Micro Grid: An Energy Efficient Approach for Modern Power System

Renewable Energy Generation is a fast growing field of study under Power System Engineering. Renewable Energy has gained much popularity due to the fact that it can be easily setup near load centres and have very low running cost. Renewable Energy Generation also has the added advantage that it is environment friendly and will help in sustained development. This paper intends to study the interaction of multiple renewable sources when it is operated together to supply AC as well as DC Loads. This paper studies the behaviour of micro-grid in grid connected mode of operation. Bi-Directional operation of converter is also studies using decoupled vector control. Centralized Micro-Grid Controller is used for the Energy Management of the test system. Solar and Wind are the two renewable energy sources selected for study in this paper. Battery is also used in this system for energy storage. AC as well as DC loads are connected to the system to study the flow of energy.
