Основные понятия
Development of an open-source simulation toolbox, PowerSimulationsDynamics.jl, to study power systems with high penetrations of Inverter-Based Resources.
Аннотация
The article introduces PowerSimulationsDynamics.jl, implemented in Julia, focusing on modeling power systems with Inverter-Based Resources (IBRs). It discusses the limitations of current commercial tools and the need for a modular and open simulation platform. The software design includes system models, Jacobian auto-differentiation, injection device modeling, load models, network circuit modeling, initialization procedures, perturbations handling, and small signal stability analysis. Case studies validate the tool's performance against commercial simulators.
Simulations are crucial for studying power system dynamics due to their complexity.
New energy technologies like IBRs require advanced simulation tools.
Open-source platforms like PowerSimulationsDynamics.jl offer flexibility and customization.
The software design includes various components like injection devices, load models, and network circuits.
Small signal stability analysis is essential for assessing system behavior under perturbations.
