Keysight Technologies introduces PHIL testing solution to reduce anti-islanding test times
Tuesday, March 24, 2026 at 02:40 AM
Keysight Technologies has introduced a Power Hardware-in-the-Loop (PHIL) testing solution designed to drastically reduce the duration of anti-islanding tests for power electronics from several weeks to just a few hours.
Context
On March 24, 2026, Keysight Technologies announced a breakthrough in grid compliance testing with its new Power Hardware-in-the-Loop (PHIL) solution. This technology is designed to automate anti-islanding tests for distributed energy resources (DERs), such as solar inverters and battery storage systems. By utilizing a patent-pending RLC autotuning algorithm within its SL1200A Series AC emulators, Keysight has reduced traditional test cycles from two weeks down to just four hours, representing a massive gain in engineering productivity.
This development is critical as the surge in AI-driven data centers and EV charging infrastructure puts unprecedented stress on global electrical grids. Ensuring that inverters can safely disconnect during power outages (anti-islanding) is mandatory for grid stability. By eliminating the need for bulky physical load banks and manual trial-and-error processes, Keysight is enabling manufacturers to accelerate the deployment of power semiconductors and renewable energy hardware required to meet the 4% to 9% rise in total electricity demand projected for major markets.
