This white paper describes preliminary research on the use of progressive control strategies to improve the advanced electric power grid’s resilience to major grid disturbances. The proposed approach calls to leverage real-time wide-area monitoring and control capabilities to provide globally coordinated distributed control actions under stressed conditions. To that end, the paper illustrates the proposed concept using case studies drawn from major North American blackouts, discusses design challenges, and proposes the design of a Grid Integrity Management System (GIMS) to manage the required communication and computation to meet these challenges.
