摘要

Studies related to the integration of distributed energy resources (DERs) face challenges in considering models for the primary energy source, the conversion equipment, the inverters, and the microgrid. Most of the current approaches only consider some of these models, then the complete modelling is uncommon, leading to simplified system representations. As a solution, this paper presents a three-stage approach to easily integrate the generation and storage system models into the dq0 control algorithm of a voltage source converter (VSC), useful in microgrid studies. The considered DERs, correspond to battery energy storage system (BESS), wind generation and photovoltaic (PV) generation systems; then, the model influence and the variation of the primary energy source modify the control references. This approach allows an appropriate balance between model accuracy and simplicity of steady-state and dynamic equivalent models for converter integrated DER (CIDER). The results show how this modelling facilitates the steady and dynamic state studies, as is evidenced in the tests performed in a CIGRE based microgrid.
