From: Realistic modeling of a combined heat and power plant in the context of mixed integer linear programming

  No. Decision variables Description Type
Generation 1 \( {P}_t^{available} \) Actual available electrical output power of the CHP [kW] C
2 \( {P}_t^{set, elec} \) Set value for the electrical output power of the CHP [kW] C
3 \( {P}_t^{thermal} \) Thermal output power of the CHP [kW] C
4 \( {\delta}_t^{on} \) If CHP is in operating mode \( {\delta}_t^{on} \)= 1, else 0 B
5 \( {\delta}_t^{start- up} \) Start-up process in t: \( {\delta}_t^{start- up} \)= 1, else 0 B
Consumption 6 \( {P}_t^{fuel} \) Fuel consumption of the CHP [kW] C
Thermal storage 7 E t State of charge [kWh] C
8 \( {Q}_t^{charge} \) Charging power [kW] C
9 \( {\dot{Q}}_t^{discharge} \) Discharging power [kW] C
