Investigation on Regional DES Energy Supply Network Planning Based on Bi-Level Programming

Based on the theory of Bi-level Programming, according to the location and the fluctuant power and heat demand of the customers in the given region, taking the minimum cost of the regional energy supply as objective function, a bi-level programming model was formulated to plan the regional distributed energy supply chain network. A hybrid algorithm of a tabu search algorithm combined with k-means algorithm and a simulated annealing algorithm combined with scanning algorithm has been provided to solve the model. Finally with practical instances we proved the validity of the approach.
