Senior design project
Design of a Test-Bed for Real Time Testing and Validation of Smart Grid Devices and Algorithms at QU
After getting the testbed ready to work the design of advanced applications that will validate the testbed and serve the SGDRIL is necessary.
Microgrid Energy Management System
An EMS for the microgrid will be modelled in the RTDS as the first advanced application. The microgrid that is considered consists of renewable energy sources, battery storage system, diesel generators, controllable loads. This combination will offer a variety of scenarios that could be used for experimenting, testing and validating EMSs for microgrids. The microgrid modelling will be constructed as separate subsystems first, each subsystem is consisting of a distribution energy resource (DER) and the final step will be combining the subsystems together and then implement the designed EMS in an external controller.
Digital Relay
Smart grid has introduced many distributed energy sources such as PV panels which allows bidirectional power flow. Thus, bidirectional short circuits may accurse, islanding and many other issues regarding power quality. Under these circumstances, remotely controlled protection system that is usually derived using a distribution management system or SCADA, is used. One of the main protection devises that use to maintain safe power system is protective relay. There are many types of relays that are normally used such as overcurrent (directional and unidirectional), distance and deferential relays. Digital relays nowadays are used because they offer economic and feasible alternative moreover they are used in research areas.
