Smart transformer for mitigation of voltage fluctuations in MV networks

This paper describes the application of the smart medium to low voltage transformer to increase the flexibility of distribution networks, support the accommodation of distributed generation and to attenuate the voltage fluctuations originating from medium voltage network. The theoretical framework is set and three possible control strategies are investigated and their performance to mitigate voltage fluctuations is compared. The most suitable control strategy is chosen on basis of performance and suitability for practical implementation. In addition, a new application of voltage control in low voltage network is proposed.
