Abstract

In the event of a significant operational fault in the regional distribution network connected to the distributed new energy generator set, it may be necessary to quickly reconfigured certain areas of the system. This process must ensure minimal impact on the voltage of the regional distribution network. To address this issue, a voltage optimal control strategy for regional distribution network based on multi-energy conversion is proposed. Firstly, the energy conversion and adjustable characteristics of electricity, heat, and gas energy conversion equipment in the regional distribution network are analyzed in this paper. The steady-state operation model of the regional distribution network with multi-energy conversion is established. Then, the voltage optimal control model for rapid reconfiguration of the multi-energy distribution network is established by considering the two optimization objectives of power recovery for the important load and system voltage fluctuation. The model is solved based on the greedy algorithm. Finally, an equivalent model of the regional distribution network with multi-energy conversion equipment access is built based on the operation data of the distribution network in a certain area of Northeast China. The feasibility and effectiveness of the model are analyzed and verified.

基于多能源转换的区域配电网重构后的电压优化控制模型

如果与分布式新能源发电机组相连的区域配电网络出现重大运行故障，可能需要快速重新配置系统的某些区域。这一过程必须确保对区域配电网电压的影响最小。针对这一问题，提出了一种基于多能源转换的区域配电网电压优化控制策略。首先，本文分析了区域配电网中电、热、气能量转换设备的能量转换和可调特性。建立了多能源转换区域配电网的稳态运行模型。然后，考虑重要负荷功率恢复和系统电压波动两个优化目标，建立了多能源配电网快速重构的电压优化控制模型。该模型基于贪婪算法求解。最后，根据东北某地区配电网的运行数据，建立了多能源转换设备接入的区域配电网等效模型。分析并验证了模型的可行性和有效性。
