摘要
在可再生能源发电系统中,储能功率调节系统(Power Conditioning System,PCS)将光伏发电系统产生的电能进行调节、转换和储存,以满足用户用电需求。储能PCS的光伏侧直接关系到母线电压,其控制效果直接影响光伏系统的性能和稳定性。故合理的光伏侧控制策略设计对于维护平稳母线电压有重要的意义。为了优化储能PCS的光伏侧控制策略,本文提出了一种恒功率的最大功率点跟踪方法。该方法利用恒功率控制和电导增量法等技术,对光伏系统进行建模和优化。通过对实际光伏系统的数据进行分析和仿真,证明了该方法在提高光伏系统效率和稳定性方面的有效性。
In renewable energy generation systems,the Power Conditioning System(PCS)regulates,converts,and stores the electrical energy generated by the photovoltaic power generation system to meet the electricity needs of users.The photovoltaic side of the energy storage PCS is directly related to the DC bus voltage,and its control effect directly affects the performance and stability of the photovoltaic system.Therefore,a reasonable photovoltaic control strategy design is of great significance for maintaining stable bus voltage.In order to optimize the photovoltaic side control strategy of energy storage PCS,this paper proposes a constant power maximum power point tracking method.This method utilizes techniques such as constant power control and incremental conductance to model and optimize photovoltaic systems.The effectiveness of this method in improving the efficiency and stability of photovoltaic systems has been demonstrated through analysis and simulation of actual photovoltaic system data.
