Sub-synchronous oscillations are becoming commonplace in weak areas of power systems with high levels of renewable generation, affecting their operation. Moreover, there is a lack of methods and techniq.
In this manuscript, the combination of static and dynamic techniques is utilized and consolidated to derive general conclusions when mitigating sub-synchronous oscillations by means of grid-forming battery energy storage systems (GFM BESSs).
An equivalent model of a grid-forming energy storage system with a large-scale battery storage system operating in standalone mode has been developed, as shown in Fig. 1. The system consists of two main components: the start-up power source and the power to be started.
In standalone grid-forming energy storage systems, self-excited oscillations, triggered by the interaction between the storage PCS controllers and the nonlinear characteristics of the transformer, were observed. This paper presents the following conclusions. 1. Oscillations arise from poor voltage stability.
Self-excited oscillations frequently occur in power systems [1, 2, 3], especially with the growing presence of renewable energy in standalone networks. Understanding the mechanisms and developing suppression strategies for such oscillations is crucial.
Voltage/power system oscillations in the grid are observed under different operational conditions and faults. For instance, 17-Hz power system oscillations with a maximum peak-to-peak magnitude of 1.57%, as the ones previously presented, appear when the output of the wind farm is above 130 MW.
However, research on the sub/super-synchronous oscillations in standalone networks is still limited. These oscillations are often triggered by interactions between renewable energy plants and weak grids [4, 21, 22].

The government of Portugal has announced plans to invest €400 million (US$466 million) to improve its grid management capabilities and increase its battery energy storage system (BESS) capacity.
The Portuguese Ministry of Energy has allocated €99.75 million ($107.6 million) for grid flexibility and energy storage projects which should be installed by the end of 2025. From ESS News Portugal is seeking to promote flexibility and balance its power system with energy storage as it continues to break records for solar energy production.
REUTERS/Pedro Nunes/File Photo Purchase Licensing Rights LISBON, July 28 (Reuters) - The Portuguese government plans to invest up to 400 million euros ($466 million) to improve grid management and boost battery storage following a massive blackout across Spain and Portugal in April.
From ESS News Portugal is seeking to promote flexibility and balance its power system with energy storage as it continues to break records for solar energy production. To this end, the country's Ministry of Energy announced on Wednesday that it has allocated €99.75 million ($107.6 million) in a bid to support 500 MW of energy storage projects.
Portugal has only about 13 megawatts of battery storage capacity, and the goal is to reach 750 megawatts, although no timetable has been set yet. According to the latest daily data from REN, electricity consumption in Portugal stood at 115 GWh on June 20. ($1 = 0.8581 euros)
Europe is expected to deploy over 90 GWh of utility-scale battery energy storage projects by 2030, and we are well positioned to support this demand along with the wider EMEA region's rapid energy storage growth,” said Powin CEO, Jeff Waters.
A surge in voltage triggered a cascade of power plant disconnections, leading to the outage that spread to Portugal, which was importing electricity at the time.
