【摘要】 随着全球能源转型加速，分布式光伏发电项目大量接入配电网已成为常态，但与此同时带来了电压过高、潮流倒送及系统不稳定等问题。为此，提出了一种创新的双层操控策略。通过合理控制光伏的有功和无功输出，维护电力系统的稳定性。首先，采用聚类算法分析配电网中的每个节点，建立集群性能指标；其次，采用融合智能贪婪算法对集群区域进行划分，可在短时间尺度下实现集群自治快速调压；最后，在长时间尺度的群间互治阶段，采用交换方向乘子法协调不同集群间的电压控制策略。集群自治与群间互治二者共同构成双层电压操控策略。通过MATLAB仿真验证，该策略不仅在理论上具有创新性，并在实际应用中展现出了显著的实用性和高效性。更多还原

【Abstract】 With the acceleration of the global energy transition, the large-scale integration of distributed photovoltaic power generation projects into distribution networks has become the norm. However, it simultaneously brings challenges such as excessive voltage, reverse power flow, and system instability. To cope with these challenges, an innovative two-layer control strategy has been proposed. By rationally controlling the active and reactive power output of photovoltaics, the stability of the power system is maintained. In this paper, a clustering algorithm is first employed to analyze each node in the distribution network and establish cluster performance indicators. Secondly, an integrated intelligent greedy algorithm is adopted for the division of cluster areas, enabling rapid autonomous voltage regulation of clusters in a short-time scale. Finally, in the long-time scale inter-cluster mutual governance stage, the alternating direction method of multipliers is utilized to coordinate the voltage control strategies among different clusters. The combination of cluster autonomy and inter-cluster mutual governance constitutes the two-layer voltage control strategy. Verified through MATLAB simulations, this strategy not only demonstrates innovation in theory but also exhibits remarkable practicability and efficiency in practical applications.更多还原
