Georgia PSC Approves 500 MW Battery Storage Plan

The Georgia Public Service Commission (PSC) has approved a significant expansion of the state's energy storage infrastructure, green-lighting a plan for Georgia Power to install 500 megawatts (MW) of battery energy storage systems (BESS). This decision marks a major step forward in the state’s transition to more reliable and sustainable energy sources.

The 500 MW of battery storage will be distributed across several locations throughout Georgia, including co-located sites at existing solar farms and retired...

Utilizing Fault Resistance to Test Distance Relays

Taking power grid protection to an all-new level

BY JASON BUNEO & RENE AGUILAR, Megger

The testing of distance relays has evolved from testing simple electromechanical relays to the newest modern microprossesor relays. Most modern relays employ advanced algorithms that not only compare the direction of voltages and currents in the system but also rather look at other system components. For example, many modern relays utilize various methods in order to determine the direction of the fault such as negative sequence impedance, zero sequence impedance, cross polarization, and others. This is only one of the many parameters that make up the distance protection.

Due to this increase in complexity in distance relays, the test methods have also evolved from the simple traditional methods of injecting simple arbitrary test values to requiring more realistic test values. It is important to understand how these newer devices function in order to be...
