“…However, the impact of selecting the most suitable suppression technique with respect to the wind farm topology was not investigated before. Such topic is highly important as the degree of severity of the switching overvoltages (SOV) depends mainly on the wind farm topology 3,19,20 . Therefore, the main problem that this paper aims to address is to investigate the most suitable suppression measure for each wind farm topology.…”

“…For transient analysis, the effect of the stray capacitance is crucial to be considered. For such reason, the stray capacitances between each winding and the ground and the capacitance between the two windings of the main transformers were simulated using capacitive elements connected across transformer component upon ATP 3,26 .…”

Various overvoltage mitigation schemes were used in literature in suppression of switching overvoltages in wind farms. However, the evaluation of how the effectiveness of these mitigation techniques would vary with the change of the wind farm topology is still un-explored territory. The main aim of this paper is to study the effectiveness of four mitigation schemes namely; R-L smart choke, R-C snubber circuit, surge capacitor and pre-insertion resistor (PIR) were studied in four different wind farm topologies; radial, single-sided ring, double-sided ring and star topologies. The topologies were based on a real wind farm located in Zaafrana, Egypt. The results showed that R-L choke to be the most effective scheme for all topologies followed by PIR, R-C snubber and surge capacitor schemes respectively. Their percentage of reduction of overvoltage ranged from 62–84% for R-L choke, 33–67% for PIR, 8–25% for R-C snubber circuits and 4–15% for surge capacitors. Also, it was shown that the change of the wind farm topology didn’t affect the order of effectiveness of the mitigation schemes such that R-L remained the most effective and surge capacitor the least effective for all topologies.

“…Onshore wind farms are less expensive and more appropriate for operation than offshore ones. However, one aspect of all types is ensuring the wind farm is designed and planned as effectively as possible [3]. Further, measures must be taken to ensure the sustainability of the installed wind farms [4].…”

In this paper, the Wind Farm Layout Optimization/Expansion (WFLO/E) problem is formulated in a multi-objective optimization way with specific constraints. Furthermore, a new approach is proposed and tested for the variable reduction technique in the WFLO/E problem. To solve this problem, a new method based on the hybridization of the Multi-Objective Evolutionary Algorithm Based on An Enhanced Inverted Generational Distance Metric (MOEA/IGD-NS) and the Two-Archive Algorithm 2 (Two Arch2) is developed. This approach is named (MOEA/IGD-NS/TA2). The performance of the proposed approach is tested against six case studies. For each case study, a set of solutions represented by the Pareto Front (PF) is obtained and analyzed. It can be concluded from the obtained results that the designer/planner has the freedom to select several configurations based on their experience and economic and technical constraints.
