Todays requirements to load shedding schemes against cascading outages in electric power systems

Abstract The paper presents Russian experience of emergency control of electric power systems with accent to peculiarities of distributed and adaptive automation; analyses place, role and specificity of electric load disconnection as an emergency control action and load shedding scheme as an emergency control automation. Particular attention is paid to special load shedding scheme, its place in prevention of cascading emergencies, and prospects of its development as disaggregated, distributed and adaptive automation. On this base the requirements to the principles and algorithms of such automation action against stability loss and overcurrents of electrical network components are formulated.
