Guaranteeing uninterruptible power supply is of paramount importance for critical infrastructure like hospitals, industries, state parks and military sites. This objective becomes challenging when the critical facility is in a rural location, at the end of the feeder and/or is prone to frequent weather hazards. This leads to situations whereby the time required to restore power to the customers during outages can take even upto a few days, in some cases. This is primarily because it's difficult to economically justify employing traditional reliability improvement techniques like vegetation management and installing underground cables in rural locations which are usually sparsely populated large geographical areas. One of the approaches to improve resilience at remote rural communities is to employ microgrids that provide electric service capacity during blackouts. Once the microgrid is designed to meet the minimum reliability target of the critical facility, it can also be used for other secondary applications which increase the economic value that the microgrid offers to the customer.
