Unit commitment in interconnected generating systems using a probabilistic technique

A probabilistic technique is presented which can be used to develop unit commitment schedules for continually changing loads in an interconnected power system configuration for a specified period. The technique is developed on the basis of each area in a multi-area configuration fulfilling one of two different risk criteria. This approach, which is known as the two-risks concept, was illustrated in a recent publication (R. Billinton and N.A. Chowdhury, see ibid., vol.3, p.1479-87, 1988). The unit commitment during a specified scheduling period is constrained by risk criteria and economic factors. Typical unit commitment cases are illustrated with numerical examples.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
