Abstract
Study the impacts of lightning-induced transient overvoltage on a hybrid PV-Wind system has
been addressed in this work. Overvoltage that is generated due to lightning stroke travels along the system
where it can be very harmful to the expensive equipment of the system such as PV models, inverters,
charge controllers, batteries, transformers, and generator etc. The simulation model of a system has been
completed by using PSCAD/EMTDC software. The system comprises of 2 MW PV farm, battery system,
2.1 MW wind farm and loads which are all connected to the common AC bus and then to the utility grid
through an interfacing transformer. Lightning current is generated by using the double exponential
function, from the simulation results, when the lightning current is injected to the AC and DC sides of PV
system, the transient current and voltage have appeared at different points of the hybrid system. The
results were obtained for 8/20 μs and 10/350 μs standards lightning waveforms with current magnitude of
100 kA.
