Carbon Emission Flow Calculation of Power Systems Considering Energy Storage Equipment

Clarifying the responsibility for carbon emissions is the fundamental task of establishing a low-carbon power system. Existing carbon emission estimation and analysis methods can yield the carbon emission distribution in the network. However, because energy storage devices have charging and discharging states, the established model is more complex and energy storage devices are usually ignored in the calculation of electric carbon emission flow in power networks. To handle this problem, this paper proposes an approach for calculating the carbon emission flows of power systems involving energy storage devices. A case using the IEEE 14-bus system is performed to present the calculation procedure and allocation of carbon emission flow in the power system.
