The increase atmospheric concentrations of greenhouse gases led to an increased demand for clean and renewable energy to replace the burning of fossil fuels. Renewable energy have been highly sought after to electrify both urban and rural areas in the world. With the advancements in renewable technology, the introduction of hybrid grid system proved to be the better option when compared to other systems such as the grid-tied or off-grid system. In this thesis, a supervisory control and data acquisition (SCADA) system for the AC/DC hybrid grid will be introduced. The primary functions of this SCADA system are real time data collection and coordinated control action to achieve an improved reliable, efficient, and sustainable power system. The SCADA system are commonly implemented using programmable logic controller (PLC) and remote terminal units (RTU). However, the SCADA system in this project is implemented using a small central processing unit (CPU) board, beaglebone black. It proved to be at an advantage due to high flexibility and portability and low cost. The SCADA system is implemented by adopting the model-view-controller program architecture and python programming control algorithms that ensure a clear and logical structure with reduced complexity.
