Touted as an end-to-end hardware and software system for dynamic, distributed and decoupled power control, the solution is being used in several grid-side applications, including for reliable integration of solar photovoltaics (PV) and other distributed energy resources (DER), for increased energy efficiency and peak demand reduction as part of CVR/VVO initiatives.
Sacramento Municipal Utility District (SMUD) selected to deploy and test several IPR-50s to help with integration of the increasing number of rooftop PV systems.
The IPR’s continuous voltage regulation under forward and reverse power flows enabled SMUD to maintain delivered voltage levels under wide range of conditions, the company claimed.
Greater Sudbury Hydro distribution electrical systems vice president Brian McMillan said: "We needed to ensure the reliable delivery of power within CSA limits, especially to customers with voltage-sensitive equipment, and the Gridco Systems IPR-50 helped us achieve this goal.
"We are also using the IPR to maintain near unity power factor and cancel voltage and current harmonics, which have been getting worse over time due to the large amounts of customer-connected non-linear loads and electronics-based power supplies."
