Power Sharing and Control in Distributed Generation With Wireless Sensor Networks

This paper proposes application of wireless sensor networks in distributed generation. Furthermore, in order to have a reliable communication with minimal end-to-end delay during the event of next hop node failure, the paper proposes a Find Reliable Link (FRL) scheme. Power sharing can be improved significantly in a conventional decentralized power control by correcting the distributed generators reference signals with wireless sensor networks as proposed in this paper. Even a low bandwidth communication among the distributed generators and control center can overcome the system operation challenges posed by network line parameters, failure of distributed generators and power shortage in the system. In order to ensure reliable communication between the sensor nodes or distributed generators and control center, the paper proposes the FRL scheme. The scheme aims to enable the system to make a quick recovery from sensor node failures or link failure due to obstacles thereby reducing the end-to-end delay. The proposed communication scheme is verified by implementing it in Qualnet 5.0. A detail data traffic analysis is presented to demonstrate how reliability is improved in the proposed communication method. Closed loop simulation of communication network with distributed power sources also validates the reliability of the proposed schemes.
