Transmission Expansion Planning as a Dynamic MILP that Considers the Long Term Availability of Wind.

Abstract

Wind generation present some special features, such as the variability and intermittent availability of the wind resource, which may affect either short-term or long-term coordination of power markets. When considering wind power generation, an additional reserve is required for the secure market operation due to the variability introduced by wind energy. Only marginal units, ramp-rate constrained units, or reserve-providing units will likely be partially dispatched. Thus, the output of conventional generators can be potentially increased without changing the system marginal prices. Consequently, variations in wind output can often be compensated for by adjusting the outputs of the partially dispatched conventional generators.
