Research on Power Optimization Allocation Method for Solar-Hydrogen-storage Coupled System Based on Model Predictive Control
摘要
Abstract
In view of the issue of Intermittency and volatility in photovoltaic(PV)power generation,the control strat-egy of solar-Hydrogen-storage coupling system is studied and a model predictive control(MPC)method for power allocation method in the'solar-Hydrogen-storage'system is proposed.First,the overall structure of the solar-Hydro-gen-storage coupled system is constructed,in which the Hydrogen energy system includes PEM electrolyzers,Hydro-gen fuel cells and the Hydrogen storage tank.Then,based on the power balance equation of the solar-Hydrogen-stor-age coupled system,a state-space model is constructed,and the PEM electrolyzer power and Hydrogen fuel cell pow-er are taken as control variables.Various constraints within the system are identified,and the MPC optimization prob-lem is adjusted to QP problem for solution.An MPC controller is constructed by using the s-function module and the closed-loop simulation of the system is completed.The effectiveness of the proposed MPC real-time power allocation method is verified through simulation analysis.关键词
