Integration and Distribution of Renewable Sources in DC Micro Grid With Energy Storage System

Ramji Tiwari, M. Anantha Kumar

This Paper presents a dynamic modelling of a DC Micro grid which has an Solar and Wind as an Distributed Energy Sources (DES).A Multi Port DC –DC converter is used to integrate the renewable sources to the DC bus. A Direct Driven Permanent Magnet Synchronous Generator is used with a variable speed control technique so that it can extract high wind energy below the rated speed of the wind. The both solar and wind changes according to the load requirement and also the availability. An Energy Storage Element such as Battery is also integrated with the DC bus so that it can store energy when present in excess.
