Generation curtailment to manage voltage constraints in distribution networks

The issue of congestion management in distribution networks by considering a methodology for generation curtailment due to voltage constraints is addressed. The curtailment is based on the contribution of generators to the constraints as quantified by voltage-sensitivity factors. It has been shown that generation curtailment following a simple proportionality rule is not efficient and some alternatives, which give a more efficient outcome, have been proposed. Influence of network losses on the curtailment rules has also been shown. The considerations have been illustrated using two simple 11 kV networks.
