Low Cost Wireless Sensor Network in Distributed Generation

This paper proposes an application of low cost IPv6 based wireless sensor network in distributed generation. The wireless sensor network used in the proposed scheme is based on IEEE 802.15.4 link layer technology and the sensor nodes have the ability to communicate directly with other IP devices via internet. A web based service is appreciated for implementing the proposed smart power distribution and efficient power management system. Even a low bandwidth communication among the distributed generators and load centers can overcome the system operation challenges posed by network line parameters, failure of distributed generators and power shortage in the system. Power management can be improved significantly in a conventional decentralized power control by correcting the distributed generators reference signals as proposed in this paper. In order to ensure reliable communication between the sensor nodes or distributed generators and load center the paper proposes FRL scheme, which aims to determine the most reliable link for a sensor node on fly. This paper shows stable operation of the system for a range of operating conditions while ensuring reliable data transfer among the distributed generation.
