The invention is suitable for the technical field of power distribution network planning, and provides a power distribution network dynamic island division method and terminal equipment. The method comprises the steps of according to the output information of a distributed power supply and an energy storage device in each time period, the charging and discharging information of an electric vehicle, and the fluctuation information of a load, determining an island range set of any node in N time periods in one day, judging whether the island ranges in the island range set are intersected or not, and if the island ranges are intersected, taking the intersection of the island ranges and the maximum island range in the island range set as the final island range of the corresponding node, or otherwise, taking the maximum island range in the island range set as the final island range of the corresponding node. The final island range determined based on the island range set of each time period is more beneficial to formation of a reliable island operation range after the power distribution network has a fault.
Description
technical field [0001] The invention belongs to the technical field of distribution network planning, and in particular relates to a dynamic island division method and terminal equipment of a distribution network. Background technique [0002] With the strengthening of distribution network construction and the maturity of micro-grid technology, and in order to promote energy conservation and emission reduction and combat climate change, the country vigorously develops renewable energy and reduces the consumption of fossil energy. Therefore, in the future, the access capacity of distributed generation (DG) in the distribution network will be greatly increased. In addition, more and more electric vehicles (Electric Vehicles, EV) will be connected to promote energy conservation and emission reduction. [0003] However, various distributed power sources and electric vehicles are connected to the distribution network. While improving economic benefits and promoting energy conserv...
