Most of the solar photovoltaic (SPV) installations are connected to distribution networks. The majority of these systems are represented by single-phase rooftop SPVs connected to residential low voltage (LV) grids. The large SPV shares lead to grid integration issues such as voltage rise, overloading of the network components, voltage phase unbalance etc. A rapid expansion of Electric Vehicles (EVs)...
Electrical distributors in Australia are experiencing high penetration levels of small scale distributed generation, such as solar photovoltaic systems, particularly being installed on houses that are connected to the Low Voltage network. Distributed generation is challenging the traditional operating paradigm and can result in occurrences of voltage rising to the point where it goes above safe limits,...
Installation of single-phase rooftop photovoltaic (PV) systems in low voltage (LV) residential feeders without controlling their ratings and locations may deteriorate the overall grid performance including reversed power flows, high losses and unacceptable voltage profiles. Therefore, in recent years the utilities have adopted limitations on the maximum allowable number of PVs in LV networks. To overcome...
The current on the low voltage side of the high frequency transformer of a dual active bridge converter is subject to rapid rising and falling edge; in designing the converter, the peak current is a key factor to achieve robustness and reliability. To limit the peak current, the adoption of a further inductor in series with the transformer is a feasible solution. In this paper the authors propose...
