Modified Carbon Trading Based Low-carbon Economic Dispatch Strategy for Integrated Energy System with CCHP

Abstract

As the growing demand for environmental CO 2 emission reduction, low-carbon electricity has draw more attention. Integrated energy system (IES) is an important carrier for energy conservation and emission reduction. In the traditional low-carbon dispatch model for IES, carbon emission calculation is independent of the IES internal structure. Aiming for further control of carbon emissions according to carbon distribution in the energy conversion process, this paper establishes a modified low-carbon economic dispatch model for IES, which is based on carbon emission flow (CEF) for an energy hub and carbon trading. Before practical dispatch, analyze the carbon emission flow between different energy converters and bunches in the IES. Then carbon trading cost is considered in the optimal economic dispatch. The case study of models which applied to IES with combined cooling, heating and power units (CCHP), indicates that the proposed model controls carbon emission more stringent and is sensitive to carbon trading price.
