摘要
为降低随机功率波动及模型参数不确定性对光储一体发电系统稳定性影响,基于传统下垂控制与变系数下垂控制方法,提出一种基于Super-Twisting L_(2)增益自适应的下垂控制方法。为验证所提方法的控制性能,与传统下垂控制以及基于电压变化率的下垂控制相比较,在两种不同光储发电模式下,开展仿真实验与对比分析。仿真结果证明:在光照强度的变化以及负载扰动的条件下,所提出的Super-Twisting L_(2)增益自适应下垂控制的电压波动幅度均比传统下垂控制与变系数下垂控制分别减少6.04%和1.14%,同时在保持光伏输出功率最大输出、下垂系数的快速反应动作等方面都要比传统下垂控制与基于电压变化率的控制性能更加优越。
In order to reduce the influence of random power fluctuation and model parameter uncertainty on the stability of optical storage integrated power generation system,a new method based on Super-Twisting L_(2) gain adaptive droop control is proposed based on the traditional droop control and variable coefficient droop control.In order to verify the control performance of the proposed method,compared with traditional droop control and droop control based on voltage change rate,simulation experiments and comparative analysis are carried out under two different light storage power generation modes.The simulation results show that under the conditions of light intensity change and load disturbance,the voltage fluctuation amplitude of the proposed Super-Twisting L_(2) gain adaptive droop control is 6.04% and 1.14%lower than that of the traditional droop control and variable coefficient droop control respectively.At the same time,it is superior to the traditional droop control and the control based on voltage change rate in maintaining the maximum output of photovoltaic output power and the fast response action of droop coefficient.
