ComEd Grid Labs-Why the Power Sector Needs Advanced Labs
The severity and frequency of severe weather events has risen in recent years due to climate change, while cyber-attacks have also become more of a threat as technological advances threaten to outpace cyber security. Stakeholders have recognized the imperative nature of supplying sustainable, resilient power to every community. The power industry, and particularly advanced utilities have been working tirelessly to ensure the resiliency of the power grid, and to lead the transformation into grid of the future. Labs play a particularly important role in this transformation as will enable an accurate and expedited system modeling and analysis. The paper discusses ComEd’s efforts, as the largest electric utility in the state of Illinois serving more than 4 million customers, to build and leverage advanced labs in designing the grid of the future.

Utility-Scale Shared Energy Storage: Business Models for Utility-Scale Shared Energy Storage Systems and Customer Participation
Due to climate change, supply scarcity, and society’s desire to expand access to electricity and improve energy-system resilience, there has been an increasing demand to invest in and use renewable energy sources (RESs) that are environmentally friendly, efficient, sustainable, and affordable. This has diversified and decentralized energy sources and increased their penetration.

Islanding Detection of Grid-Forming Inverters: Mechanism, Methods, and Challenges
Over the past decades, because of boosted energy demands and the serious concerns of climate change, inverter-based resources (IBRs) have been widely deployed to integrate renewable energy into power systems for the goal of carbon neutrality. Thanks to the full controllability of power electronic devices, IBRs have the capability to implement reliable and flexible power regulation, which makes them technically feasible for enhancing the resilience and energy efficiency of power systems.

Flexibility in Sustainable Electricity Systems: Multivector and Multisector Nexus Perspectives
As environmental concerns increase, researchers, policy makers, and the public in general are becoming more interested in options to make energy more sustainable while at the same time ensuring that energy systems are affordable, reliable, and resilient. This dynamic is bringing about challenges across the world, as established energy systems (such as those in cities) must be enhanced to integrate large volumes of renewable energy sources (RES), while new or evolving systems (for instance, in developing economies) must be planned to manage the increasingly extreme conditions associated with climate change.

The Green Impact: How Renewable Sources Are Changing EU Electricity Prices
The European Union (EU) energy policy focuses on achieving a balance between three main pillars: increase the security of supply, reduce the impact of climate change, and improve economic competitiveness. To accomplish these objectives, the EU has been creating competitive conditions that internalize environmental externalities, and it has also actively promoted renewable energy.

Performance Degradation of Levee-Protected Electric Power Network Due to Flooding in a Changing Climate
This paper presents a methodological framework to evaluate the resilience, with the primary focus on performance degradation, of levee-protected electric power networks to flooding in a changing climate. To this end, a multi-disciplinary framework is established by integrating climate science, hydrology, and electric power network analysis. The framework quantifies the effect of climate change on flood hazard levels in a levee-protected area and the subsequent changes in the resilience of the electric power network.

Green Gas to Replace SF6 in Electrical Grids
Environmental considerations are increasingly taking a front seat in all arenas of our daily lives—political, industrial and societal. Not least among the major concerns are global warming and the greenhouse gases that contribute to it, as their concentration in the air reaches new heights. Hence the power industry’s focus on sulfur hexafluoride (SF6) and the need to find a suitable alternative for it in industrial applications. Grid Solutions, a GE and Alstom joint venture, has identified a fluoronitrile based gas mixture dubbed ‘g3–green gas for grid’ that is such a alternative.
