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 ...

As more renewable energy sources and battery storage units are specified and incorporated into power systems, consultant specifying engineers are faced with many challenges that could impact the ...

Cutting edge battery storage technology designed to provide crucial grid balancing services that are traditionally the preserve of fossil fuel power plants will be showcased in Tahiti, in a project ...

Grid-forming inverters can operate independently, maintaining voltage and frequency during grid outages, unlike grid-following inverters that rely on external signals. Adoption of GFM technology ...

The newly expanded Hornsdale Power Reserve, aka the Tesla big battery, has reported a successful “real life” test of its new “virtual machine mode” when it reacted to the grid disturbances created by ...

As more wind and solar generation is added to the power grid and large coal and nuclear plants are retired, a reduction in reactive power is becoming a concern. Underutilized gas and steam turbines ...

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, ...
