Electric Vehicles Charging Time Constrained Deliverable Provision of Secondary Frequency Regulation

IEEE Transactions on Smart Grid

The paper proposes a strategy for using aggregated electric vehicles (EVs) to provide secondary frequency regulation (SFR) in renewable energy systems while respecting EV charging time constraints. It demonstrates that this approach can improve system performance with minimal cost increase, validated through simulations on the IEEE 39-bus system.

Virtual Inertia Scheduling (VIS) for Real-time Economic Dispatch of IBRs-penetrated Power Systems

IEEE Transactions on Sustainable Energy

The paper introduces virtual inertia scheduling (VIS) to manage the increasing penetration of inverter-based resources (IBRs) in power systems. VIS optimizes inertia scheduling and generation dispatch for secure and cost-effective support, validated through simulations on a two-machine system and a modified IEEE 39-bus system.

Disturbance Propagation in Power Grids With High Converter Penetration

Proceedings of the IEEE

The article explores how high penetration of converter-interfaced renewable energy resources affects disturbance propagation in power systems. It shows that increased converter penetration speeds up disturbance propagation due to reduced system inertia, but fast active power control of converters can mitigate this effect, as demonstrated through simulations on various power system models.

Electricity consumption variation versus economic structure during COVID-19 on Metropolitan Statistical Areas in the US

Nature Communications

The paper estimates changes in electricity consumption (EC) at the metropolitan level across the continental U.S. during the initial two months of the COVID-19 pandemic, showing a reduction in total EC linked to industry shares and an increase in residential EC regardless of incidence level or economic structure. These findings can guide responses to future socio-economic crises.
