Multi-source Cooperative Restoration Strategy of Distribution Network Considering Availability of Distributed Generation in Extreme Weather
In order to improve the ability of distribution network to resist and recover from extreme events,it is necessary to give full play to the application potential of massive distribution network elastic resources such as distributed power supply,energy storage system and mobile power supply,and provide support for distribution network power supply recovery through resource scheduling,so as to ensure the functional integrity of distribution network in the whole process of extreme weather to the greatest extent.Therefore,aiming at the fault state of the distribution network and traffic network after typhoon,this paper proposes a multi-source collaborative restoration strategy of the distribution network considering the availability of distributed generation(DG)under the influence of typhoon.A multi-period fault recovery model of the distribution network considering various flexible resources such as distributed power supply,self-provided energy storage and mobile emergency power supply is established,which realizes the rapid recovery of fault load of distribution network after typhoon transit.Firstly,the paper analyzes the availability of DG after typhoon transit.Secondly,it analyzes the shortest travel time and path of mobile resources for the fault state of transportation network.Finally,it uses the IEEE 33 node distribution system and 33 node transportation network for verification.The optimization model is created and solved by MATLAB+YALMIP+CPLEX toolbox.The final results show that the method can effectively use the timing coordination between various flexible resources to support load recovery.
