In Hysopt there are two CHP models:
Combined Heat & Power
This model contains the yield curves of a combustion engine CHP, depending on the incoming return temperature, thermal and electrical power is generated. Same as the heat flow controlled boiler, the user must apply a control loop on this model. The input on this model is a power modulation signal between 0 and 1.

Boiler with Stirling engine
Like the previous model, this model also includes yield curves but from a Stirling engine. Depending on the incoming return temperature, thermal and electrical power is generated. Most of the time is it used in combination with a normal boiler.

Both models are also displayed in the Hysopt Inspiration library under the folder "Hybrid production".
