Core Concepts
This report provides a detailed description of a synthetic 33-bus microgrid, including its structure, dynamic models, and time-series parameters of loads and generations. The microgrid incorporates converter-interfaced renewable energy resources and energy storage systems, and the time-series parameters are generated based on open-source ARPA-E PERFORM datasets.
Abstract
The report presents a synthetic 33-bus microgrid (MG) with the following key features:
Network Structure:
The MG is adapted from the IEEE 33-bus distribution network.
It contains 23 loads and 9 converter-interfaced generations, including 3 wind generators, 2 solar panel generators, and 4 energy storage systems.
Dynamic Model:
The dynamics of the converters are formulated with hierarchical control and renewable uncertainties.
The load and network models are also included, leading to a complete dynamic model of the MG in a differential-algebraic equation (DAE) form.
The DAE model is then transformed into an ordinary differential equation (ODE) model in an affine form with respect to the renewable uncertainty and control.
Time-Varying Parameters:
The time-invariant parameters of the components and controllers are provided.
The time-varying parameters, including load power, actual and forecast power outputs of generators, and setpoints of converters, are generated based on the ARPA-E PERFORM datasets.
The one-year profiles of these time-varying parameters are presented, with a focus on the one-week profiles.
The detailed description of the synthetic 33-bus MG, including its structure, dynamic models, and time-series parameters, provides a comprehensive reference for researchers and engineers working on microgrid modeling, simulation, and control.
