Supervisory Control and Data Acquisition systems play a paramount role in the operation of electrical power systems. In this paper, two monitoring systems are developed and applied for self-sufficient hybrid systems based on renewable energy and hydrogen. Siemens WinCC flexible and National Instruments LabVIEW software packages have been used. The first one runs in an operator panel linked with a...
This paper deals with an automation platform to perform R&D tasks on the field of management and control over stand-alone hybrid renewable energy systems. A laboratory scale wind-photovoltaic-hydrogen prototype acts as test-bed to evaluate different control techniques. A successful application of fuzzy logic is reported. Exergy analysis is carried out to determine the efficiency of the main components...
This paper presents the design and validation of a fuzzy logic controller implemented with an industrial programmable logic controller (PLC). The chosen device belongs to the S7-1200 series of Siemens, whereas the code has been developed in Ladder Diagram language using the software TIA Portal. The fuzzy controller is of Mamdani type and is applied to control the speed of a servomotor. A comparison...
