Synopsis: Uniquely correlating the increased number of larger and longer-lasting frequency excursions in North American Interconnections with electricity market design and frequency control regulations, the report connects direct (technical) and indirect (non-technical) causes, both the physics of the problem and the regulatory environment (i.e., regulations, standards, and policies). The physical laws governing the frequency stability phenomenon and system control efforts are responsible for maintaining the nominal system frequency. However, the regulatory environment impacts policy on market design, affecting frequency stability and policies directly affecting frequency control practices. The report covers both technical and policy aspects to improve frequency stability.
