Intelligent power supply restoration in power distribution networks with distubuted generation
Currently the penetration of various forms of distributed generations (DGs) has significantly increased. Such active distribution network with bidirectional power flows brings direct challenges to network control and operation, e.g. increased fault levels and protection degradation. In this paper, an intelligent sequential power supply restoration solution is presented which can be carried out by either reconfiguring network topology or utilization of the embedded DGs for load supply in an island mode, to restore loads as much and quickly as possible. The proposed restoration model mainly considered three kinds of indicators: load recover rate and the current allowance of influenced branches when opening or closing a switcher, and time cost of changing the status of switchers in the sequential restoration process. Whats more, the priority of critical loads were satisfied as far as possible. The performance assessment of two test scenarios is carried out in the 53-bus distributed network and the numerical result verifies the effectiveness of the proposed solution.
