Document Type and Number:
WIPO Patent Application WO/2024/093152
Kind Code:
A1
Abstract:
Disclosed in the present invention is a distributed voltage clamping method for a 100%-new-energy sending-end power grid. The method comprises: (1) selecting key nodes from a 100%-new-energy sending-end power grid, wherein the voltage levels and positions of the key nodes are included; (2) mounting a dynamic reactive compensation apparatus on each key node, wherein all the dynamic reactive compensation apparatuses are controlled by using a constant alternating-current voltage effective value, and instruction values of the alternating-current voltage effective value for the dynamic reactive compensation apparatuses can be changed according to an operation mode; and (3) according to the change condition of an alternating-current voltage of a sending-end system under a typical operating condition, checking whether the selected key nodes can meet requirements, and if the selected key nodes cannot meet the requirements, selecting more key nodes. The control method in the present invention is easily implemented and is highly reliable, can provide a certain reference for future engineering designs, is highly universal, and is theoretically suitable for 100%-new-energy sending-end power grids of various topological structures; and the control method improves the voltage stability of a sending-end power grid by means of clamping the voltages of key nodes, and thus has huge application value in actual engineering.
