported in separate papers. A numerical study of the efficiency of the codes LIFT and DECOMPSX has been conducted on various multiregional multiperiod energy flow models of the EFOM-12C type, various recommendations are made in this context. Finally a new nested decomposition algorithm that simultaneously exploits the multiregional and multiperiodic structure of the constraint matrix has been developed.
