Risk constrained economic load dispatch in interconnected generating systems

A risk-constrained unit loading technique for interconnected systems is presented which utilizes a least-costly deviation for economic load dispatch to satisfy the risk criteria. The technique is developed on the basis of each area in a multi-area configuration fulfilling one of two different response risk criteria. The technique is illustrated with numerical examples. Risk-constrained economic loading schedules have been developed using reloading steps of 1 MW and 5 MW. In an actual system, other reloading steps should be tried in order to meet the specific needs of the system in terms of operating economy and computation time
