Abstract |
|
Now day’s microgrid is popular because it can be handle the impacts of Distributed Generators (DGs) and make conventional grids suitable for large scale arrangements of distributed generation. However, the introduction of microgrids brings some challenges. Protection of a microgrid is one of them. Due to the existence of generators at all levels of the distribution system and two operating modes, i.e. Grid Connected and stand-alone modes, the fault currents in a system vary substantially. Consequently, the traditional fixed current relay protection schemes need to be improved. This paper presents a conceptual design of a microgrid protection system which utilizes extensive communication to monitor the microgrid and update relay fault currents according to the variations in the system. This paper also have MATLAB simulation as well as results are presented for both the modes. |
