User Manual for DALINE 1.1.5: DALINE: A Data-Driven Power Flow Linearization Toolbox for Power Systems Research and Education

Abstract

Power flow linearization is a fundamental technique in power system operations, crucial for both academic research and industry applications. Despite its importance, many advanced linearization methods, particularly those driven by data, remain largely inaccessible, neither open-sourced nor integrated into widely used software platforms. To address this gap, we introduce Daline, an open-source MATLAB toolbox specifically designed for the power systems community. Daline provides a comprehensive suite of 57 linearization methods, including 53 data-driven techniques and 4 physics-driven approaches. Daline's robust capabilities cover a spectrum of functionalities: (1) Data Generation, (2) Data Pollution, (3) Data Cleaning, (4) Data Normalization, (5) Method Selection, (6) Method Customization, (7) Model Linearization, (8) Model Evaluation, and (9) Result Visualization. These functionalities enable users to execute complex tasks with minimal coding effort. This manual serves as an in-depth guide, providing a gentle introduction for new users and a detailed reference for advanced users, explaining Daline's features, functions, parameters, syntax, and practical applications, and all the other related contents. Our vision is to empower users by saving their valuable time and fostering innovation in power systems analysis through accessible, state-of-the-art linearization tools.
