Maximum Power Prediction of Green Building Energy System Based on Improved Proportional Resonance
A modified proportional resonance control combining proportional resonance control and model predictive control is designed to address the issue of the system output power not reaching the expected value under the influence of meteorological changes,external environmental changes,and internal disturbances in green building power systems.Based on the topology of the green building system,establish a predictive equation for the output power of the green building system,and introduce proportional resonance control.Using output power as the control variable,construct a closed-loop control loop with proportional resonance as the core.Introduce model predictive control in the feedback loop of proportional resonance,and adaptively adjust the error between the expected and output variables in the comparative resonant control to meet the error requirements.Finally,a digital experimental model of the green building power system was built on the MATLAB/Simulink digital experimental platform,and a control loop with improved proportional resonance control as the main strategy was designed.The maximum power output of the improved proportional resonance control,proportional resonance control,and other control strategies was compared,and it was verified that the designed improved proportional resonance control improved the output power of the green building power system.
