Analysis of different symmetrical and asymmetrical fault on SPV-wind based hybrid microgrid.

In this paper, the effect of various symmetrical and asymmetrical fault on a hybrid micro-grid system, consisting of a solar photovoltaic array and fuel cell, is analyzed. With the advancement in technology, there has been an immense increase in the demand for electrical energy that has not only become a challenge for its production but also for its distribution. This rising demand is complicating the power grid by necessitating greater reliability, efficiency, and security, as well as environmental and energy sustainability. Mitigating of faults, an unavoidable part of grid, in the quickest possible time is also necessary for the supply of steady power to consumers. The impact of the fault current on the inverter-connected DGs as well as conventional DGs is also analyzed. A MATLAB Simulink model of hybrid Micro-grid is developed and different characteristics is analyzed and appropriate protection schemes are deployed. In this paper the presence of both DC and AC sources in the modelled network brings out the possibility of DC and AC analysis together which is a crucial part of the power system.
