Cross-grid demand response (DR) coordinating framework in energy Internet-A case of power market participation of gas DR resources

Energy integration and energy internet enable cooperation of various energy network. Thus demand response (DR) can be extended from a pure power system issue to a cross-grid format. This paper initiates a coordinating market and operation framework for gas demand response to support power system supply-demand balancing. In the proposed framework, gas turbines help to transfer gas DR into power generation. The gas aggregators collect the flexible gas resources and make offers to power grid. The cross-grid demand response model of gas flexible loads is established to obtain the equivalent 'Cost-Generation-Capacity' for power market competition. The awarded generation capacity of gas DR aggregators will also be optimally distributed to all gas DR suppliers. A numerical study is implemented to demonstrate the feasibility of the proposed framework and model.

Automated summary

This paper introduces a coordinating market and operation framework for gas demand response to support power system supply-demand balancing. Gas turbines are used to transfer gas DR into power generation, while gas aggregators collect flexible gas resources and make offers to the power grid. The proposed framework establishes a cross-grid demand response model for gas flexible loads to optimize generation capacity distribution and demonstrate feasibility through numerical studies.
