Lightning surge analysis for hybrid wind turbine-photovoltaic-battery energy storage …

The main reason is that the lightning surge transmitted from PV panel to the transformer is distorted. The winding has a high impedance, and the electromagnetic coupling effect is very small. Consequently, the surge mainly threatens the equipment within PV system, and has a relatively small effect on other parts of the hybrid substation.
