Analysis of Micro-grid power supply reliability

Micro-grid is the technique which could access the utility grid with combined renewable energy generation resources, loads, energy storage devices and control devices. It is generally agreed that, Micro-grid could reduce or avoid the impact of wide range failure to the users and improves the power supply reliability. This paper proposed a Monte Carlo method to evaluate the reliability of Micro-grid. A Micro-grid example which includes energy storage devices, distributed wind turbines, solar arrays and time-varying loads is built in this paper and the corresponding reliability indices are calculated.
