摘要:
离散无功设备输出变化,如并联电容器投切、有载调压变压器分接头调整等,所造成的设备损耗远大于发电机组、SVG等连续设备。从降低含网损和设备损耗在内的综合成本的角度,本文提出了一种电网无功电压控制协调优化策略,给出了对应的基于改进遗传算法的计算方法。IEEE 14节点系统上的仿真比对结果表明,所提策略比传统的不考虑离散设备损耗的控制策略更为合理,特别是在电网负荷周期变化情况下,所提策略有效地避免了离散设备反复动作。
Abstract:
The loss of output variation of such discrete reactive power devices as shunt capacitor switching and adjustment of on-load tap changer tap is much larger that such continuous equipment as generator unit and SVC etc. In this paper,starting from the point of reducing the comprehensive cost including network loss and equipment loss,a kind of reactive power voltage control coordination optimization strategy of network is proposed,and the corresponding calculation method based on the improved genetic algorithm is given. It is shown by the simulation contrast result on IEEE-14 node system that the proposed strategy is more reasonable than the traditional control strategy without consideration of the discrete reactive power devices loss. The proposed strategy,especially in case of network load periodic change,avoids effectively the repeated operation of the discrete devices.
