An Effective Heuristic for Combined Heat and Power Production Planning with Power Ramp Constraints

Aiying Rong, Risto Lahdelma, An Effective Heuristic for Combined Heat and Power Production Planning with Power Ramp Constraints. Applied Energy 84(3), 307–325, 2007.

Abstract:

Combined heat and power (CHP) production is an increasingly important power production technology for efficient utilization of primary energy resources and for reducing CO2 emissions. In the CHP plant, generation of heat and power follows a joint characteristic, which makes the determination of both the marginal power production cost (MPPC) and the feasible operating region for the plant more complicated than for the power-only generation plant. Due to the interdependence between heat and power production, the power ramp constraints, which limit how much the power production of a CHP plant may increase or decrease between two successive periods, may also imply constraints on the heat production. In this paper, we investigate the impact of power ramp constraints on CHP production planning and develop a robust heuristic for dealing with the power ramp constraints based on the solution to the problem with relaxed ramp constraints (RRC). Numerical results based on realistic production models show that the heuristic can generate high-quality solutions efficiently.
