SmartCityVillach: Final results of field test validation of a voltage estimation application that supports distributed voltage control in times of communication loss

This paper presents estimation strategies for voltage measurements developed to enhance the robustness of distributed voltage control in secondary substations in case of communication delays and failures. Different estimation concepts are described and benchmarked. The most promising concepts were implemented and validated in field tests in two low voltage grids for several months. Results from these field experiments and underlying simulations are shown and the impact of the estimation concepts on the voltage control process is discussed.
