Coordinated Battery Electric Vehicle Charging Scheduling across Multiple Charging Stations

Saman Mehrnia, Hui Song, Nameer Al Khafaf, Mahdi Jalili et autres

The uptake of battery electric vehicles (BEVs) is increasing to reduce greenhouse gas emissions in the transport sector. The rapid adoption of BEVs depends significantly on the coordinated charging/discharging infrastructure. Without it, uncontrolled and erratic charging patterns could lead to increased power …

Electric vehicle charging technologies: topologies, modulation and control

Inam Ullah Nutkani, C. A. Teixeira, Richardt Howard Wilkinson, Nil Patel et autres

Electric vehicle (EV) chargers are the primary systems that enable the exchange of energy between the vehicle battery and the AC electricity grid. Charging systems are based on power electronic converter platforms that are operated using sophisticated control strategies that enable specific …

Floquet Stability Analysis of Alternative Synchronization Strategies for Parallel Grid-following Distributed Generators

Rahul Agrawal, Brendan Peter McGrath, C. A. Teixeira, Richardt Howard Wilkinson et autres

Nano-grids enable the integration of distributed generators (DGs) in small-scale contexts such as residential households. Such DGs typically utilize current regulators with a phase-locked-loop (PLL) to enable grid-following behavior, where synchronization can be achieved using two alternative strategies: direct-synchronization based on grid …

A short term multistep forecasting model for photovoltaic generation using deep learning model

Lakshmi Palaparambil Dinesh, Nameer Al Khafaf, Brendan Peter McGrath

Developed countries have substantial investments in renewable energy currently, particularly Photovoltaics (PV), for achieving net-zero emissions. But PV generation is highly volatile and hence achieving supply-demand balance is challenging. Robust forecasting models will help PV integration and penetration into the grid, making …

Analytical Determination of Harmonic Controller Gains for High Performance Grid-Connected Resonant Current Regulators

Donald Grahame Holmes, Brendan Peter McGrath

While a variety of strategies have been proposed to calculate the gain parameters of cascaded Proportional Resonant (PR) and Vector Proportional Integral (VPI) grid-tied current regulators, typically the presented approaches rely either on heuristic gain/stability considerations, or on simplistic interpretations of the …

Artificial Neural Network for Disaggregation of Behind-the-Meter Energy Consumption and Generation

Nameer Al Khafaf, Brendan Peter McGrath, S. M. Nawazish Ali, Mahdi Jalili

Electricity smart meters have been widely adopted primarily for billing purposes. These meters provide a net-metering of the residential unit without distinguishing between the energy consumption or generation. As the penetration of distributed solar photovoltaic is expected to account for at least …

A Sensorless Grid Voltage Estimation Scheme for Initial Synchronisation of Single-phase Renewable-based Distributed Generators

Asma Ahmad Mirza, Inam Ullah Nutkani, C. A. Teixeira, Brendan Peter McGrath

Numerous research studies have explored voltage-sensorless strategies to minimise detrimental transient inrush currents during the initial synchronisation of distributed generators (DGs). Most of these approaches require that the DG’s voltage source inverter (VSI) briefly operates in rectification mode, demanding a DC-link energy …
