Operating reserve assessment in interconnected generating systems

It is shown that the two risks concept can be used to determine the spinning reserve requirements of a multiarea interconnected system configuration. This is a probabilistic technique which takes into account the system parameters which directly or indirectly influence the system reliability. It is concluded that the use of a single system risk and an interconnected system risk provide valuable insight into the benefits of interconnection. These concepts are illustrated by application to two radially interconnected power systems. >
