The loss of excitation (LOE) in synchronous generators represents a critical fault condition that can lead to severe operational disruptions and damage within power systems. Under normal conditions, ...

A group of researchers in Australia has outlined a new methodology to determine the minimum power rating of energy storage systems (ESSs) used for emergency under-frequency response. The ESS size must ...

To get the best efficiency for my battery backup system I want to make sure that the backup battery is large enough to cope with at least twice the total amp hours required in my calculations. So, in ...

People in the power industry understand inertia and its importance to grid stability. As large thermal power plants and other inertia-providing units are replaced with renewable resources that provide ...

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 ...

Germany has connected the world’s first supercapacitor-based STATCOM to the grid, with Siemens Energy and transmission system operator TenneT positioning it as a blueprint to replace fossil-fuel ...

Global demand for electricity supply continues to grow. Power generation providers constantly evaluate capacity additions and the tradeoffs between alternatives. Since American utilities are building ...

It's about time to prepare for summer by selecting a home battery or generator that can make sure your air conditioning stays up and running. Batteries and generators provide the same basic service, ...

With the colder months approaching, we face the possibility of power outages that can last from hours to weeks. Investing in a standby generator is one of the best ways to keep your most important ...

Fundamentally, electrical power is developed, delivered, and consumed as voltage and current. In a simple direct current (DC) device such as a flashlight, the power (the brightness of the bulb) is the ...

Microsoft Corp. said it has conducted a successful test of a large, three-megawatt hydrogen fuel cell system that could one day serve as an environmentally friendly backup power source in its data ...
