Navy ship power system restoration using multi-agent approach

Power transmission lines of traditional power transmission systems (PTSs) may suffer from some faults that can lead to blackouts. This work proposes a methodology to construct hierarchical distributed control systems (DCSs) for the automatic fault detection and restoration of PTSs using colored Petri nets (CPNs). If faults occur in power transmission lines, they can be detected by supervisors, and local solutions can be computed to restore the faults. Each supervisor is coordinated by a coordination protocol to perform the computation of local solutions. The structures of traditional PTSs are simplified and defined by CPNs, and the derivation processes of fault detection and restoration based on the proposed coordination protocol are verified by the mathematical methods of CPNs. Finally, the complexity of the proposed hierarchical DCS and coordination protocol is discussed and an example is given to illustrate the proposed method. © 2018 Institute of Electrical Engineers of Japan.

As the important infrastructure of power transmission systems, the power transmission lines are vulnerable during the peak power transmission periods. They usually meet many faults that may cause large area blackouts because of heavy loads. This article proposes a supervisory control strategy to promote the detection and restoration of power transmission failures during the peak or off-peak periods. The faults occurring in power transmission lines can be detected, and fault restoration schemes can be selected by supervisors. Moreover, the architecture of distributed control systems is proposed to perform message switching among supervisors. A coordination protocol that is executed by each supervisor is proposed to selected fault restoration schemes. The proposed strategy can not only detect and restore power transmission failures but also improve the utilization rate of available loads in power transmission systems. The proposed distributed control systems and coordination protocol are modeled by synchronized Petri nets. The correctness of fault restoration is verified using the mathematical methods of Petri nets. Finally, the complexity of the proposed distributed control systems and coordination protocol is discussed, and a real-world example is given.

“…In the proposed MAS, local bus agents formulate a restoration plan through negotiation, and then check the restoration plan with a global facilitator. In [17], a multi-agent-based approach for navy ship system electric power restoration is provided to restore the capacity as much as possible to serve the loads.…”
