| 中文摘要 |
| 在风/光互补发电系统中, 风、光资源的随机性强, 导致系统电压的稳定性差, 电压控制显得尤为重要. 电压控制通常通过区域无功功率的优化来实现. 无功功率优化是一个带有约束的多极值非线性组合优化问题, 用传统的方法很难进行处理. 因此提出一种改进的遗传算法用以风光/互补发电系统的无功功率优化, 该算法在一般遗传算法的基础上, 对编码方式、遗传算子以及终止判据等方面作了改进. 通过算例分析表明, 改进的算法能够显著的提高收敛速度和计算精度, 有效的实现电压的无功控制. |
| 英文摘要 |
| In the wind/photovoltaic hybrid power generation systems, with strong fluctuation of wind and photovoltaic resources, the stability of voltage becomes low. So voltage control is of the utmost importance for wind/photovoltaic systems. Voltage control is usually implemented by the optimization of local reactive power. The optimization of reactive power is a non-linear combination optimization problem with constraints and multi-extrema. It is very difficult to solve by the traditional methods. So an improved genetic algorithm (IGA) is designed for optimizing reactive power in the wind/photovoltaic hybrid power generation systems. Based on the simple genetic algorithm, the algorithm is improved with the method of coding, operators and termination conditions. Experimental results show that the improved algorithm can remarkably improve the convergent speed and calculational precision, and implement the reactive power and voltage control more efficiently. |
