摘要
为了控制供电容量的系统频率,提高传统水电光储系统的年收益,设计基于ST7单片机的水电光伏储能供电容量优化控制系统。硬件设计中,选择ST7单片机作为主要控制芯片,并设计了内部控制和显示电路;软件设计中,建立储能容量优化目标函数,将水电光伏储能设备寿命内所产生的总收益为优化目标,通过对备用容量约束等相关约束条件用公式进行表明,最后通过傅里叶变换,求出可控功率输出的值,实现供电容量的优化控制。实验结果表明系统可明显提高水电光伏储能供电的年收益,具有一定的有效性。
In order to control the system frequency of power supply capacity and improve the annual income of traditional hydropower photovoltaic energy storage system,an optimization control system of power supply capacity of hydropower photovoltaic energy storage based on ST7 MCU is designed.In the hardware design,st7flite05 is selected as the main control chip,and the internal control and display circuit is designed.In the software design,the objective function of energy storage capacity optimization is established,and the total income generated in the life of hydropower photovoltaic energy storage equipment is taken as the optimization objective.The reserve capacity constraints and other related constraints are shown by formulas.Finally,the optimization results are analyzed by Fourier transform In order to achieve the optimal control of power supply capacity.The experimental results show that the system can significantly improve the annual income of hydropower photovoltaic energy storage power supply,and has effectiveness.
