Due to the dual pressures of environmental pollution and energy depletion,we have made great efforts to develop clean and renewable energy,and the micro grid technology has also made significant progress.The power qualit y of the micro grid directly determines its stability,and the independent operation of the micro grid mainly through the energy storage inverter to provide energy support.The capacity of the micro grid is small,and the change of the load is easy to caus e the fluctuation of the system voltage.In order to guarantee the power quality,the energy storage inverter control algorithm which can provide stable voltage support is required.The control algorithm of the inverse model of the support vector machine i s designed for the energy storage inverter.Firstly,the basic principle of SVM algorithm is introduced,and the inverse model control algorithm based on SVM is analyzed.For the single-phase energy storage inverter,analyzing its topology structure,mathe matical model and common control algorithm,and analyzing the influence factors of the output voltage,the inverse model of support vector machine to determine the form,given for storage support vector inverter control design of inverse control algorithm.Secondly,the simulation model of energy storage inverter is built by Simulink,the operating state of the energy storage inverter in different operating conditions is simulated,the data are collected and the inverse model of the support vector machine is trained.In order to solve the problem that the support vector machine parameters are difficult to determine,the optimization algorithm is used to optimize the parameters,and then the inverse model control algorithm of the support vector machine is constructed.Through simulation experiments,the double closed-loop PI control algorithm is compared,and the feasibility and effectiveness of the inverse model control are verified.Finally,expounds the application of parallel computing method and support vector machine based on FPGA,using Quartus II software,using Verilog HDL hardware description language,realizes the energy storage inverter SVM inverse model control algorithm,this paper introduces each functional module of the RTL diagram and its working process.The feasibility,correctness and rapidity are verified by Modelsim simulation software.
