Journal ArticleDOI
Optimal Torque Control of Synchronous Machines Based on Finite-Element Analysis
TL;DR: Simulation and practical results show that the torque is controlled effectively in the entire speed range using this generic method, which relies on machine-specific data from FE analysis and therefore includes nonlinear effects such as saturation and cross coupling.
Journal ArticleDOI
Short-term solar power forecasting: Investigating the ability of deep learning models to capture low-level utility-scale Photovoltaic system behaviour
TL;DR: Results demonstrate a marginal increase in forecasting accuracy from the proposed aggregated inverter-level forecasts, and it is concluded that deep learning based macro-level forecast models have a sufficient ability to capture low-level PV system behaviour.
Journal ArticleDOI
Radial-Flux Permanent-Magnet Hub Drives: A Comparison Based on Stator and Rotor Topologies
A.J. Rix,Maarten J. Kamper +1 more
TL;DR: It is shown that the torque-per-copper-loss performance of the machine cannot be judged solely on the winding factor of themachine and wide open stator slot machines with rectangular preformed coils and, hence, low manufacturing costs are found to perform better than expected.
Proceedings ArticleDOI
Optimising Power System Frequency Stability Using Virtual Inertia from Inverter-based Renewable Energy Generation.
Warren J. Farmer,A.J. Rix +1 more
TL;DR: Simulation test results show that the virtual inertia and optimal allocation improves the system stability significantly, which in return gives additional incentive for RES integration.
Journal ArticleDOI
Walking on sunshine: Pairing electric vehicles with solar energy for sustainable informal public transport in Uganda
TL;DR: In this paper , the authors present a generic simulation environment to assess the grid impact and charging opportunities, given the unique paratransit mobility patterns, and assess the energy requirements of electric minibus taxis, which will have a knockon effect on the region's already fragile electrical grid.
