摘　　要：多端柔性直流输电系统有功优化分配对交直流系统运行的经济性有很大的影响。建立了一种多端柔性直流输电系统日前优化调度模型,以一天交直流系统总网损最小为优化目标,考虑电压源换流站功率调节范围、调节次数、功率状态的最小持续时间限制和静态安全约束,最后应用遗传算法求解模型。通过IEEE 39节点系统进行验证,优化所得多端柔性直流输电系统有功功率计划曲线,可以有效降低交直流系统总网损,提升系统运行的经济性,同时保证系统运行的安全性。The optimal active power distribution of the multi-terminal flexible direct current(DC)transmission system has a great impact on the economics of alternating current(AC)/DC system operation.A day-ahead optimal dispatching model of multi-terminal flexible DC transmission system was established,in which the optimization goal is to minimize the total network loss of the AC/DC system in a day,considering power adjustment range,number of adjustments,minimum duration of power state and static safety constraints of the voltage source converter station,and finally apply genetic algorithm to solve the model.Through the IEEE 39 node system verification,the optimized active power plan curve of the multi-terminal flexible DC transmission system can effectively reduce the total network loss of the AC/DC system,improve the economy of system operation,and ensure the safety of system operation.
