Optimal microgrid placement for enhancing power system resilience in response to weather events

Extreme weather events can potentially cause multiple component outages in power systems and result in electricity supply interruptions. The installation of microgrids in proper places in power systems can be considered as a viable solution to this problem which is under investigation by many electric utilities in the Unites States. Considering this issue and the growing number and intensity of extreme events, this paper develops a microgrid optimal placement model that determines the optimal size and location of microgrids in power systems that can maximize system resilience. The model is developed considering multiple component outages and limited investment budget. The problem is formulated using mixed-integer linear programming (MIP), and its merits and effectiveness are demonstrated using the standard IEEE 118-bus system.
