Currently, the generation of energy relies primarily on the usage of harmful fossil fuels all over the world. New technologies, on the other hand, have enabled renewable energy resources to have a reduced environmental effect, greater long-term sustainability, and, in some cases, to be cheaper than fossil fuels. Microgrids that use renewable resources can deliver low-cost clean electricity while also improving local resiliency. They do, however, have certain issues in terms of regulating internal frequency and voltage within a microgrid, which is hampered by the intermittent nature of renewable sources. An islanded Microgrid for San Andres, Colombia has been designed for 24.57 kW peak load composed of a PV-wind-storage system by considering dispatch strategy based control in Homer Pro and assessed utilizing Simulink/MATLAB. Lastly, a PLC-SCADA system along a HMI (Human-Machine Interface) in C# was created to monitor the Microgrid in real-time and produce an alarm as the microgrid elements are not operating within their ideal range of operational. The data from HMI is automatically uploaded to a cloud database. This work incorporates the dispatch control based techno-economic design, assessment and a complete supervisory control strategy for an optimum microgrid.
