【摘要】：激活负荷侧资源的需求响应(DR)潜力是目前智能电网的重要研究课题,但DR资源所具有的海量、多样和互动特点给实时仿真带来了巨大挑战。文中提出了一种集成大规模快速DR资源的智能电网数字实时协同仿真方法。首先,选择解耦点将包含DR资源的电网进行分区解耦,依据动态响应的不同进行多速率仿真。其次,设计了包含双向控制的接口算法以构成协同仿真。然后,分别分析了数字实时协同仿真在微网和高压电网中的典型应用,并采用RTDS和GridLAB-D给出了仿真系统的具体构成。最后,以大规模空调负荷为例验证了所提协同仿真方法的有效性,该方法可以利用通用计算机扩展现有数字实时仿真系统对大规模快速DR资源的仿真能力,具有良好的可扩展性与经济性。
[Abstract]:It is an important research topic of smart grid to activate the demand response potential of load side resources, but Dr resources have a great deal of capacity. Diversity and interaction bring great challenges to real-time simulation. In this paper, a digital real-time collaborative simulation method for smart grid integrated with large-scale and fast Dr resources is proposed. Firstly, the decoupling points are selected to decouple the power grid containing Dr resources. According to the different dynamic response, multi-rate simulation is carried out. Secondly, the interface algorithm including bi-directional control is designed to form collaborative simulation. Then, the typical applications of digital real-time collaborative simulation in micro-grid and high-voltage power network are analyzed respectively. RTDS and GridLAB-D are used to give the concrete structure of the simulation system. Finally, the effectiveness of the proposed collaborative simulation method is verified by taking large-scale air conditioning load as an example. This method can extend the simulation ability of the existing digital real-time simulation system to large scale and fast Dr resources by using general computer, and has good expansibility and economy.
