Gridco Systems, a supplier of end-to-end hardware and software systems for dynamic, distributed and decoupled power control, has announced the results of field trials of its emPower Solution system with multiple North American utility partners.

Used in several key grid-side applications, including integration of solar photovoltaics (PV), other Distributed Energy Resources (DER), increased energy efficiency and peak demand reduction as part of CVR/VVO initiatives, and power quality assurance, the system provides a means to increase PV hosting capacity, expedite PV interconnections, and is capable of doubling energy efficiency and peak reduction savings, its developers say. It is typically less than half the cost of business-as-usual approaches, such as reconductoring or asset replacement, and provides feeder- and system-wide benefits, they add.

Sacramento, California’s Municipal Utility District (SMUD) deployed and tested several IPR-50s to help with integration of the growing number of rooftop PV systems. The IPR’s dynamic and continuous voltage regulation under forward and reverse power flows enabled SMUD to maintain delivered voltage levels under a range of conditions.

TJ Vargas, Advanced Technology Engineer on the project, said: ‘SMUD finds significant value in more visibility and control of power flows at the edge of the grid from our increasing amount of distributed and variable renewable generation sources’.
