The power outage maintenance has a significant influence on the security and economy for distribution system operation and the reliable electric supply. Therefore

a multi-objective distribution network reconfiguration method is proposed considering the power outage maintenance and operation risks. Firstly

a comprehensive objective for distribution network reconfiguration based on improved entropy weight method is constructed

which takes the optimal operating economic cost

optimal load rate

and optimal voltage quality as the multi-objective of distribution network reconfiguration to reflect the economic and security of distribution network operation. And then

an optimization model for multi-objective distribution network reconfiguration with power outage maintenance is constructed

in which the coupling constraints between power line maintenance and grid operation are considered on the basis of distribution network reconfiguration constrains. Finally

the simulation is carried out with the improved standard IEEE case to verify the effectiveness of the proposed method. The simulation results show that the obtained strategies considering power outage maintenance and operation risks by the proposed method can effectively depress the influence of power outage maintenance on the distribution network operation

lower the operation risk

increase the security margin and promote the economy and security of distribution network operation.
