HYBRID LIGHTNING PROTECTION DESIGN FOR WIND–SOLAR RENEWABLE ENERGY SYSTEMS UNDER EXTREME WEATHER CONDITIONS

Abstract

Background: Hybrid wind-solar renewable energy systems (HRES) are becoming more popular as a means of generating renewable energy in a sustainable way. Nonetheless, lightning strike is susceptible to these systems particularly during extreme weather conditions and it presents a danger to equipment and operational dependability. Direct and induced lightning strike damage should be minimized by proper lightning protection.

Purpose: The purpose of the study is to create a hybrid type of lightning protection in wind-solar energy systems to increase the resiliency of the device to extreme weather conditions and lightning-related damages.

Procedure: The study employs a risk-based analysis, which involves simulations and field experiments to develop and test a lightning protection system. Mathematical modeling of the electrical and electromagnetic behavior of the system is done using simulation tools such as MATLAB/Simulink and COMSOL Multiphysics. Field tests are done to test the design performance against the reality that includes transient voltage suppression and surge protection.

Findings: The findings demonstrate that combined measures of lightning protection, such as surge protecting devices (SPDs), air terminals, and optimized grounding systems can significantly decrease downtimes of the systems and maintenance expenses. Field tests proved that the control system reduced downtime by 90% and the maintenance cost of the system by 35%.

Conclusion: The proposed hybrid design of lightning protection is effective in mitigating lightning hazards, which guarantees wind-solar systems long-term and safe operation during extreme weather conditions.
