Abstract

The rising share of distributed generation (DG) in the power system results in reduced inertia and larger frequency deviations following power imbalance. Balancing efforts of transmission system will require increasing coordination of distribution networks. This paper analyses impact of different characteristics of Low Voltage (LV) networks on its power consumption when varying voltage at point of common coupling in order to support frequency containment of transmission system. Frequency support is delivered by adapting the LV grid voltage to shape power consumption of voltage-dependant loads. It enables the use of voltage as a trigger for active power control of 1 voltage-dependant loads without the need for additional communication and frequency measurement. The Smart Transformer allows a fast control of voltage amplitude, and consequently, power consumption of LV grid without affecting medium voltage grid. Different network characteristics were analysed to determine networks most suitable for providing frequency support through voltage control.
