Modelling of series and multiple shunt compensators to minimise power losses in Photovoltaic integrated power distribution networks

This paper provides an approach to model a single series and multiple shunt compensator for the Photovoltaic (PV) integrated distribution network. The series compensator (SEC) is designed to mitigate voltage sag in the network. The shunt compensator (SHC) is modelled to reduce the harmonic content in the line current by providing reactive power compensation to the network. Except for the substation bus, all the buses are considered to have initial placements of PVs in the network. The locations of the compensators are pre-determined. The sizes of the compensators are determined based on the modelling presented. The Forward-Backward Sweep (FBS) load flow algorithm determines the voltages and currents flowing through the distribution network. The study highlights the benefits of using both SEC and SHCs together to significantly reduce network losses and under-voltage nodes for the PV-integrated distribution network.
