A NOVEL LOW-COST MONITORING AND CONTROL SOLUTION FOR PHOTOVOLTAIC SYSTEM INTERGRATING INTO UTILITY DISTRIBUTED GRID
Abstract
The electric industry is poised to make the transformation from a centralized, producer-controlled network to one that is less centralized and more consumer-interactive. A smarter grid makes this transformation possible by bringing the philosophies, concepts and technologies that enabled the internet to the utility electric grid. In this study, proposing of a novel islanding detection method is one of the most important features and offering a method of combining the measurement solution and communication media based on the development of electronic communication devices that new technology systems to detect the islanding state in point of common coupling (PCC) for power grid connected to DGs; based on the structure of SCADA. The simulated results of test case on the Matlab/Simulink enviroment has demonstrated the effectiveness of the proposed methods.
