Impact of battery energy storage systems on the dynamic behavior of low-inertia power grids

Yihui Zuo

The extensive deployment of non-synchronous generation determines lower level of grid inertia resulting in deteriorated frequency containment performance and abnormal frequency excursions in case of contingency. This calls for identifying assets, controls, ...

Performance assessment of grid-forming and grid-following converter-interfaced battery energy storage systems on frequency regulation in low-inertia power grids

Mario Paolone, Sidi-Rachid Cherkaoui, Fabrizio Sossan, Yihui Zuo, Antonio Zecchino, Zhao Yuan

Power systems with large shares of converter-interfaced renewables may be characterised by low grid inertia due to the lack of frequency containment provided by synchronous generators. Battery energy storage systems (BESSs), which can adjust their power ou ...

Balancing management of strategic aggregators using non-cooperative game theory

Sidi-Rachid Cherkaoui, Mokhtar Bozorg

The aggregators are intermediary players at the distribution system level. They manage the financial transactions of resources such as micro-turbines (MTs), photo-voltaic (PV) production systems, flexible demands (FDs), and must-run demands (MDs) in the en ...

Inertia location and slow network modes determine disturbance propagation in large-scale power grids

Philippe René Joseph Jacquod, Laurent Vincent Pagnier

Conventional generators in power grids are steadily substituted with new renewable sources of electric power. The latter are connected to the grid via inverters and as such have little, if any rotational inertia. The resulting reduction of total inertia ra ...
