Low-carbon Operation Method of Integrated Energy System in Ecological Park Considering Carbon Footprint

Reducing carbon emission is vital for the ecological park construction. A low-carbon operation strategy of integrated energy system (IES) in eco-parks is proposed in this paper. The accurate quantification of carbon emissions of different power generation equipment is executed in the way of carbon footprint. The participation of IES in the carbon trading market is considered, and a stepped carbon trading mechanism is used to guide the IES in eco-parks to control its carbon emissions. The combined heat and power (CHP) unit with adjustable thermoelectric ratio is introduced to improve the operation economy of the ecological park. A low-carbon operation model is established, with the operation target of minimizing the operation cost, including the carbon emission cost, electricity and gas purchase cost and cost of abandoning wind power and photovoltaic. The results of numerical examples demonstrate the effectiveness of the proposed model.
