Low-Carbon Operation Strategy of Power System Considering Carbon Flow Demand Response

doi:10.11930/j.issn.1004-9649.202304043

Abstract

Abstract:

To address the problem that the traditional low-carbon dispatching methods for power system do not consider the carbon emission reduction potential of users, a low-carbon operation strategy of power system considering carbon flow demand response is proposed to adjust users' electricity consumption behavior and reduce the overall carbon emissions of power system. Firstly, based on the carbon emission flow theory and load-side carbon emission obligation allocation method, a user-side demand response method is established with carbon potential as signal. Secondly, the carbon emission cost is included in the economic cost of power system. Aiming at minimizing the total economic cost of the power system, a low-carbon optimal operation model of power system is established considering the carbon flow demand response. Finally, an IEEE 30 node system is simulated to verify the effectiveness of the proposed method.

Key words: low-carbon electricity, carbon emission flow, nodal carbon potential, demand response, optimal operation
