Interconnection modelling of power systems

Abstract
Mathematical models are required to calculate tie flows for allocating generation among groups of interconnected companies, for costing and cost reconstruction of power interchanges between companies or pools, and for a variety of security functions. This paper presents new procedures for modelling the many ties between groups of interconnected power companies. The systems whose interconnections are modelled can represent one pool or a multiplicity of power pools, typical of U. S. systems. Novel procedures of constructing the interconnection models are described, including the automatic formation of topological matrices which define the circulating and interchange paths existing in the interconnections. The models can be used in both off-line studies and in real time operations of power systems. Results are represented verifying the development.
