Efficiency of energy conversion for a piezoelectric power harvesting system

This paper studies the energy conversion efficiency for a rectified piezoelectric power harvester. An analytical model is proposed, and an expression of efficiency is derived under steady-state operation. In addition, the relationship among the conversion efficiency, electrically induced damping and ac–dc power output is established explicitly. It is shown that the optimization criteria are dif...

A Hybrid Virtual Reality Simulation System for Wave Energy Conversion

A Note on Efficiency for Conversion of Light Energy.

A few years ago I gave a method, mainly based on the second law of thermodynamics, for calculating the maximum efficiency with which light energy can be converted into so-called high grade energy such as work or Gibbs free energy (1) [cf. also (2)]. This efficiency approached zero with decreasing light intensity and with increasing temperature of the system for conversion of light energy. An es...

Optimal Control of a Variable-Speed Wind Energy Conversion System: A New Approach

The operation of wind energy conversion systems mainly deals with variable and unpredictable wind regimes resulting in variable power efficiency. In addition, nowadays with the presence of high penetration level of wind farms integrated to power systems, stability and power quality problems might be addressed, when a disturbance event occurs. These challenges are worsened with significant degre...
