Abstract:two-stage approach to solve the resulting complex and numerically difficult Non-convex Mixed-integer Nonlinea R Feasibility Problem

1.Introduction:

Today, gas trading takes Place at virtual, liberalized, and non-discriminatory, with consumers, suppliers, storage, and transportation handled by different independent players.

TSO Has to ensure the delivery of the traded gas from suppliers to consumers.

NoVA is an important problem during the TSO.
