【Abstract】 Aiming at the defect of long time checking sort in solution space for the traditional OBDD algorithm in fault recovery process,this paper puts forward an improved OBDD algorithm to study the influence of distributed generation with black start capability and interruptible load on the failure recovery of distribution system.Numerical examples show that the method can get the global optimal stability failure recovery plan and improve the efficiency of the decision-making.Island operation mode greatly exerts DG power supply capacity and improves the system reliability.Interruptible load plays an important role in expanding the scale of power grid failure recovery and improves supply reliability of the important load.更多还原
