Summary
In Argentina, the growing deployment of inverter-based renewable generation is progressively displacing conventional synchronous generation, which introduces significant challenges to the stability and reliability of the electrical system. One effect is the reduction of system damping due to the lower number of synchronous generators in service, since these provide intrinsic inertia and allow the use of Power System Stabilizers (PSS), contributing to the damping of low-frequency electromechanical oscillations, known as inter-area oscillations.

Oscillation Dampers (POD) into Battery Energy Storage Systems (BESS). The methodology consists of detailed digital simulations of the Argentine Electrical System, considering 2028 as the baseline scenario, and adding the planned renewable energy to be installed. Based on this case, scenarios with BESS-POD equipment activated and deployed in the system are evaluated, considering government initiatives for BESS installation.
The results show a significant increase in the damping of inter-area oscillations when the BESSPOD equipment is activated, with a reduction in the amplitude and settling time of the oscillations, contributing to the overall stability of the system.
A solid technical basis is provided for planners and regulatory authorities to adopt this technology as a key service for large-scale renewable energy integration, while ensuring grid reliability.
