Multi-fault zone repair method for active distribution network considering the fluctuation characteristics of distributed resources

The existing repair methods may be affected by signal interference, noise, equipment failure and other factors, resulting in inaccurate repair results, which will affect the subsequent fault partitioning and repair work. Therefore, a multi-fault regional repair method for active distribution network considering the fluctuation characteristics of distributed resources is designed. The load of active distribution network is divided into three categories: uncontrollable load, controllable load and adjustable load. The optimal recovery value objective function of load fluctuation is established by considering multiple indexes such as user satisfaction, loss load, network loss and minimum voltage. The experimental results show that the design method has the lowest fault time (0.18 seconds), the best performance in terms of user satisfaction (99.07%), and the best performance in the power loss load (633.16kW).
