Diakoptics and system operations: automatic generation control in multiareas

Abstract

A procedure for the instant-by-instant control of all the generation, or the so-called automatic generation control, of power pools is described. The multicomputer configuration formed by the multiplicity of individual company computers present is utilised in the procedure. The method is an extension of the present basepoint-and-participation-factor approach used in the USA for the control of the generation in a single area. The paper first summarises the single-area method, and then presents the necessary multiarea theory; this is followed by the multiarea-dispatch algorithm and the procedure for the automatic generation control of power pools. It is shown that the hierarchy of multilevel control can be readily extended to a multiplicity of power pools or so-called ‘superpools’.
