Resilience-Oriented Optimal Planning of Gas-Fired DGs in Electrical Distribution Networks Considering Damage of Natural Gas Network

Abstract

Natural hazards such as earthquakes are of the main causes of destruction in important infrastructures such as electricity and natural gas networks. Planning of distributed generations is a compelling method for increasing the resilience of energy infrastructures against such events. This paper presents a resilience-oriented planning framework for gas-fired distributed generations (GFDGs) in distribution networks, considering the outages of electric-gas network components, dispatching the electric repair crews, and proper utilization of installed GFDGs. The proposed framework is formulated as a mixed-integer linear programming (MILP) optimization problem. The results of applying this MILP model on the IEEE 33-bus distribution system supplied by the 14-bus natural gas network show that considering operational actions such as dispatching repair crews or possible damages to network components can have a significant impact on achieving more optimal expansion plans.
