Rare-earth elements like neodymium, terbium and dysprosium are crucial to the performance of permanent magnets used in various green-energy technologies hybrid or electric cars. To address supply risk those elements, we applied machine-learning techniques design magnetic materials with reduced neodymium content without dysprosium. However, magnet intended be motors should preserved. We developed methods that assist by integrating physical models bridge gap between length scales, from...

The distributed solar generation possess the potential to overcome energy deficit in a power system network. However, its high penetration reshapes system's flow and causes fluctuations voltages frequency. To uncertainty variability issues faced by systems, storage plays vital role. In this paper, Electric Vehicles (EVs) are used as Demand Side Management (DSM) tool mitigate fluctuations. behaviour of EV's battery act load/source is controlled three parameters; State Charge (SoC), output...
Due to the increase in demand for electrical energy, integration of solar PV grid network is increasing at a great rate both developing and developed countries. However, majority countries have radial power distribution networks thus high penetration can cause over voltage problems. This paper discusses effects on end line bus voltages resulting losses network. A loop proposed solve problems capacity PV. Seven different scenarios been analyzed by placing system buses an IEEE-33 comparison...
In the pursuit of rare earth-lean permanent magnets for green technologies, microstructural optimisation offers a promising strategy to enhance coercivity while minimising critical element content. For this approach, combination experimental work on hard magnetic films and numerical investigations is necessary. However, computational limitations restrict micromagnetics small systems, motivating development reduced order model investigating large multigrain systems. The based embedded...
