Resumen:
One of the main factors impacting the system reliability nowadays is the growing interdependence between electricity and gas networks due to the increase in the installation of gas units. Security-constrained unit commitment (SCUC) models are utilized to economically schedule generating units without compromising the system reliability. This paper proposes a novel SCUC formulation that includes dynamic gas constraints, such as the line pack. A Benders’ decomposition with mixed-integer programming techniques is developed to solve the problem efficiently. The master problem calculates the unit commitment guaranteeing gas transmission feasibility. Hourly subproblems minimize network violations of the power system for pre- and post-contingency conditions. Including dynamic gas networks into the SCUC allows accounting for the flexibility and reliability that power systems demand from gas systems in the short term. The IEEE 118-bus system is integrated with the Belgian high-calorific gas network for validating the formulation.
Palabras clave: Benders’ decomposition, mixed integer linear programming, natural gas, security-constrained unit commitment.
