In many power systems around the world, a major transformation is underway. Proportions of synchronous generation, generally from coal and gas-fired power plants, are rapidly reducing. At the same ...

One concern some observers raise about the growth of inverter-based resources, such as solar, wind, and battery storage, supplying the power grid is that they don’t provide inertia. Inertia has ...

Massive integration of inverter-based renewable energy systems has been displacing conventional generating units (mainly synchronous generators) and causing a reduction in power system inertia. This ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding interconnections, and increasing dependence on distributed energy ...

Energy markets are undergoing some massive transitions. Growing demand for electricity, when combined with the need to limit carbon emissions, drives a huge increase in renewables. This growth is ...

Many voltage regulators are of the fixed output variety and include the voltage divider internal to the regulator. There are definite advantages to this approach, which allows active voltage trimming ...

For decades, electricity regulators have treated tight control of grid frequency as a basic sign of power system security. If the frequency stayed close to the nominal value, the system was considered ...
