Unlike the fixed wind turbines, structure of Floating Offshore Wind Turbines (FOWT) have added motions six degrees freedom induced by wind, wave and tidal loads. These lead to vibration degradation structure. This paper presents a novel approach model stabilize FOWT employing Oscillating Water Columns (OWC) as active structural control system. The innovative concept involves designing new floating barge-type platform with integrated OWCs on opposite sides mitigate undesired oscillations counteract bending forces caused tower waves barge platform. To synchronize opposing system's tilting, proposed Particle Swarm Optimization Decreasing Inertia-based Adaptive Neuro-Fuzzy Inference System (PSODI-ANFIS) airflow strategy is employed. Through manipulation platform's pitch angle, PSODI-ANFIS system adjusts valves either side, opening one closing other accordingly. Simulation results, compared standard well Fuzzy-based system, demonstrate effectiveness control. It shown be superior in reducing pitching fore-aft translation top tower.

Floating wind-integrated PV system yield analysis considering AHSE dynamics & solar azimuth effects

Energy Conversion and Management, Journal Year: 2024, Volume and Issue: 315, P. 118799 - 118799

Published: July 14, 2024

Floating Photovoltaic (FPV) systems face dual challenges of structural reliability and high electricity costs in offshore deployments, hindering their widespread adoption. Integrating FPV with Offshore Wind Turbines (FOWT) offers a promising solution to these challenges. A hybrid wind-solar system is proposed, leveraging mathematical modelling simulation, inheriting dynamic states from FOWT employing shared DC bus for power generation. Key findings reveal reduced variation as solar elevation angle increases, photovoltaic efficiency declining near the complementary PV tilt offset. The demonstrates resilience platform movements, ensuring over 97% even under significant wave heights. Additionally, greater pitch motion enhances effects between wind energy. proposed offset control strategy effectively compensates fluctuations, particularly at lower azimuth angles higher angles. Real-world based simulation Taiwan Strait validates findings, emphasizing potential coupled platforms optimizing renewable energy performance coastal regions.

Wind energy is crucial in mitigating greenhouse gas emissions and combating global warming. However, the economic viability of wind projects tied to resources, which may be affected by climate change. The objective this work investigate evolution resources South America using most up-to-date climate-change scenarios: Shared Socioeconomic Pathways. Three scenarios are considered, corresponding low, medium high pathways. A multi-model ensemble constructed with Global Climate Models selected for their accuracy study region a historical period. Results indicate that east Andes, Brazil, Paraguay Venezuela, substantial increases average power density expected, surpassing 100 % certain areas pessimistic scenario (the fossil-fuelled development pathway). By contrast, significant reductions (up ~50 %) projected west Andes: Chile, Peru waters off West Colombia. Chile has windiest continent, makes reduction due change all more important. Even under low-emissions scenario, relevant, highlights necessity considering planning.
