Reliability assessment of active distribution network considering aging effects of multiple devices
The large-scale access of high proportion of renewable energy has promoted the transformation of the dis-tribution network to the active distribution network(ADN),and a large number of information equipment construc-tion has expanded the overall scale of the active distribution network and improved the efficiency of information pro-cessing,but at the same time,it has also made the problem of safe and reliable operation of the system more promi-nent.This paper proposes a risk assessment method for smart distribution network of hybrid communication network considering aging effects.Firstly,the failure mode and effect analysis method is used to establish the fault correla-tion model between the information network and the distribution network,and then the Weibull distributed aging failure model of information equipment and physical equipment is established by using equipment performance pa-rameters.Finally the system reliability is evaluated by the simulation method combining sequential and non-sequen-tial Monte Carlo.The result can provide strong technical support for the operation and maintenance of active distri-bution networks in future.
