Several variations to the composition and operation strategy of a metropolitan region’s centralized energy park are analyzed in this work. These variations are defined in an attempt to increase the system’s share of renewable energy (RE) in electricity and district heating consumption, as well as the share of power from Combined Heat and Power (CHP) plants in electricity consumption. A decrease in the system’s total annual CO2 emissions and total annual costs is also pursued. In particular, two RE integration options are analyzed: Power to Heat (PtH) units, and Power to Gas to Combined Heat and Power (PtGtCHP) plants.

In this work, several variations of the centralized energy supply of a metropolitan region are modeled, simulated and analyzed. The aim of these variations is, on the one hand, to increase the share of renewable energy (RE) in the electricity and district heating supply and, on the other hand, to increase the share of electricity from combined heat and power plants in the electricity supply. A reduction of the annual CO2 emissions as well as of the annual total costs of the system is also pursued. In particular, two options for the integration of RE are analyzed: “Power to Heat” units (PtH) and “Power to Gas to Combined Heat and Power” plants (PtGtCHP).
