Reactive Power Optimization Configuration of New Energy Sending End System Considering Transient Voltage Stability

To reduce the risk of disconnection caused by voltage instability during operation and failure of the new energy field group transmission system, a reactive power optimization configuration method for the new energy field group transmission system is proposed. Analyze the correlation between reactive power configuration capacity and active power output to determine the reactive power demand capacity that meets steady-state operation, and confirm the configuration position of reactive power devices based on node voltage sensitivity; By combining time-domain simulation, the electrical and economic performance of different reactive power compensation devices are calculated to determine the optimal configuration position, capacity, and combination of different compensation devices for the new energy transmission end system.
