Assessment of demand response possibilities by means of voltage control with intelligent MV/LV distribution substation

Demand response is considered as one of the possibilities, which should help to keep our power systems in balance of generation and production. To keep the system balanced will become more difficult, when large shares of electricity are generated from intermitted renewable resources. The availability and response speed of demand response are going to be the crucial factors enabling the integration into the future power system as a reliable option. Therefore, taking into account those factors, the possible demand response by the means of local voltage control is proposed in this paper. The constraints and the availability of the proposed new demand response tool are addressed in this paper and are underpinned with results from a field test experiment with experimental MV/LV substation allowing local implementation of voltage control.
