Smartgrid, Microgrid

Microgrids must comply with national and international electrical and safety standards. Grid Simulators and bidirectional DC power supplies replicate real-world voltage, frequency, and load conditions, including anti-islanding and grid interactions, helping engineers ensure performance, reliability, and grid compliance to IEEE1547 /UL 1741SB at the component and system level.

Solar PV Inverters

PV inverters output AC power, so the grid simulator must absorb and return it. Pacific Power Source’s programmable AC Power Sources emulate AC anomalies for testing and certifying high-power grid-tied PV inverters. Simulate a wide range of AC anomalies for type testing and certification of large industrial PV inverters from 12 kW to several hundred kW.

Energy Storage Systems and V2G Testing

Validating vehicle-to-grid (V2G), vehicle-to-home (V2H), and vehicle-to-everything (V2X) is expanding to leverage EV energy storage for grid support. Pacific Power Source AC Loads and Grid Simulators enable bidirectional power flow and testing of complex load profiles. Our 2-in-1 Regenerative Grid Simulators emulate grid conditions and can also simulate inductive, capacitive, or resistive loads.

Transformer Testing

Transformers are tested to ensure they reliably step voltage up or down and operate safely under varying loads. Modern programmable AC power sources provide precise voltage and frequency control, allowing manufacturers to evaluate efficiency, voltage regulation, temperature rise, and overall performance. Compared to legacy methods like motor-generator sets, they offer greater accuracy, flexibility, and productivity, ensuring reliable, high-quality transformers.
