Abstract

As the number and diversity of Distributed Generation (DG) on the grid increases, dispatching these resources at the right time and accounting correctly for the flow of energy become complex problems that require reliable monitoring. There is urgent need for methods of efficient and reliable monitoring and control for such sources, Traditional Supervisory Control and Data Acquisition (SCADA) systems with centralized control rooms, dedicated communication lines, and specialized operators, are not cost effective to handle a large number of DG resources spread over the grid. The Internet provides a convenient point-to-point communication network that replaces dedicated telephone lines. Inexpensive computers equipped with suitable communication and control software manage the distributed resources. A clever new monitoring system to ensure a proper interface between the DGs and the electric utility system will be essential for DG. Such monitoring could need to communicate with the utility to provide the DGs information. Most importantly, they must be fast and reliable to ensure the system runs safely, In that research, the authors proposed a monitoring system which could collect all needed data of DG. This system is based on the concept of redundant communication and redundant display of all information of DGs locally or remotely. The proposed system is designed using GSM as wireless communication and an internet over telephone line as a wired communication to create redundant communication.
