Modern trends in power system protection for distribution grid with high DER penetration

Increasing renewable penetration and grid modernization initiatives are having a significant impact on the operating fault characteristics of distribution systems. As result, protection systems need to account for changing nuances in transient response disturbances resulting voltage and/or current ensure safe reliable operation. The approaches modeling analyzing power also evolve accordingly, based choice system. Therefore, this paper reviews state-of-the-art evolving future energy categorized principles variations underlying mathematical formulation – present comprehensive overview detection recommendations research. nature systems, interconnection requirements standards, system automation is discussed view higher fidelity models limitations from approaches. Finally, algorhithms compared their associated challenges with reliability, protection, communication/design needs.
