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.
