摘要

The Combined Heat and Power Plants (CHP) are characterized by the combined production of electricity and heat and by saving 37% more of the primary energy compared to the conventional power plant. High unit efficiency, a low investment cost, reduction of transmission losses and the support system for producers of electricity and heat in the high-efficiency cogeneration process - result in the use of CHP installations for various recipients, including a small professional heat and power plants, hospitals, educational facilities, sports centers, office buildings, hotels, housing estates, airports, sewage treatment plants, greenhouses, dryers and industrial factories. Due to the variable thermal energy demand and technical limitations of the used devices, such as the minimum and maximum electrical and thermal power of the unit - the selection of the optimal gas engine is a multi-criteria task. One of the criteria, most often determining the algorithm of selection, is the economic effect. The paper presents selected methods of multi-criteria decision making used for the purpose of the gas cogeneration engine selection, taking into account the minimum emission of harmful substances and the maximum possible return in the assumed period of operation.
