Abstract: In this paper, To the theoretical basis for the bi-level programming, in accordance with customer needs at the regional location and on the electricity, heat and more dynamic demand for energy flow in order to build a regional energy systems and functions of the lowest total cost of the objective function, the establishment of a regional distributed energy systems network planning to build two-tier model, the distributed energy supply in the region the number, capacity, location, as well as supply points for each point on the demand for energy transmission network planning optimization.
