Power generating units (PGU)
We evaluate and confirm compliance with critical electrical characteristics of PGU, including:
- Active and reactive power
- Low and high voltage ride through (LVRT/HVRT)
- Protection and control systems
- Power quality
PGU grid code compliance standards
UL Solutions provides testing and certification for a wide array of power generating units and components, such as:
- Photovoltaic (PV) inverters
- Wind turbines
- Energy storage power conversion systems
- Bi-directional EV chargers
- Combined heat and power generators
- Mini hydroelectric generators
- Synchronous generators
- Power plant controllers
Since 2016, European grid codes feature a common requirement based on European Regulation EU 2016/631 – Requirements of Generators. To streamline market access efforts, our team can bundle testing services for a variety of requirements including EU 2016/631, UL and IEC product standards as well as perform preliminary evaluation for grid code compliance for units and components.
