| Outline of Final Research Achievements |
Considering smart cities, we proposed network flow models with balancing supply and demand between plural energy sources, formulations of optimizations of the network flow problems, and their optimization methods. In these model, storage nodes describing buffer facilities and market nodes modelling markets where energies are trading are introduced newly.
Next the original fruit in case where convex assumption is not supposed with non-linearity characteristics in energy transformation, the new distributed optimization method is proposed, in which a total optimization problem is decomposed by the price coordination in market by using the augmented Lagrangian. Moreover, efectiveness of the new method to the above energy network flow models is cirtified.
