采用改进MPC提高储能系统电压暂态特性研究
Research on Improving Voltage Transient Characteristics of Energy Storage System with Improved MPC
摘要
Abstract
The grid-connected operation of an energy storage system is realized by a converter.Due to the low switching frequency of the conventional converter,there exists time delay in sampling and calculation,which will lead to poor transient characteristics of the energy storage system and even instability of the whole power grid.In this paper,model predictive control(MPC)is used to achieve a fast power response of energy storage system and avoid the influence of time delay.A power weight value function is introduced to calculate the optimal output voltage of energy storage converter in the MPC control of active and reactive power.To solve the problem of inaccurate MPC model caused by the parameter deviation of filter inductor,inductance error compensation control is used to improve the model accuracy.Through Matlab/Simulink simulations and experimental results,it is verified that the proposed scheme can improve the transient characteristics of energy storage system and effectively eliminate the influence of error on the MPC control performance.关键词
