Recently, combined heat and power units, known as
cogeneration, which produce both heat and electrical power, have played an
increasing in different industries. In order to utilize CHP units more
efficiently, economic dispatch problem is applied to determine the optimal
combination of the power and heat outputs of system while satisfying heat and
power demand and other constraints with minimum fuel cost. This problem is
known as combined heat and power economic dispatch (CHPED). Due to complex
characteristics, heuristic and evolutionary based optimization approaches have
became effective tools to solve the CHPED problem. The problem which is used in
this paper is non-linear, non-smooth and non-convex. Harmony Search Algorithm
is applied to two tests with different characteristics. The obtained results
demonstrate the efficiency of the proposed method in solving non-convex and non
smooth problems, with considering and non considering the transmission loss and
also with both equal and different initialization of the problem for the same
CHP units.
