Energy method of spinning reserve assessment in interconnected generation systems

A probabilistic technique for assessing spinning reserve requirements in interconnected systems has been published. The technique, the two risks concept, is based on capacity assistance and, therefore, does not deal with some of the essential system issues pertaining to unit size and lead time in a consistent manner as far as the spinning reserve assessment is concerned. An energy based technique to assess spinning reserve requirements in interconnected systems is presented. The proposed technique responds to unit size and lead time in a direct way. Two test systems and a hypothetical system are utilized to provide numerical examples
