ABSTRACT:
The Combined Heat and Power Economic Dispatch (CHPED) problem is a highly nonlinear and non-convex optimization challenge that requires the simultaneous scheduling of thermal, combined heat and power (CHP), and heat-only units to meet specific power and thermal demands while accounting for complexities like valve-point loading and emission constraints. To overcome the limitations of conventional methods in handling these discontinuous search spaces, this paper proposes the application of the Mantis Search Algorithm (MSA), a bio-inspired metaheuristic technique that effectively balances global exploration and local exploitation through an adaptive hunting strategy. Validated on standard 7-unit benchmark systems, simulation results demonstrate that the MSA outperforms existing algorithms such as the Aquila Optimizer, African Vultures Optimization, and Coot Optimizer by achieving superior economic performance, including minimum operating costs of 9995.3284 $/h and 10080.39$/h for different load cases.
