Traditionally, the electrical grid was designed with high voltage power generation stations, substations to convert to lower voltages and consumption mainly in the low voltage grid. Problems now arise in the low voltage grid with the increased and often simultaneous power generation by e.g .solar panels and wind turbines. Other problems arise on the consumption side from big consumers like electrical cars that often start charging simultaneously when people arrive at their destination. The low voltage network is not dimensioned for these fluctuating power loads, and upgrading all cables woul4d involve enormous costs, therefore we are looking for smarter ways to tackle these issues.
The EU H2020 project UNITED-GRID (Integrated cyber-physical solutions for intelligent distribution grids with high penetration of renewables) started in November 2017 for 3.5 years.
The UNITED-GRID project objective is to develop technical solutions to serve needs and opportunities for distribution system operators (DSOs) in their electricity grids. The project, carried out from November 2017 to April 2021, has received funding from the European Commission’s framework programme Horizon 2020.
SST participates in this project to provide highly synchronized distributed phasor measurements for LV voltage and current to facilitate state estimation, power quality and self-healing grid algorithms.
