摘要

为了研究含双馈风力发电机组的配电网无功电压优化问题

将双馈风力发电机组的无功出力与电容器投切组数和有载调压变压器档位作为控制变量

通过均分次日控制时段使动态无功电压优化问题简化为静态无功电压优化问题。在每个时段开始时利用改进的遗传算法求得使系统网损最低的控制变量组合

每个时段内保持有载调压变压器档位和电容器投切组数不变

通过改变发电机机端电压来进行无功补偿。最后利用改进的IEEE33节点系统进行仿真计算

结果表明利用双馈风力发电机组的无功补偿能力可以有效降低配电网的有功损耗。

Abstract

To discuss the reactive power and voltage optimization problem in distribution power system with the doubly fed induction generators（DFIGs）

the reactive power of DFIGs

capacitor banks and on-load regulating transformers are integrated to be the control variables. The daily control time is equally distributed

so the dynamic optimization problem becomes a static optimization problem. At the time of the beginning of each period

the improved genetic algorithm is used to find the minimal active power loss. In each time period

the capacitor banks and the on-load regulating transformers are fixed

the voltages of DFIGs are used to change the reactive power. Simulation is carried out based on the modified IEEE 33-bus system

and the results show that the method proposed in this paper can reduce the distribution system power loss by providing reactive power of DFIGs.
