Modelling and Simulation of Isolated DC Microgrids Supplied by Renewable Energy Resources
This paper presents a detailed development of models of typical components that form a hybrid power system. Hybrid system consists of a small wind turbine, a photovoltaic string, a battery string and a load. The battery string is the most important element of the system, being the only component able to process a two way power flow. It is connected directly to the DC bus bar, as well as the load supplied, and its function is double ; securing uninterruptible power supply and maintaining system voltage in set boundaries. The battery’s voltage is a nonlinear function depending on its state of charge, current and environmental conditions. Accurate state of batteries voltage is critical for modelling production of all other components in the hybrid system, since their production is directly depended on this value. All of the modelled components are connected to a direct current (DC) busbar. Presented model is based on real measurement results and creates an environment for simulation of electrical supply in isolated microgrids.
