Evaluation of the Oahu electric grid's stability and dynamic performance during contingency events with increasing levels of distributed photovoltaic solar resources. Analyses include the effects of generator trip and load rejection contingency events, transmission faults, and grid strength on system stability, including the identification and impacts of potential mitigations.

This study also creates a composite frequency stability metric that can quantify the level of risk to major system disturbances over all hours of the year from production cost simulations, in contrast to traditional methods that typically evaluate only a few hours based on potentially challenging system conditions. This approach also better informs long-term planning analyses.
