#### Abstract

In this paper there is presented a review of the cogeneration systems based on Stirling engines. There are also presented assumptions of climate and energy policy of the European Union in 2030. It is also explained, how distributed generation works and what are the types of distributed generation depending on sources size. There are also listed devices of distributed generation with their range of power. Then, it is explained the concept of microcogeneration understood as the combined production of electricity or heat by small and medium power devices. In the further part of this paper, it is presented a review of the Stirling engines. The basic formulas for theoretical efficiency of the Stirling engine and its theoretical work were derived. It is also shown the basic types of Stirling engines (alpha, beta, gamma) and the exemplary method for its use in µCHP (micro combined heat and power - microcogeneration). This piece of work was written to conduct positional research of the alpha type Stirling engine. Research was carried out to check possibilities of using the Stirling engine in microcogeneration systems and to check the methods of steering its work parameters. The alpha type Stirling engine and computer with LabVIEW software were used during the research. The research was made in three stages, with three different pressure values of the working gases (nitrogen and argon): 3 bars, 5 bars and 6 bars. During each stage there were measured temperatures: on the heater, on the regenerator on the side of the heater, on the regenerator on the side of the cooler, on the cooler and rotation speed, pressure in the work space and current electric of the system load. After carrying out research, the results were analyzed in MATLAB software and presented as charts: power in function of the rotation speed, pressure in function of the time and indicator diagrams. According to the charts, with the increase of pressure in the working space increases the power of the engine (the maximum power points vary linearly) and is increased the maximum rotation speed of the engine. It is also suggested the method of determining the indicator diagrams in order to implement them into simulation model.
