Research And Realization Of Microgrid Intelligent Power Control System Based On TMS320F28035

Microgrid, the miniature of power system, consists of the small power generation equipment and the load. It can be integrated by biomass, wind, heat and other energy to provide power. So, it can make full use of the energy. Power control system is an important part of the microgrid. In recent years, it has been a hotspot in the research field of microgrid technologies.In this thesis, I described the basis of relevant knowledge of the microgrid in detail, and designed the intelligent power generation control system of microgrid. The paper is mainly to complete the work as follows?Firstly, I had grasped the structure of the turbine, the operation principle and the principle of induction motor power. I established it to run the various parts of the turbine mathematical model and simulation experiments in MATLAB/SIMULINK environment.Secondly, I studied the traditional PID control algorithm and fuzzy control algorithm, and compared the steady-state performance of the output of these signals in depth. And then, I presented the algorithm called double fuzzy control algorithm. The algorithm consisted of two fuzzy controllers, and these controllers were responsible for the elimination of large errors and small errors. Signals before entering the fuzzy controller, would be judged by the fuzzy selector. The selector would distribute the proportion of fuzzy controllers to eliminate the errors intelligently. In addition, the paper also carried out the experimental simulation. The results had shown that, this method had improved the quality of the output signal, reduced the steady state error and shortened the time required for the signal to the steady state with the traditional PID algorithm and fuzzy control algorithm compared.Finally, I designed and implemented the intelligent power generation control system of microgrid with the combination of these studies and methods.Test results show that the system works well in the laboratory environment, and it can connect to the grid but no into the grid. It can generate and control the power intelligently. Also, it has a promising future.
