Development of Microgrid Testbed for Real Desert Environment Testing and Evaluation: Project Experience

This paper presents the microgrid testbed that is constructed for a real desert environment testing and evaluation. The testbed comprises PV of various technologies, microturbines, diesel generators, energy storage, artificial loads and an industrial microgrid central controller. The testbed is connected to the low-voltage distribution system which enables it to exchange power with the grid. The microgrid central controller-based remote terminal unit (RTU) and supervisory control and data acquisition (SCADA) were designed to monitor and control the various components within the Microgrid. Some details of the components within the microgrid such as their capacity and manufacturer are provided. The challenges faced by the team during procurement, designing, getting approval, construction and commissioning are shared. The operation scenarios that are performed using the testbed are presented and some data is shared. These include the data on PV generation, load consumptions and power that is exported to the grid. The testbed has been in operation since Sept 2022 with most of its components. Some components however still under commissioning and installation. The successful completion of this project will encourage various companies to adopt the technologies and methodologies as demonstrated with the Microgrid. The Microgrid will also serve as a testing ground for various smart grid concepts before implementing it at a larger scale in the real power system.
