Abstract
One of the main goals of smart grid is to create a decentralized and consumer controlled power system which can increase efficiency, reliability and reduce cost for energy. One of the ways to achieve this goal is to introduce Distributed Energy Resources (DER) into the smart grid. DER devices are small scale power generation units which can provide energy according to the consumer demand. DER systems are interconnected with many other systems in the smart grid. The major systems interconnected with DER system are micro grids, distribution system and synchrophasor system. This project discusses security issues, counter measures, and research issues in DER and systems interconnected with it. It covers proper data handling practices for maintaining confidentiality, integrity, availability, and accountability. In conclusion, this project helps to evaluate security and possible best practices for energy efficient solutions associated with systems interconnected with DER.
