Analysis of Self-organized Criticality of Ship Power System
Based on self-organized criticality theory and DC power flow,the OPA model of cascading outage in ship power system is established.The OPA model is used to simulate the process of cascading failures in ship power system and reveal the es-sence of blackout in ship power system.The influence of line reliability and line capacity on outage distribution is studied.The re-sults show that enhancing line reliability and line capacity is beneficial to the system against cascading failures.In addition,com-pared with the outage scale distribution of the ring ship power grid structure and the radial ship power grid structure,it is verified that the ring ship power grid structure is more reliable from the perspective of self-organized criticality of the system.
