Abstract An active reconfiguration strategy and preventive control system for active distribution network(ADN) considering maximum power supply capability(PSC) are proposed to solve the security problems caused by the increasing number of uncertainties in ADN. Firstly,a PSC index (PSCI) is proposed to evaluate the real-time security level of distribution network by sequential power flow algorithm with variable step size. Then,an active reconfiguration strategy with its preventive control system are proposed for pursuing the maximum PSCI and the minimum number of switch operation of distribution network when the PSCI is lower than a pre-defined warning value,which can significantly increase the reliability of distribution network. Case studies are carried out by using a typical IEEE 33 bus distribution network,and simulation results show the effectiveness of the proposed active reconfiguration strategy and the preventive control system,which has a good engineering application prospect.

Key words： Active distribution network(ADN) on-line security assessment maximum power supply capability index(PSCI) active reconfiguration preventive control
