Special Issue Information

Dear Colleagues,

In recent years, there has been an important international movement towards reducing dependence on fossil fuels, with greater emphasis placed on the promotion of sustainable renewable technologies for electricity generation in order to reduce greenhouse gas emissions. To this end, bearing in mind that the oceans are the largest collectors, accumulators and transformers of energy on earth, marine renewable energy systems are expected to penetrate conventional power supplies as part of the pursuit of carbonless energy systems before 2050. 

This Special Issue aims to showcase the latest research achievements, findings, and ideas in the renewable and sustainable utilization of marine renewable energy. Researchers are invited to contribute original research articles, as well as review articles that summarize the latest developments and ideas in these technologies.

Potential topics include, but are not limited to:

  • Possibilities of marine renewable energy development;
  • Renewable marine energy sources, institutional factors, and sustainable development;
  • Marine renewable energy and energy demand of the residents;
  • Energy conversion;
  • Energy security;
  • Pro-ecological marine technologies.

Due to the influence of meteorological conditions, shipboard photovoltaic (PV) systems have problems such as large fluctuation and inaccurate prediction of the output power. In this paper, a short-term PV power prediction method based on a novel digital twin (DT) model and BiLSTM is proposed. Firstly, a PV mechanism model and a data-driven model were established, in which the data-driven model was updated iteratively in real time using the sliding time window update method; then, these two models were converged to construct a PV DT model according to the DS evidence theory. Secondly, a BiLSTM model was built to make short-term predictions of the PV power using the augmented dataset of the DT model as an input. Finally, the method was tested and verified by experiments and further compared with main PV prediction methods. The research results indicate the following: firstly, the absolute error of the DT model was smaller than that of the mechanism model and the data-driven model, being as low as 5.62 W after the data update of the data-driven model; thus, the DT model realized data augmentation and high fidelity. Secondly, compared to several main PV prediction models, the PV DT model combined with BiLSTM had the lowest RMSE, MAE, and MAPE; the best followability; and the smallest absolute error under different weather conditions, which was especially obvious under cloudy weather conditions. In summary, the method can accurately predict the shipboard PV power, which has great theoretical significance and application value for improving the economy and reliability of solar ship operation.

This study utilizes a bidirectional fluid–structure interaction numerical method to investigate the hydrodynamic and energy harvesting characteristics of two tandem three rigidly connected cylinder oscillators with different inter-oscillator spacing ratios. The analysis considers inter-oscillator spacing ratios of 8, 12, and 16 within a reduced velocity range of U* = 2–13 (equivalent to flow velocities of 0.18–1.16 m/s). The research explores the hydrodynamic interference features, energy harvesting variations, and the efficiency and density of energy harvesting of both upstream and downstream three-cylinder oscillators. The findings indicate that with increasing reduced velocity and inter-oscillator spacing ratio, the mutual interference between upstream and downstream oscillators diminishes. Wake patterns observed in the two series-connected three-cylinder oscillators include 2P, 2S, and 2T patterns, with fragmented vortices and banded vortices at specific reduced velocities. The most significant disparity in energy harvesting efficiency between upstream and downstream oscillators is observed at U* = 9. Full article
