With the increase in the investment in the gas-fired electricity generation technology, capturing the operation constraints of the natural gas network in the electricity and natural gas operation problems becomes more crucial. The nonconvexity in the feasibility region formed by natural gas network constraints will impede achieving the global solution for these problems. This letter proposed an algorithm to procure a tight and tractable convex relaxation for the natural gas network constraints that can be leveraged in the electricity and/or natural gas network operation problems. The merit of the proposed algorithm is illustrated using a case study and the efficiency of the proposed formulation is compared with mixed integer linear and semidefinite programming formulations.
