Multi-period integrated natural gas and electric power system probabilistic optimal power flow incorporating power-to-gas units

Natural Gas and Electricity Optimal Power Flow

In this paper, the combined natural gas and electric optimal power flow (GEOPF) is presented. It shows fundamental modeling of the natural gas network to be used for the GEOPF, and describes the equality constraints which describe the energy transformation between gas and electric networks at combined nodes (i.e., generators). We also present the formulation of the natural gas loadflow problem,...

Integrated Natural Gas, Heat, and Power Dispatch Considering Wind Power and Power-to-Gas

A large amount of wind power has to be curtailed due to the inflexibility of the combined heat and power (CHP) system in the heating season in northern China. The power-to-gas (P2G) technology, which uses electricity to produce hydrogen or synthetic natural gas, has become a promising energy conversion option for the utilization of surplus power energy. In this paper, an integrated natural gas,...

Decomposed Electricity and Natural Gas Optimal Power Flow

Different energy infrastructures, such as electricity, natural gas and local district heating systems utilized for the energy supply are most often planned and operated independently of each other. This paper addresses the optimization of combined electricity and natural gas networks. The couplings between the two energy infrastructures are taken into account with the novel concept of energy hu...

Stochastic Optimal Operation and Risk Analysis for Integrated Power and Gas Systems

The increment integration of renewable distributed energies means the desired operation of the electric power system will significantly depend on the performance of primary energy. In this order, an integrated approach for mutual interaction between the electricity and natural gas systems has been considered for the purpose of ensuring optimal energy exchanging between the electric power system...
