摘要:

配电网中空调负荷的规模随着生活水平的提高在快速增长,而带有空调的建筑具有热缓冲能力,使其具备了参与需求侧响应的价值。与此同时,分布式光伏发电在配电网中的渗透率也在逐步提高。光伏发电的波动对配电网电压稳定性造成了消极的影响。文中提出一种基于分布式趋同控制的方法,通过聚合商之间建立的有限通信链路对聚合空调负荷进行调度,以参与到配电网的电压管理中。其中,采用二维热工参数模型,从而更准确地计算带有空调的建筑热交换,使得用户的热舒适性需求得到保障。最后,基于改进的IEEE 15节点配电网算例分析验证所提控制策略的有效性和鲁棒性。

Abstract:

The scale of air-conditioning load in distribution network is rapidly increasing with the improvement of living standard. Furthermore, air-conditioned buildings have the capacity of thermal buffer, which makes it valuable for participating in demand-side response. In the meanwhile, the penetration rate of distributed photovoltaic (PV) power generation in distribution network is gradually increasing. The fluctuations from PV generation have a negative impact on the voltage stability of distribution network. This paper proposes a distributed consensus-driven control method. The aggregated air-conditioning load is scheduled to participate in the voltage management of distribution network through the limited communication links established between the aggregators. A two-dimensional thermal parameter model is adopted to calculate the thermal dynamic exchange of air-conditioned building more accurately to guarantee the thermal comfort requirement of users. Finally, the case studies are performed on a modified IEEE 15-node distribution network to verify the effectiveness and robustness of the proposed control strategy.
