Modelling of energy sources and energy storage devices for the purpose of analysis the low voltage microgrid operation
Main Article Content
Abstract
The paper presents methods of modelling electricity sources and storages for the purpose of analysing the performance of microgrids in steady and transient states. The subject of the study is a low voltage microgrid comprising controllable and uncontrollable energy sources, storages and loads. Models of energy sources and storage are presented as well as their control algorithms for the two modes of operation of the microgrid: in connection with the utility network, and in autonomous operation. A simulation model of the microgrid was developed in PSCAD/ EMTDC. Selected simulation results are presented which illustrate the performance of the system under assumed conditions.
