摘要
针对单区域交直流系统受能源类型和机组容量制约,难以实现能源高效利用和频率稳定控制的问题,提出一种考虑多能源互补的多区域交直流系统频率稳定联合控制模型。首先建立单区域多能源能量耦合模型;再基于交直流混联电力系统的能量传递关系,建立交直流系统潮流模型;然后,基于多能源互补和多区域协调,建立考虑多能源互补的多区域交直流系统频率稳定联合控制模型。通过多区域交直流混联系统的算例分析表明,文章所提出的模型具有一定的鲁棒性,可以实现多区域交直流系统频率稳定联合控制,降低系统运行风险。
Aiming at the problem that the single-zone AC/DC system is restricted by energy type and unit capacity,it is difficult to achieve efficient energy utilization and frequency stability control.This paper proposes a multi-zone AC/DC system frequency stability joint control model that considers multi-energy complementation.First,establish a single-region multi-energy energy coupling model;then,based on the energy transfer relationship of the AC/DC hybrid power system,establish an AC/DC system power flow model;Then,based on multi-energy complementation and multi-region coordination,a multi-region AC/DC system frequency stability joint control model considering multi-energy complementation is established.An example analysis of a multi-zone AC/DC hybrid system shows that the model proposed in this paper has a certain degree of robustness,which can realize multi-zone AC/DC system frequency stability joint control and reduce system operation risks.
