Event-driven low-carbon economic dispatch for multi-regional power grid considering power consumption behavior

Abstract

The trend of low-carbon power puts forward new standards and challenges for the operation of power system, and also makes the optimal dispatching of power system more difficult. In order to better realize the low-carbon economic operation of the power system, this paper proposes a bi-level low-carbon economic dispatching (LCED) model for multi-regional power system. In the upper level, a carbon emission constraint based on event-driven mechanism tailored for coordinated operation of multiple regions is proposed, and the optimal objective is to minimize the total operating cost of the system. In the lower level, the reduction of carbon emission obligation on the load side is considered, and the optimal objective is to maximize the low-carbon utility on the load side. Thus, the synergy of the low-carbon goal on both source and load sides is achieved. Finally, through the simulation of the modified IEEE 39-bus system, it is verified that the proposed bi-level model can effectively reduce operating costs and reduce carbon emissions, and improve the level of renewable energy consumption.
