The need for lithium-ion battery degradation studies arises due to the ever increasing use of these...

Electrification of a bus system with fast charging stations: Impact of battery degradation on design decisions

In this paper, we evaluate the cost of the electrification of an existing bus network. We propose a family of bi-objective mathematical models to demonstrate the trade-off between strategic (i.e., battery sizing and the locations of charging stations) and operational decisions (i.e., battery degradation). The proposed mathematical models...

Besides optimally dimensioning the components, it also optimizes power management while...

Implementation of smart charging algorithm with V2G services considering its effects on battery degradation

Electric vehicles (EVs) are going to take over the conventional cars industry like a wave in the foreseeable future. The exponential increase in sales of EVs is seen and market study has predicted that EV sales will increase by 15%–20% of total new vehicle sales by the year 2035. Despite being superior to fuel-driven vehicles, the increase in...

Modeling economic sharing of joint assets in community energy projects under LV network constraints

The trend of decentralization of energy services has given rise to community energy systems. These energy communities aim to maximize the self-consumption of local renewable energy generated and stored in assets that are typically connected to low-voltage (LV) distribution networks. Energy community schemes often involve jointly owned assets...
