This study has developed metrics to evaluate the impact of intermittent renewable generation on the electric load demand that must be balanced by dispatchable generation resources, allowing examination of the general impacts of accommodating high renewable penetration levels. The metrics focus...

Hydroelectric generation has the ability to buffer intermittent renewable generation. The objective of this paper is to explore the changing roles of hydropower and pumped storage dispatch in response to increasing renewable penetrations. A novel aggregate model of hydro resources in the state...
