Combined heat and power plants towards efficient and flexible operation

The integration of large-scale renewable energy sources into the power system and the implementation of market mechanisms have changed the operation of combined heat and power (CHP) plants. Technical and organizational measures should be taken to operate power plants efficiently and flexibly in line with new running conditions. There are different kinds of possibilities to ensure flexible operation of CHP plants. In line with the review and analysis of the provided literature all measures were generalized and divided in five groups. At the end, an example of the research topic is presented in the context of Riga CHP-2 plant.
