Abstract:

Aiming at the problems in the experimental teaching of energy storage, this paper uses hardware-in-the-loop simulation technology to incorporate specific actual engineering projects into the experimental teaching. The authors use Simulink to model the energy storage controlled object, use the designed low-code controller for control, and propose an experimental teaching method for energy storage control based on Simulink and low-code controller. The specific process of the method is as follows: in the preparation phase of the experiment, the teacher assigns the students the task of understanding the background of the experiment in advance. During the experiment, it is divided into four parts: control strategy design, controlled object model construction, control strategy realization and result analysis. After the experiment, students are encouraged to deep thinking and extend to other control strategies. Then authors introduce the low-code controller and explain the configuration files in detail. Students only need to fill in the corresponding EXCEL configuration file to realize the control strategy, which reduces the requirements for programming ability and helps them understand the control strategy more thoroughly. Finally, taking the optimization control of energy storage power allocation as an example, it is carried out from four aspects: overall cognition, key enhancement, difficulty analysis and in-depth enlightenment. It completes the real-time simulation of energy storage battery pack charging and discharging, realizes the control goal of energy storage power distribution, verifies the accuracy of hardware-in-the-loop simulation technology and the validity of the proposed energy storage control experiment teaching method.
