Lightning Strike Impacts on Hybrid Photovoltaic-Wind System

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.

Geomagnetic Induced Current Measurement in Hybrid PV-Wind System Transformers

“…The current control technique is used to design a grid-connected inverter control system. The required parameters of a single unit PV system are presented in Table. 1 [13][14][15][16].…”

Multi-objective wind farm layout optimization using evolutionary computations

“…Parallelization approach can speed up the computation process and furthermore it can improve in future. Although here they consider a selected wake model (Park Wake model), and it is important that the optimized algorithm is very easy to applied to the different "Wake models" (such as the deep array 'wake model' [14]). Michele S. et al [15] describes the "WFLOP" (wind farm layout optimization problem), which is critical problem that is necessary to solved during wind farm design.…”
