The modeling of gas network contingencies into the SCUC is not a trivial task because it results in a nonlinear, non-convex, and large-scale problem difficult to solve.
A detailed gas network model was formulated, and considerations of gas storage and line pack were introduced in [10, 11].
A M-GEOPF model incorporating PtG units is formulated based on precise nonlinear power and gas flow models, where the dynamical characteristics of the gas network are specifically modeled.
Based on the above discussion, the primary contributions of the present work are as follows: 1) A M-GEOPF model incorporating PtG units is formulated based on precise nonlinear power and gas flow models, where the dynamical characteristics of the gas network are specifically modeled.
In this section, a power flow model for coordinated electricity and gas network is presented.
The column-and-constraint generation (C&CG) is adopted to solve the proposed integrated robust model, in which nonlinear natural gas network constraints are reformulated via a set of linear constraints.
A comprehensive and optimal mathematic model of a gas networks system is established in this paper which considers all the factors influencing the total investment of a gas networks system (e.g. pipe diameter, thickness, pressure, length, compression ratio, etc).
