Abstract

"A micro-grid is a strong interconnection of distribution energy resources close to the loads. Though these micro-grids can solve many problems that beset the present-day grid, indiscriminate application can cause serious problems. A thorough study is needed to identify the potential problems and to develop effective techniques to mitigate them.

Micro-grids can operate with the main grid system to support the grid voltage or as an isolated system to support customers isolated from the grid. In islanding operations, the micro-grid can continue to supply power to the customers thereby increasing the reliability of the power system. During operations connected to the grid, the micro-grid can supply power to the grid. This thesis investigates the micro-grid operations both when connected to the grid and during islanding of the system. In a micro-grid with wind turbines, when the main grid is disconnected, a reactive power source would be needed to keep the wind power generation. Also the load change scenario has been simulated to investigate the problems that would arise when there is a change in the load requirements. In addition to the above, the use of Static Synchronous Compensator (STATCOM) for the purpose of stabilizing the micro-grid voltage during short circuit faults is also simulated"--Abstract, page iii.
