Research on simulation test of micro grid coordination controller based on RTDS

微电网是能源互联网的重要环节,而协调控制器作为微电网的大脑,承担着控制指挥的枢纽作用。为验证微电网协调控制器的性能,首先,介绍了微电网电气部分的典型要素和组网方案;其次,基于实时数字仿真系统实时仿真平台搭建了包含各要素的微电网电气仿真系统;然后,设计了协调控制器与实时数字仿真系统之间的实时通信交互组网方案,构成闭环测试系统;最后,依托于该闭环测试系统,对微电网协调控制器的一键式启停、一次调频、后备电源等功能进行了仿真测试,仿真结果验证了协调控制器的各项功能,能够为后续协调控制器在工程现场的调试与应用提供坚实的保障。

Micro grid is an important puzzle of the energy Internet.As the brain of the integrated energy station,the coordination controller assumes the pivotal role of control and command.Firstly,in order to verify the performance of the coordinated controller of the micro grid,the typical elements and networking schemes of the micro grid are firstly introduced.Secondly,micro grid simulation system containing all elements is built based on the RTDS real-time simulation platform.Next,the communication networking scheme between the coordinated controller and the RTDS is designed.Finally,simulation tests are carried out based on the closed loop test system,including one-button start-stop test,frequency modulation test,and backup power supply test.The simulation results verify the functions of the coordinated controller,and can provide a solid guarantee for the subsequent application of the coordinated controller on the project site.
