Because of the fundamental uncertainties inherent in microgrid design and operation, researchers have created battery and microgrid models of varying levels of complexity, depending upon the purpose for which the model will be used.
A dynamic model of islanded AC microgrids with battery energy storage system and static active as well as passive and dynamic induction motor loads. Time-domain simulations under MATLAB®/Simulink® environment. State-of-charge in the range of a safe charging status, that is, 20%<SoC≤80%.
Microgrids can be grid-tied, where the system is able to connect with a larger traditional grid, or standalone systems where there is no outside electrical connection. The Energy Systems Model and this paper focus only on standalone systems.
Section 3 presents a simple case study consisting in the robust optimization of a small microgrid with battery storage and aiming at characterizing the influence of the battery model in the design process. Section 4 gives the results associated with this case study and conclusions are presented in Section 5.
It is shown through simulation results and eigenvalue studies that the proposed models can exhibit a different performance, especially when the system is heavily loaded, highlighting the need for more accurate modeling under certain microgrid conditions.
