The operation and control of large interconnected power systems

The theory of tearing, also known as diakoptics, is applied to the problem of economy-security control of generation in power pools and in superpools. Power pools consist of individual utilities that join together to produce an optimal allocation of generation subject to the security constraints on the system. There are at present a number of power pools in the United States. Superpools consist of a multiplicity of power pools. Multiarea and multipool procedures are presented for the real-time control of generation in pools and in superpools using the hierarchy of computers present in the operations of individual utility companies. Other applications of diakoptics to power systems are summarized.
