Abstract: The proposal and development of the Energy Internet makes it possible to convert different energy network. Therefore, by expanding the demand response of the power system to the gas network, a coordinated market and operation framework for power demand response resources is established to support the demand of gas networks cross grid. In the proposed framework, the gas turbine is used as the coupling point of the electricity-gas dual grid, and the grid demand response resources are used to replace part of the output of the coupling point gas unit, so that the gas turbine saves part of the amount of natural gas, which is equivalent to converting power into gas. A cost model for cross-grid support of power demand response resources has been established to obtain the “Cost-Equivalent Gas Volume” of these resources to participate in the gas market competition. At the same time, the bid-winning equivalent gas volume of this demand response resources in the gas market will also be allocated to the resource owners participating in the process in accordance with the principle of lowest cost. Finally, the feasibility of the proposed model and framework is verified through numerical analysis. The framework provides good suggestions for power grid demand response resources to support natural gas network operation.

Key words: energy internet, power system, demand response, cross-grid, gas market
