摘要

针对新能源高渗透率下多时间尺度电压协同控制存在经济性与实时性难以协调的问题,提出基于边云架构的多时间尺度电压协同控制方法。针对新能源消纳场景下离散/连续设备协同调节难题,将电压协同控制分为3个阶段：云端针对离散型设备进行小时级的控制以实现全局的功率损耗和调压成本最低;边缘控制器则以15 min为周期对连续型设备进行控制以应对较短时间尺度内的功率波动;对于实时的功率波动和设备故障等则基于事件触发通信机制实现电压实时控制。设计面向边云协同电压控制的交替乘子法求解策略,以提高计算和通信资源的使用效率。改进IEEE配网算例的仿真结果表明：在新能源高渗透率场景下,所提方法在平均/最大电压偏差分别降低2.3%/16.3%;在通信和计算资源分配不平衡指数和总求解时间上的提升幅度均超过68%。通过协调不同时间尺度的调压资源,可显著增强系统对可再生能源波动的适应性,网络损耗降低超6.2%,验证该方法在提升新能源消纳方面的有效性。

Abstract

Aiming at the problem that it is difficult to coordinate the economy and real-time performance of multi time scale voltage collaborative control under the high renewable energy penetration, a multi-time scale voltage cooperative control method based on edge cloud architecture is proposed. To address the co-regulation problem between discrete and continuous devices in the context of renewable energy consumption, the voltage co-control process is divided into three stages： First, the cloud system manages the discrete equipment on an hourly basis to minimize global power loss and reduce regulatory costs. Second, the edge controller regulates the continuous equipment at 15-minute intervals to effectively respond to short-term power fluctuations. Finally, to manage real-time power fluctuations and device failures, the voltage control method employs an event-triggered communication mechanism to facilitate immediate voltage regulation. An alternating direction method of multipliers （ADMM） solution strategy for cooperative voltage control, oriented towards edge-cloud applications, is designed to enhance the efficiency of computational and communication resource utilization. Simulation results from an improved IEEE distribution network demonstrate that the proposed method reduces the average and maximum voltage deviations by 2.3% and 16.3%, respectively, in a scenario with high penetration of renewable energy sources. Additionally, it improves the imbalance indices of communication and computation resource allocation, as well as the total solution time, by more than 68%. By coordinating voltage regulation resources across different timescales, the system’s adaptability to fluctuations in renewable energy is significantly enhanced, resulting in a reduction of network losses by over 6.2%. This verifies the effectiveness of the method in promoting renewable energy consumption.
