PROJECT TITLE :
Enhanced Aging Model for Supercapacitors Taking Into Account Power Cycling: Application to the Sizing of an Energy Storage System in a Direct Wave Energy Converter
This paper proposes an ingenious model for supercapacitors that takes under consideration each calendar aging and cycling aging. A state variable is used to quantify the state of aging. This model relies on a series of recent experiments conducted in numerous analysis laboratories on the identical technology (Maxwell Technology) and serves to represent the degradation of equivalent series resistance and capacitance. This model is particularly helpful in an aging-aware life-cycle price analysis. We have a tendency to show that an accurate aging model is essential to the look of an energy storage system that optimizes the economic life-cycle price. Such an optimization is notably applicable for smoothing in offshore systems such as direct wave energy converters, which need both value reduction and high reliability. The influence of an aging model in the sizing process is investigated toward the top of this paper.
