 The increasing penetration of inverter-based resources (IBRs), e.g, renewable and energy storage systems, is fundamentally reshaping power grid dynamics. Unlike conventional resources, IBRs interact with the grid through power electronics operating at microsecond timescales, introducing ultrafast dynamic phenomena that conventional time-domain simulation methods, e.g., RMS techniques, fail to capture [1]. Electromagnetic transient (EMT) simulations can capture these fast dynamics but require integration time steps of 1–50 microseconds, making system-wide studies computationally intractable. This creates a critical bottleneck for stability analysis, contingency planning, and control design in modern power systems, as time-domain simulation has been a fundamental tool for analyzing system stability and dynamic performance [2]. Recent grid incidents, such as the April 2025 massive blackout in Spain and Portugal, underscore these limitations and the need for scalable analysis tools. Overcoming this computational barrier is crucial to the stable integration of renewable energy sources as mandated by climate change mitigation policies [3].

 Reuse of this dataset is most naturally suited to researchers working at the intersection of power systems and machine learning for surrogate modeling, using approaches such as neural operators and physics-informed learning, with power systems as the sole application domain. Researchers outside the power systems field may find the paired coarse/fine-resolution structure valuable as a benchmark for resolution-invariant time-domain simulation of physical systems. However, users should be aware that the system studied, a single inverter infinite bus (SIIB), is a canonical but simplified test case. Conclusions drawn from models trained on this dataset may not directly generalize to large-scale multi-machine or multi-inverter systems without further validation. The reuse of the dataset is unlikely to be impacted by changes in the social, political, or historical context. That said, this dataset supports research relevant to energy transition. Hence, the popularity of use may vary across space and time, as the social and political support for energy transition mandates changes. 
 
+The synthetic dataset creation plan was driven by three requirements derived from this formulation:
+
+- Paired resolution: To study time step-invariance, the dataset must contain trajectories of the same scenarios simulated at fundamentally different resolutions. EMT simulation in PSCAD captures fast switching and electromagnetic dynamics at microsecond resolution; RMS simulation in MATLAB Simulink operates at millisecond resolution capturing electromechanical dynamics. Pairing these for identical scenarios enables direct study of cross-domain generalization.
+- Control mode coverage: Both GFM and GFL inverter control modes are included because they represent qualitatively different dynamic behaviors; GFM converters regulate voltage and frequency autonomously while GFL converters synchronize to an existing grid [5], and surrogate models must be evaluated across both.
+- Scenario diversity: To support generalizable learning, 4,000 distinct operational scenarios were generated by stochastically sampling load parameters, active and reactive power references, and disturbance types, i.e., load changes, faults, voltage variations, spanning both stable and unstable system responses.
+
+The choice of the SIIB as the test system was deliberate: it is the canonical reduced-order representation of an IBR connected to a stiff grid, sufficiently rich to exhibit practical stability phenomena while simple enough to generate large simulation datasets at tractable computational cost. That said, all data are generated from simulation models rather than real-world measurements, so results depend on model fidelity and parameter assumptions. A few intrinsic biases are worth noting. First, the choice of disturbances, parameter ranges, and operating conditions defines the distribution of system behaviors represented in the dataset, which may not fully cover all real-world scenarios. Second, the binary oscillatory/non-oscillatory label captures one specific behavioral distinction. It does not encode richer stability classifications such as voltage collapse, frequency instability, or loss of synchronization [1]. Users framing downstream tasks around those phenomena should treat the labels with caution. Despite these limitations, the dataset is intentionally designed to provide a controlled, diverse, and physically grounded benchmark for developing and evaluating ML methods for power system time domain simulation.

+
+This dataset contains no data about human subjects. All data is generated entirely from physics-based simulation environments, i.e., PSCAD and MATLAB Simulink, under controlled, synthetic operational scenarios. Accordingly, informed consent is not applicable.
+
+The primary benefit of this dataset is the acceleration of research on computationally tractable power systems simulation and analysis tools. The inability to efficiently simulate IBR-dominated grids at high resolution is a practical barrier to the stable integration of renewable energy resources. Datasets that enable surrogate modeling research support the development of tools that grid operators, planners, and researchers need to manage the energy transition safely. The dataset is made publicly available without restriction to maximize this benefit to the research community. The potential harms of releasing this dataset are minimal. The SIIB test system is a canonical academic test case with no direct correspondence to any real grid infrastructure. No proprietary control parameters, real network topology, or operational data from any utility or grid operator is included. The dataset does not contain information that could be used to identify vulnerabilities in real infrastructure, facilitate cyberattacks, or compromise grid security. Furthermore, the dataset explicitly focuses on a simplified system (SIIB), and this limitation is documented to discourage inappropriate use in more complex settings.
+
+An alternative approach to constructing this dataset would have been to collect real operational measurement data from grid-connected inverters using, e.g., synchro-waveform recordings [6]. This approach was not pursued for two main reasons. First, real-world data is unnecessary for the scope of the dataset and is nearly impossible to obtain, such that it satisfies the paired EMT and RMS representation of the system, as well as the diversity of operational scenarios. Inverter control parameters are typically proprietary to manufacturers and are not disclosed, making it impossible to construct the well-characterized scenarios that surrogate model training requires. Moreover, and critically for the intended ML application, real-world grid operation rarely produces trajectories that are unstable or near the stability boundary. Second, even if such well-characterized data can be obtained from real-world systems, it would be subject to data sharing agreements, confidentiality obligations, and regulatory constraints that would prevent open public release, limiting the dataset's utility to the broader research community. The synthetic simulation approach was therefore chosen for its scientific advantages, i.e., full control over scenario parameters, ground truth availability, and the ability to generate paired EMT/RMS trajectories, as well as accessibility benefits.
+
+Overall, the benefits of enabling research in scalable and accurate power system simulation are considered to outweigh the potential risks, provided that users are aware of the dataset’s scope and limitations and apply appropriate validation when extending results to real-world systems.
