"Optimal Sizing of Renewable Energy-Based Charging Infrastructure for E" by O. M.Alshateri Ahmed, S. B. Wali et al.

The availability of electric vehicle (EV) charging facilities is crucial to the EV application, which is a promising solution to minimize fossil oil consumption and greenhouse gas (GHG) emissions. Nevertheless, satisfying EV charging requests through the electric grid might result in grid destabilization owing to a rapid spike in load profile. The effective implementation of an optimized renewable energy (RE)-based hybrid energy storage system (HESS) can reduce the sudden impact of EV charging on the grid, can diminish the increased power demand from the utility grid, and reduce the GHG emission. This article has proposed an optimal solution for HESS-integrated EV charging stations (CSs) in Riyadh, Saudi Arabia. Three different HESS configurations such as; grid-dependent system, off-grid PV-wind-battery energy storage system (BESS)-based system, and grid-connected PV-wind-BESS-based system for EV charging stations are designed and investigated. The simulation results are analyzed consi ....

"Techno-economic feasibility analysis of Renewable-fed Power-to-Power (" by Zaib Shahid, M. Santarelli et al.

In this paper, the feasibility analysis of H2 and Battery based Power-to-Power (P2P) systems are presented from a techno-economic perspective. For this study, 21 small islands of France based in Europe are selected, being naturally endowed with renewable energy sources (RES) of solar and wind. For each island, three distinct energy storage options, i.e., hydrogen storage, battery storage and hydrogen + battery combined storage are discussed and explored. Optimum sizing of RES and P2P systems are achieved through employing particle swarm optimization (PSO) algorithm, keeping Levelized Cost of Energy (LCOE) as an objective function. The hydrogen and battery storage combination with an average LCOE value of 420Euro/MWh was found to be the most suitable option for all 21 reference islands. The associated Net Present Cost (NPC) was EUR564,388,050 which was lower than that for the other two storage options. The hybrid storage selection necessitated installation of 41 MW of photovoltaic (PV) ....
