Special Issue Information

Dear Colleagues,

Climate change due to greenhouse emissions and the depletion risk of traditional fossil energy resources are two great challenges faced by human society. The use of renewable energy sources in energy supply has been indexed as a solution and has been growing rapidly in recent years. Despite the massive deployment of renewables, they still face major barriers to wider adoption. Some are associated with renewable energy technologies, while others are due to the modern energy market and regulatory and infrastructure realities.

This Special Issue aims to collect high-quality papers in renewable energy applications and thus create a space where readers can find renewable energies engineering critical reviews on methods, solutions, and applications, helping to strengthen cross-field cooperation mechanisms to boost the deployment of enabling renewable energy technologies. In this context, researchers are encouraged to submit manuscripts on innovative technical developments, reviews, case studies, and analytical as well as assessment papers from different disciplines, which are relevant to renewable energy applications and the renewable energy market: marine current turbines, wave energies, offshore wind turbine technologies, sensing and monitoring systems, subsea engineering, hybrid generation systems, and smart grids.

Grid-connected inverters are the core equipment for connecting marine energy power generation systems to the public electric utility. The variation of current sensor fault severity will make fault samples multimodal. However, linear discriminant analysis assumes that the same fault is independent and identically distributed. To solve this problem, this paper proposes a layering linear discriminant analysis method based on traditional linear discriminant analysis. The proposed method divides the historical fault data based on the sensor fault severity layer-by-layer until the distribution of the same fault category in each subset is very close. Linear discriminant analysis is used to analyze historical fault data in each subgroup, and the kappa coefficient is applied as the basis for ending the training process. A BP neural network is employed to estimate the fault severity during the testing process, and the fault diagnosis sub-model is selected. The proposed method enables the accurate diagnosis of faults with different distributions in the same category and provides an accurate estimate of the sensor’s fault severity degree. The estimated value of the sensor’s fault degree can provide critical information for the maintenance of the equipment and can be used to correct the sensor’s output. Full article
