New Phenomena in Bulk Power System Control
Abstract:
With the increasing penetration of renewable variable generation resources, many new system impacts have been observed, whereas well-known power system control tasks require significant rethinking and revisions. This short presentation attempts to review some of these phenomena and briefly analyze their possible solutions. Particular attention is paid to increasing interconnection balancing needs, overgeneration problem, tail events, frequency control, control of interchanges and congestion management, generation reserves and their flexibility, energy storage, incorporation of uncertainty information into system dispatch and coordination among Transmission System Operators (TSOs). The presentation outlines several new approaches to mitigate the impacts of renewable generation, including the concept of performance envelopes, wide-area energy management systems, security region concept, and others.
