Rapid deployment of photovoltaic (PV) systems means even more rapid growth of PV penetration on the grid. This brings many techno-economic problems to planning and operation of the grid, and as a result, utilities are increasingly limiting solar deployments due to its intermittency and impact on feeder voltages. Future problems of higher penetration will require all distributed generation to have utility-controllable capabilities for peak-shifting, regulation, and contingency reserve. Much progress towards “plug and play” PV has been made on the mechanical and labor aspects of PV installation. UCF researchers are working on a new distributed, scalable, and efficient PV-storage system that addresses many PV penetration concerns ahead of time, while allowing easy and cost-effective installation, maintenance, and operation. The advantages of local storage include: (1) Support of the grid (voltage regulation, frequency regulation and contingency reserve); (2) Load shifting and peak shaving; (3) Using excess converter thermal “headroom” for short-term emergency over-generation; (5) Minimizing transmission and distribution losses; (6) Optimizing local energy production and consumption.
