In this paper a new approach for the solution of the Combined Heat and Power Economic Dispatch problem (CHPED) is being presented using Biogeography-Based Optimization (BBO). Biogeography-Based Optimization (BBO) is a type of evolutionary algorithm which is based on the theory of biogeography and is inspired from the two concepts-migration of species between “islands” via flotsam, wind, flying, swimming, etc. and mutation. The proposed test system takes into account seven units and also a comparison with Artificial Bee Colony Algorithm (ABC) is being made. From the results it is seen that BBO provides best solution than ABC.
