Micro Grid Operation to Interface of Distributed Generation

Abstract

Distributed generations (DG) are the ultra-modern mobile power resources which are located near the customer and generally used for small range of power requirements. The advantages of using embedded or local generation reserves are plenty which ensures power for all. The load along with local generation reserves and other auxillary units together is called microgrid. The energy management system involves in the proper balance with the parallel network which involves both local generation units along the traditional methods of power generation. The entire concept of local generation eliminates frequent conversion of AC to DC between source and load. The power from renewable reserves is utilized for local load requirements. The novel power electronic technology-based converters are designed and used for interfaced the non-conventional energy centers with the gird for effective and dynamic load management. In gird coupled operation, the hybrid AC/DC microgrid is presented in this paper and extensive analysis is carried out with respect to feasibility of the proposed system in real-time. The renewable sources are solar power module, wind energy conversion system and battery for storage purpose. The simulation platform is MATLAB/ SIMULINK environment and the results confirm the effectiveness of the proposed system.
