Abstract

Combined heat and power (CHP) plants are a well-known technology for industrial and district heating appliances. As those plants are often used to optimally satisfy thermal demands they are often run heat-controlled. The power generation profiles of those plants are badly predictable. Those badly predictable power generation profiles are fluctuating and central power plants have to work in the times when the heat-controlled plants do not run. Due to these circumstances it should be analysed to what extent a power-controlled operation can be applied. For this purpose a dynamic simulation of the whole system is necessary. This paper will present the possibilities of a dynamic simulation of a one-family-house with a power-controlled micro-CHP unit and a thermal storage.
