摘　　要：传统最近电压稳定临界点求解方法在全局寻优能力和计算效率之间存在矛盾。为进一步增强光线反射优化(OIO)算法的全局寻优能力,基于House-Holder变换和混合多光源策略提出混合光线反射优化(SOIO)算法。算例分析表明所提方法可有效求解最近电压稳定临界点,计算效率高且全局搜索能力强。Aiming at the contradiction between global searching ability and computational efficiency existing in the traditional methods for calculating the closest critical point of voltage stability,a shuffled OIO（Optics Inspired Optimization） algorithm is proposed based on the House-Holder transformation and a strategy of shuffled light sources to further enhance the global searching ability of 010 algorithm. Case analysis shows that,with higher computational efficiency and better global searching ability,the proposed algorithm can effectively find the closest critical point of voltage stability.
