چکیده مقاله:
In this paper a new networked distributed fuzzy control scheme is proposed to design the stabilizing signals to damp the low frequency electromechanical oscillations occurred in geographically distributed networked power systems subject to communication network constraints including time delays and packet dropouts. Firstly, through the generic framework of networked systems, a distributed networked model is developed for distributed networked power system (DNPS) in which the network delays and data packet loss are considered in Wide Area Measurement System (WAMS). Then a wide area fuzzy stabilizer is proposed to compensate the influence of WAMS communication delay and damp oscillatory dynamics, which is not susceptible to parameter varying and operating condition changes. In this regard, firstly, the T-S fuzzy controller based on local models is employed to characterize the system dynamic and then a novel distributed fuzzy control design with efficient local feedbacks is suggested to deal with the non-ideal behavior of communication network. The developed method is applied to a networked 5-area-16-machine power grid. Simulation studies verify the superiority and efficiency of the proposed strategy to improve the power grid performance despite of the existence of non-ideal communication network.
