Low-carbon demand response strategy of power system based on event-driven mechanism

Achieving the goal of carbon neutrality necessitates the urgent transition of the power system towards decarbonization. Most existing low-carbon optimization methods for power systems primarily consider direct decarbonization from the power source side. However, it is the demand of power consumers that is the fundamental cause of carbon emissions on the power generation side. Therefore, adopting low-carbon power consumption strategies on the demand side is also one of the key measures to reduce carbon emissions. This paper proposes a low-carbon demand response (DR) strategy based on time-of-use (TOU) electricity prices and event-driven mechanisms. The strategy uses actual carbon emissions as the trigger for events and adjusts TOU electricity prices through event-driven mechanisms to guide consumers in price responsiveness, which achieves the integration of price incentive signals and carbon signals. A case study is conducted on the IEEE 39-bus system to analyze and validate the effectiveness of the proposed method in improving load characteristics and reducing carbon emissions.
