Resilient operation planning of integrated electrical and natural gas systems in the presence of natural gas storages

摘要

In this paper, a new model is proposed for emergency response of Power Grid Systems (PGS) to severe events in the presence of Natural Gas (NG) storages. The PGS?s transmission lines outages as well as NG pipelines outages are integrated in this model. The optimal Network Reserve Requirement (NRR) allocation and NG storage scheduling are studied as emergency response strategies to relief sever events repercussion in PGS. The proposed method is linearized using the combination of piecewise linearization approach and big-M method. The effectiveness of the proposed MILP model to improve system resilience are verified through four case-studies on modified 24-bus IEEE test system integrated to 20-node NG network.
