Li-SC HESS功率协调分配的PCH强跟踪控制策略
A PCH strong tracking control strategy for power coordinated allocation of Li-SC HESS
摘要
Abstract
The micro-grid usually uses energy storage system to stabilize the power fluctuations of DC bus caused by load changes.This paper uses a lithium battery and super-capacitor hybrid energy storage system (Li-SC HESS) to meet a demand of both the aspects of power and energy due to load changes.This paper researches on the model structure of hybrid energy storage system,and presents a PCH strong tracking control method for power coordinated allocation.Then it combines simscape to simulink,establishes an energy storage system model for photovoltaic micro-grid,and makes a comparative research with the conventional double-loop linear control.The simulation and experimental results show that,the proposed HESS control strategy can effectively reduce lithium battery's charging/discharging times,and smooth its charging/discharging process,with prolonging its service life,thereby improving the performance of HESS.关键词
