Wireless communication system for microgrids management in islanding

Microgrids (MGs) are promising electrical systems based on Distributed Generation and with high penetration of renewable energy sources. One important feature of MGs is the islanding capability: if there is a disturbance in the main grid, the MG will be automatically disconnected. In theory, once in islanding, the MG can continue the electrical generation but, in practice, the generation is stopped in order to avoid injuries and accidents. Therefore, the management systems utilized in MGs must be improved in order to allow a safe operation in islanding. This paper presents a wireless communication system for MGs management based on SimpliciTI protocol. The communication procedure, including security, and the MG controllers with their measure system are described in depth, and the correct operation of the proposed solution is also verified.
