摘要:

随着分布式能源(distributed generation, DG)的大规模接入，电力系统在提升供电可靠性方面遭遇了诸多挑战，如功率平衡、电压稳定性以及电能质量问题。为有效应对这些挑战，构建了一种兼具时空可控性的移动储能系统 (mobile energy storage system, MESS)与柔性软开关(soft open point, SOP)协同优化模型，并考虑动态交通信息对 MESS 的行驶路径进行优化，从而在时空尺度上实现电力的合理分配。在优化过程中，以最大化净效益和最小化总电压波动作为目标函数，旨在兼顾经济性和稳定性。采用基于参考点的非支配排序遗传算法 III(non-dominated sorting genetic algorithm III, NSGA-III)进行求解，并结合改进灰靶决策(improved grey target decision making, IGTDM) 方法筛选出最佳折中解。通过对云南省玉溪市某区域路网和33节点电网系统的算例分析，验证了SOP与MESS 协同优化对配电网性能提升的有效性，特别是在提高供电可靠性方面。结果表明，接入SOP和MESS后，配电网的网损显著降低，电压波动大幅减小，系统的稳定性和经济性得到显著提升。具体而言，优化后净负荷峰谷差由 1.88 MW 降至1.53 MW，下降约18.6%；总电压波动由0.244 p.u.降至0.0811 p.u.，降幅达66.8%。

Abstract:

With the large-scale integration of distributed generation, power systems are encountering many challenges in improving power supply reliability. A coordinated optimization model integrating mobile energy storage system and flexible soft open point is constructed. Dynamic traffic information is incorporated to optimize the routing of mobile energy storage system. The model is solved using NSGA-III, and the optimal compromise solution is identified by improved gray target decision making. Results show that network losses are greatly reduced, voltage fluctuations are substantially mitigated, and both system stability and economic performance are significantly improved.

Key words: soft open point mobile energy storage system power supply reliability voltage fluctuation distributed generation
