Abstract


Microgrids at the scale of a distribution feeder can provide an opportunity for communities to improve local electrical service and reliability. In particular, microgrids utilizing a combination of photovoltaic (PV) power generation and battery energy storage have gained increasing interest in Puerto Rico in recent years. This paper provides an overview of two voltage studies used to inform decision-making for the development of a feeder-level microgrid in Salinas, Puerto Rico. The studies explore options for using existing distribution line equipment from the utility and islanding portions of the line and utilizing different volt-var control parameters for different PV addition scenarios. While preliminary, the results of these studies can further inform the design and implementation of the microgrid.
