Recent electrical utility power system outages indicated the need to reinforce the power system at the NASA Glenn Research Center. Modern photovoltaic (PV) panels and electronics have made grid-tie power systems safe, reliable, efficient, and economical with a life expectancy of at least 20 years. In fiscal year 2006, Glenn designed, developed, and installed a state-of-the-art grid-tie PV power system that is providing power to Glenn’s power grid so that it is available for use by all. The project was proposed by the Avionics, Power, and Communications Branch of Glenn’s Engineering and Systems Division to Glenn’s Facilities Division as follows:
The project transfers space technology to terrestrial use via nontraditional partners, and it provides power system data valuable for future aero-nautics and space applications. The work was done under the Hybrid Power Management (HPM) Program. HPM is the innovative integration of diverse, state-of-the-art power devices in an optimal configuration for space and terrestrial applications. The appropriate application and control of the various power devices significantly improves overall system performance and efficiency. Applications include power generation, transportation systems, biotechnology systems, and space power systems.
The HPM Program has been applied to Glenn’s electric utility system through a grid-tie PV power system.
There are many benefits to the grid-tie PV power system:
The grid-tie PV system has operated flawlessly since operation began. The system performance has been excellent, and expansion of the system is under consideration.
