"Empowering Renewable Integration: Navigating Power System Health for Sustainable Transportation

The robustness of power systems plays a pivotal role in shaping the impact of renewables on global power grids and, by extension, the future of electric fast charging stations. Dr. (Eng.) KMSY Konara, a lecturer at Ruhuna University, recently addressed a prevalent perception that integrating renewables may pose challenges to the health of power systems. Speaking on November 20 as part of the Institution of Engineers Sri Lanka (IESL) Electrical, Electronic, and Telecommunication Engineering Section Committee Session 2023, Konara challenged the notion that integrating renewables is inherently problematic.

The concern often centers around the variability inherent in renewable sources like wind and solar, which can result in frequency fluctuations, voltage rise issues, and grid instability. Drawing on experiences in Norway, Konara shared insights from a project in Skarpnes, a solar village grappling with power quality and voltage rise challenges. The project's success hinged on the development of algorithms and decentralized strategies to manage power flow within distribution feeders effectively.

Konara emphasized the crucial role of a robust and healthy power system backbone, asserting that the world's transition to sustainable transportation, particularly with electric vehicles, necessitates a careful consideration of fast-charging infrastructure. He stressed the need for alignment between the deployment and operation of fast charging stations and the stability of the power grid. According to Konara, a dual approach involving a strong physical layer and a computational layer can effectively mitigate potential issues.

Drawing inspiration from European nations renowned for their high penetration of renewables, the discussion highlighted the success of comprehensive grid codes and customized computational models for each plant or charging station. Notably, Denmark, with its 6,000 megawatts of wind energy, showcased the feasibility of achieving high renewable penetration while maintaining a well-regulated and stable power grid through intricate grid codes enabling precise frequency control.

In essence, Konara's insights underscore the importance of proactive measures, innovative strategies, and a symbiotic relationship between power systems and renewable integration to pave the way for a sustainable and resilient energy future."

"Elevating Electric Fast Charging: Beyond the Physical Layer in Power Systems

The recent insights shared by industry specialist Dr. (Eng.) KMSY Konara shed light on a critical aspect often overlooked in the realm of electric fast charging stations — the role of a comprehensive computational layer. Konara emphasized the need to move beyond a singular focus on the physical layer of power systems, asserting that sustainable solutions for the challenges faced by electric fast charging stations require the integration of a robust computational layer.

In the pursuit of addressing issues associated with power system health, Konara remarked, 'For all the problems, we can't find the solutions within the physical layer alone. There should be a very comprehensive analytical layer or a computational layer on top of the physical layer.' This perspective underscores the interconnected nature of challenges in the power domain and the necessity for a multifaceted approach.

The significance of a healthy power system has become increasingly apparent as the global shift towards sustainable transportation gains momentum. Beyond being a technological necessity, a robust power grid emerges as a fundamental prerequisite for the widespread adoption of electric vehicles and the efficient operation of fast charging solutions. As the world accelerates towards sustainable modes of transportation, Konara's insights serve as a call to action, urging industry stakeholders to consider the holistic integration of physical and computational layers for a seamless and sustainable electric future."

"In conclusion, Dr. (Eng.) KMSY Konara's insights into the integration of a comprehensive computational layer alongside the physical layer in power systems offer a crucial perspective for the future of electric fast charging stations. As the world propels towards sustainable modes of transportation, Konara underscores the indispensable role of a robust power system. Beyond being a technological necessity, a healthy power grid becomes a fundamental prerequisite for the successful deployment and operation of electric fast charging infrastructure.

His emphasis on moving beyond singular solutions within the physical layer alone highlights the interconnected nature of challenges faced by the power sector. The call for a comprehensive analytical or computational layer on top of the physical layer signals the need for a holistic and multifaceted approach to ensure the seamless integration of electric vehicles and efficient fast charging solutions.

As the global community accelerates towards a sustainable and electric future, Konara's insights serve as a catalyst for industry stakeholders to prioritize the integration of both physical and computational layers. This approach is crucial not only for addressing existing challenges but also for laying the groundwork for a resilient and sustainable electric transportation landscape."
