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.

With the rapid increase of renewable energy generation worldwide, real‐time information has become essential to manage such assets, especially for systems installed offshore and in remote areas. To date, there is no cost‐effective condition monitoring technique that can assess the state of renewable energy sources in real‐time and provide suitable asset management decisions to optimize the utilization of such valuable assets and avoid any full or partial blackout due to unexpected faults. Based on the Internet of Things scheme, this paper represents a new application for the Supervisory Control and Data Acquisition (SCADA) system to monitor a hybrid system comprising photovoltaic, wind, and battery energy storage systems. Electrical parameters such as voltage, current, and power are monitored in real‐time via the ThingSpeak website. Network operators can control components of the hybrid power system remotely by the proposed SCADA system. The SCADA system is interfaced with the Matlab/Simulink software tool through KEPServerEX client. For cost‐effective design, low‐cost electronic components and Arduino Integrated Development Environment ATMega2560 remote terminal unit are employed to develop a hardware prototype for experimental analysis. Simulation and experimental results attest to the feasibility of the proposed system. Compared with other existing techniques, the developed system features advantages in terms of reliability and cost‐effectiveness.

Hardware-in-the-Loop Validation of Energy Management Systems for Microgrids: A Short Overview and a Case Study

The energy management system (EMS) of a microgrid often presents a complex structure and a large number of control functions, which must be validated to ensure a reliable and optimal operation of the microgrid. Control system validation is typically performed by using hardware-in-the-loop (HIL) architectures in which the microgrid is simulated in real time and interfaced with the actual system under test. The simulation must ensure both an accurate representation of the microgrid and a reliable replica of the field communication of the EMS with all the control devices. In this paper, an overview of the various HIL architectures proposed in the literature is firstly outlined. Then, an HIL validation facility is presented and used to validate the EMS of an industrial microgrid. Finally, some results of the validation tests are reported to give evidence of the effectiveness of the proposed facility. In the proposed architecture, the soft real-time digital simulator of the microgrid is interfaced with the actual EMS using the same communication system and protocol as on the field. The main advantages of the proposed testing facility are: (i) the use of commercial PCs and the absence of dedicated interface modules, resulting in inexpensive hardware components; (ii) the capability to validate both control and communication functions of the EMS; (iii) the applicability to microgrids of different types (industrial, commercial, residential), as well as of various dimensions, including large microgrids; (iv) the easiness in changing the microgrid and the EMS under validation by only software modifications of the simulator tasks and of the exchange interface. As drawbacks, the proposed testing facility presents the need to adapt the software interface between EMS and the field to the EMS under test and the possibility of testing only the EMS functions and not fast-acting local controllers of the microgrid such as the protection systems.
