Design and Research of an Intelligent Photovoltaic Energy Storage System

能源短缺以及环境问题是制约城市发展的重要因素,太阳能作为一种潜在的可再生新能源,在未来的城市发展上有重大的意义。传统的光伏发电系统易被外界因素干扰,从而导致输出功率随机且十分不稳定,严重制约的光伏能源的发展。针对该问题提出了一种智能光伏能量存储系统方案,该方案基于超级电容和蓄电池的组合型能源存储系统以及粒子群智能控制算法,研究了一种功率分配控制策略,通过理论分析和MATLAB/Simulink验证,得出该光伏储能系统的输出电压稳定,不受外界因素的干扰,如负载功率以及光照强度变化等,在系统的能源部署上具有一定的参考价值。

Energy shortage and environmental problems are important factors restricting urban development.As a potential renewable new energy,solar energy has great significance in the future urban development.The traditional photovoltaic power generation system is easy to be interfered by external factors,resulting in random and unstable output power,which seriously restricts the development of photovoltaic energy.Aiming at this problem,an intelligent photovoltaic energy storage system is studied.Based on the combined energy storage system of supercapacitor and battery and particle swarm intelligent control algorithm,a power distribution control strategy is studied.Through the theoretical analysis and verification of Matlab/Simulink,it is concluded that the output voltage of the Table photovoltaic system is not affected by external factor,such as load power and light intensity changes,etc.,which has certain reference value for the energy deployment on the system.
