OU has been awarded a $4.5 Million grant plus $1.7 Million cost-share from industry partners to study solar photovoltaic system integration into distribution feeders. The work will focus on new power system protection techniques to contend with new transient disturbance features generated by faults propagating in grids with high penetration inverter-based energy resources. OU is leading a consortium to develop a world-class power system protection testbed to prototype new protective relaying and fault management scenarios.
