As renewable energy generation grows globally, real-time asset management is crucial, particularly for offshore and remote systems. Electric grids are rapidly adopting renewable energy generation. Currently, there is no cost-effective condition monitoring method for real-time assessment of renewable energy sources, enabling intelligent asset management decisions to optimise utilisation and prevent unforeseen problems. Transformers are key assets that connect renewable generation plants to the grid. If one fails, generation can be lost for a lengthy time. The transformer in an on-grid system steps up or down voltage as needed. Transformer monitoring is crucial to Smart Grids. Transformer monitoring also allows demand analysis—what each family, business, or commercial institution consumes, where it consumes more, and when demand peaks. By its nature most renewable generation is intermittent, which places increased stress on transformers. To achieve an efficient, better and reliable generation of solar energy, it is necessary to monitor the transformers and solar generation system continuously. Hence in this work, real time health condition monitoring of devices in solar power transmission systems is presented. This system monitors the devices in real time with the help of IoT. Understanding transformer health and performance with real-time monitoring allows developing and optimizing proactive maintenance strategies for improving the performance of solar power transmission systems.

“…Three-phase full-bridge PFC is also a suitable option for bidirectional battery charging applications, in particular the three-level T-type converter, due to higher efficiency, although it has higher component number and higher complexity in control. Moreover, at high power levels, singlestage OBC converters would be preferred for bidirectional applications since they can achieve high power density and compactness, although they raise some challenges in terms of hardware design and achieving high efficiency [138]. Higher efficiency and better reliability could be achieved by an advanced control method and high-performance components.…”

A Review of Bidirectional On-Board Chargers for Electric Vehicles

et al. 2021

The fast development of electric vehicles (EVs) provides significant opportunities to further utilize clean energies in the automotive. On-board chargers (OBCs) are widely used in EVs because of their simple installation and low cost. Limited space in the vehicle and short charging time require an OBC to be power-dense and highly efficient. Moreover, the possibility for EVs to deliver power back to the grid has increased the interest in bidirectional power flow solutions in the automotive market. This paper presents a comprehensive overview and investigation on the state-of-the-art solutions of bidirectional OBCs. It reviews the current status, including architectures and configurations, smart operation modes, industry standards, major components, and commercially available products. A detailed overview of the promising topologies for bidirectional OBCs, including two-stage and single-stage structures, is provided. Future trends and challenges for topologies, wide bandgap technologies, thermal management, system integration, and wireless charging systems are also discussed in this paper.

EMI Filter Design for a Single-stage Bidirectional and Isolated AC–DC Matrix Converter

et al. 2018

View full text Add to dashboard Cite

This paper describes the design of an electromagnetic interference (EMI) filter for the high-frequency link matrix converter (HFLMC). The proposed method aims to systematize the design process for pre-compliance with CISPR 11 Class B standard in the frequency range 150 kHz to 30 MHz. This approach can be extended to other current source converters which allows time-savings during the project of the filter. Conducted emissions are estimated through extended simulation and take into account the effect of the measurement apparatus. Differential-mode (DM) and common-mode (CM) filtering stages are projected separately and then integrated in a synergistic way in a single PCB to reduce volume and weight. A prototype of the filter was constructed and tested in the laboratory. Experimental results with the characterization of the insertion losses following the CISPR 17 standard are provided. The attenuation capability of the filter was demonstrated in the final part of the paper.
