Abstract
This paper proposes on-line optimal operation planning and control of cogeneration systems (CGS). CGS is usually connected to various facilities such as refrigerators, reservoirs, and cooling towers. In order to generate optimal operation planning for CGS, startup/shutdown status and/or input/output values of the facilities for each control interval should be determined. The facilities may have nonlinear input-output characteristics. Therefore, the problem can be formulated as a mixed-integer nonlinear optimization problem (MINLP). Particle Swarm Optimization (PSO) can be easily expanded to be utilized for MINLP. The proposed PSO-based methods are applied to typical cogeneration planning problems with promising results.
