A new methodological approach of sizing and operation optimization for cogeneration by internal combustion engines

The goal of this article is to present a robust and relatively simple to apply mathematical model to determine the optimal size and operation of the main equipment of cogeneration plant with internal combustion engines. The concerned installations are the gas engines and the peak boilers. The presented model optimizes the power of the equipment to be installed, as well as their instantaneous loads. Contrary to previous studies on rated parameters, this analysis takes into account continuous load variation in the range of 50% to 100% for the engines and 0% to 100% for the boilers.
