Beyond the Wires: Big Eddy-Knight Transmission Line

The United States needs to build more electric transmission lines at an unprecedented pace to connect and deliver clean, reliable and affordable energy. But for decades, developers relied on a “decide, announce, defend” approach that sidelined communities, fueled opposition and caused costly delays.

A new report from Environmental Defense Fund and Clean Air Task Force, Beyond the Wires: Community Benefits from Transmission Projects, shows that approach no longer works. By presenting five case studies covering six successfully constructed transmission lines in California, Massachusetts, Oregon, Utah, and Washington, the report highlights a clear trend: the most successful projects treat communities as …

Legal Frameworks for Long-Term Operation of Nuclear Power Reactors: Second Edition

With more than two-thirds of the world’s operating nuclear reactors over 30 years of age, countries around the world are assessing whether to allow reactor operation to continue past the 50-60-year mark and potentially up to 80 years. Ensuring a proper legal framework for the long-term operation (LTO) of nuclear power reactors is a key component of such considerations.

In the five years since the publication of the 2019 Legal Frameworks for Long-Term Operation of Nuclear Power Reactors (2019 LTO Report), numerous reactors have reached or exceeded the terms of their original operating licences and countries have further developed and …

Robust H-Infinity Control of a Two-Phase Interleaved Boost Converter for Second-Life Battery Integration in Battery Energy Storage Systems

Integrating second-life batteries (SLBs) into energy storage systems (ESSs) offers a sustainable and cost-effective solution for extending battery utility. However, the inherent uncertainties and performance variations of these aged batteries present significant challenges in maintaining system stability and efficiency. Hence, this work introduces a robust control strategy employing an H-infinity H∞ controller to regulate a two-phase interleaved boost (IBC) converter interfacing SLBs. The IBC topology effectively steps up the output voltage of SLBs while reducing current ripple and enhancing overall system performance. Also, the developed H∞ control, combined with the IBC, ensures resilience against system uncertainties and load variations, which …
