An improved economic framework for power quality

This paper presented a subset of the results of research performed by EPRI examining and developing a "QRA method" for quantifying the reliability of electric power supply to end-user processes, and focusing on determining overall cost of PQ events and mitigation costs. The QRA methodology provides a means to determine PQ mitigation approaches that optimize economic return by mitigating only the subset of PQ and reliability phenomena that can be cost-effectively resolved.
