Impulsive Noise Mitigations in Powerline communications

Abstract: Powerline communications (PLC) is vital for leveraging existing electrical infrastructure, offering cost-effective and reliable connectivity. By utilizing established power lines, PLC eliminates the need for additional cabling, making it particularly advantageous in areas where deploying new infrastructure is impractical or expensive. This accessibility extends connectivity to remote regions or places with poor wireless coverage. Moreover, PLC ensures reliability, as power lines are typically well-maintained and less susceptible to interference compared to wireless signals. Its interoperability enables seamless integration with existing networks, supporting various applications such as smart grid management, home automation, and industrial control systems. Advancements in PLC technology have led to significant improvements in data transmission speeds, enabling high-speed internet access and multimedia streaming.

The PLC channels typically suffer several factors that limit its performance, which includes, fading due reflections through multiple routes and impulsive noise due to interference that travels along the power lines, often caused by fluctuations in voltage, switching operations of electrical devices, or harmonics generated by nonlinear loads like electronic equipment. Both fading and impulsive noise can degrade the quality of PLC signals and reduce the effectiveness of data transmission. To mitigate these issues, various techniques such as signal filtering, error correction algorithms, and frequency hopping spread spectrum (FHSS) modulation are employed in PLC systems to suppress noise and improve communication reliability. This tutorial aims at describing the basics of PLC systems, discuss the main channel models, and present state of the art impulsive noise mitigation schemes.

Design and Control of Electric Vehicle (EV) Chargers and their Impacts on Power Distribution Network

Abstract: Electric vehicles (EVs) are gaining traction worldwide as a sustainable alternative to conventional internal combustion engine vehicles. However, the widespread adoption of EVs poses significant challenges to the utility grid, particularly in terms of load management, peak demand, and grid stability. The vehicle-to-grid (V2G) functionality is used to supply various services like regulation of active power demand, reactive power compensation, shaving peaks and filling valleys in load demand, frequency and voltage regulation, compensation of harmonics in grid current, improvement in system reliability, stability, and efficiency. This tutorial will provide a comprehensive overview of EV charger design and control techniques to ensure grid-to-vehicle (G2V) and V2G modes of operation. Further, the integration of EV chargers into the existing grid may lead to drop in voltage profile of various buses which deteriorate the hosting capacity of the existing power system network to accommodate EVs. In this tutorial, the various techniques which are used to assess the hosting capacity of the power system network will be discussed. This tutorial aims to delve into the intricacies of designing and controlling Electric Vehicle (EV) chargers, focusing on their profound impact on the utility grid. With the rapid proliferation of electric vehicles, the efficient integration of charging infrastructure into the existing distribution network is paramount. This tutorial will explore various aspects including charger design, smart charging strategies, integration challenges, and solutions to ensure a harmonious relationship between EV charging and the distribution network. Complete design guidelines for EV charger will be elaborated. Different control methodologies and controller design will be illustrated. Simulation and experimental results will be shared. A case study of Kahramaa power distribution network will be discussed to understand the major impact of EV charger integration.
