Control of Power Flow in Large-Scale PV Microgrid with Load Control and Energy Storage System

Today's traditional electricity grid was built to meet less overall demand, and used to distribute power to a very large number of users or consumers from a few central generators. It can support electricity output, transmission, distribution, and control operations, In short one way communication. Micro-grid, however, is a modernized grid that allows bidirectional power and data flow using two-way communication and control technologies, leading to a whole new functionalities and applications. Furthermore, it has the potential to integrate distribution generators to form a small-scale grid called a microgrid, including renewable energy. Microgrids operate in "Grid connected mode" with the main grid, or in "Island mode" independent of utility grid or main grid. The first chapter gives introduction to Micro-grid and explains it, as well takes about inspiration its necessity and other topics. The second chapter is dedicated to the description of Micro-grid simulated in this dissertation. Distribution generators are discussed with their impact while connecting it to the Micro-grid in the third. Requirements for while connecting the distributed generators to the Micro-grid are also discussed in the third chapter. This project simulate the Micro-grid in SIMULINK, MATLAB Ra2015 and explains the key components of it in forth chapter. The last section consists of Appendix A which includes calculation of the project, conclusion, recommendation and references.
