Abstract

We present a combined look-ahead dispatch and reserve optimization formulation, which extends our recent work on time-coupled reserve policies and employs the recent notion of generalized decision rules from the robust optimization literature. This aims to improve the performance of traditional linear decision rules when applied to short-term electrical reserve operation. We derive a primal problem whose solution is a time-coupled rule for up- and down-regulating the power injections of each controllable device, such as a generator or energy storage unit, in response to discovered values of prediction errors. This rule depends on the 'bin' into which measured prediction errors fall, so that,..
