摘要
针对远离大电网偏远地区采取分布式能源发电的低稳定性和低效率等问题,提出了风光储独立系统的联合控制策略,该策略结合系统功率平衡和蓄电池充放电状态设计工作模式转化控制器进行联合控制。风力和光伏系统的最大功率点跟踪控制(MPPT)采用改进传统变步长扰动观测算法(P&O);负载功率跟踪控制(LPTC)基于功率平衡梯度电压迭代法。最后在MATLAB/Simulink搭建仿真模型,仿真验证该策略能协调风光储三个子系统进行功率转换,使系统稳定运行。
Aiming to solve the problems of low stability and low efficiency of distributed power generation in remote areas far away from bulk power grid, a joint control strategy of independent wind-solar-storage energy system was proposed. Combining with system power balance and the charging and discharging state of battery, a working mode conversion controller was designed for joint system controlling. The maximum power point tracking control(MPPT) of wind and photovoltaic system adopted the improved traditional variable step size disturbance observation algorithm(P&O), the load power tracking control(LPTC) was based on the power balance gradient voltage iterative method. Finally, a simulation model was built in MATLAB/Simulink, and the simulation results show that this strategy can coordinate the three subsystems of the wind-solar-storage system for power conversion and make the system run stably.
