Combined Heat and Power Economic Dispatch Using Modified Shuffled Frog Leaping Algorithm

In this paper a new method has been proposed to solve Combined Heat and Power Economic Dispatch (CHPED) based on Modified Shuffled Frog Leaping Algorithm (MSFLA). Difficulty on complexity of the problem is related to its constraints. This algorithm can satisfy constraints simply. This optimization algorithm has a wide spread search space and this characteristic helps to achieve optimum solutions. Application of MSFLA in CHPED problem has been simulated on two test cases. Numerical results show that MSFLA has proposed better solutions in comparison with other existing methods.
