摘要：

The grid-connected PV system with BESS has been in use for many demand-related issues. This paper discusses the use of grid-connected PV in case of open phase condition in the distribution system. An Open phase condition at medium voltage (11 kV) will result in the reduced voltage at low tension (LT) voltage level (400 V) which may be detrimental to constant power loads connected to it. This paper presents an approach to mitigate such scenario by using VSC terminal of grid-connected PV with the distribution transformer (DT). The usefulness of the proposed configuration is validated by restoring the voltage in all phases at the LT level during an open phase at MV level. A MATLAB/SIMULINK model is developed and results obtained for a different mode of operation has been presented.
