Optimization of the Piezoelectric Wave Energy Converter Device

Comprehensive study on “wave energy converters (WEC)” that transform wave energy into electricity is mandatory to strengthen the economic viability of wave energy, one of the biggest and most potential renewables. In the not-too-distant future, improved hydrodynamic performance ought to allow wave devices to perform equally well with traditional power stations. The current study addresses the hydrodynamics of the breakwater integrated “piezoelectric wave energy converter device (PWEC)” positioned over the uneven seafloor. To handle the present “boundary value problem (BVP),” the “boundary element method (BEM)” is implemented. The influence of the different incident wave and shape factors linked to the PWEC device and uneven seafloor on the “power extraction” by the “piezoelectric plate” is discussed in extensive manner. The study found that when the plate is located nearby the free surface and has a moderate plate length, PWEC extracts more power. A multi-factor optimization depends on the “Taguchi method” is presented and it is noticed that the system 1 has outstanding bandwidth and power extraction.
