10.1 Introduction

Combined Heat and Power (CHP) production has been introduced as a much more efficient scheme to generate power in plants and heat in boilers, offering higher energy efficiency and far lower fuel consumption [1]. Following the increasing growth of CHP units over the last decade, the conventional Economic Load Dispatch (ELD), which determined operating points of thermal plants in power‐only production optimization problems, is transformed to Combined Heat and Power Scheduling (CHPS). Obviously, considering a primary objective function that is minimizing the operational cost, more constraints involved in the CHPS make it more difficult to solve compared to the ELD. As the most severe constraint to be satisfied, load balance including both power and heat can be pointed out. The authors ...
