New energy grid connection is easy to cause voltage fluctuation, frequency oscillation and other problems. For this, the paper adopts a frequency division control strategy of hybrid energy storage unit, which based on the storage of photovoltaic grid-connected system as the research subject, thus improving the dynamic stability of DC bus voltage, and proposes an improved virtual synchronous generator. According to the characteristics of flexible adjustment of inertia parameters, the virtual inertia and parameters are adjusted adaptively to suppress the frequency and power oscillation caused by the disturbance. Finally, a simulation model of photovoltaic storage grid-connection is established. It verifies that the proposed strategy can not only stabilize the DC bus voltage and supplement the power deficiency under different operating conditions. At the same time, it can slow down the sudden change of the system frequency and reduce the overshoot, showing good grid-connected performance.

针对新能源并网容易引发电压波动、频率震荡等问题,以光储并网系统为研究主体,采用混合储能分频控制策略来提升母线电压动态稳定性,并提出一种改进虚拟同步机控制策略,针对惯性环节参数可灵活调节的特点,对虚拟惯量和参数进行自适应整定,抑制扰动带来的频率和功率振荡。进而建立光储并网仿真模型,在不同工况下验证所提策略不仅能良好地稳定母线电压,补充光伏功率缺额,同时可减缓系统频率突变和减小超调,体现出更友好的并网性能。

针对新能源并网容易引发电压波动、频率震荡等问题,以光储并网系统为研究主体,采用混合储能分频控制策略来提升母线电压动态稳定性,并提出一种改进虚拟同步机控制策略,针对惯性环节参数可灵活调节的特点,对虚拟惯量和参数进行自适应整定,抑制扰动带来的频率和功率振荡。进而建立光储并网仿真模型,在不同工况下验证所提策略不仅能良好地稳定母线电压,补充光伏功率缺额,同时可减缓系统频率突变和减小超调,体现出更友好的并网性能。

New energy grid connection is easy to cause voltage fluctuation, frequency oscillation and other problems. For this, the paper adopts a frequency division control strategy of hybrid energy storage unit, which based on the storage of photovoltaic grid-connected system as the research subject, thus improving the dynamic stability of DC bus voltage, and proposes an improved virtual synchronous generator. According to the characteristics of flexible adjustment of inertia parameters, the virtual inertia and parameters are adjusted adaptively to suppress the frequency and power oscillation caused by the disturbance. Finally, a simulation model of photovoltaic storage grid-connection is established. It verifies that the proposed strategy can not only stabilize the DC bus voltage and supplement the power deficiency under different operating conditions. At the same time, it can slow down the sudden change of the system frequency and reduce the overshoot, showing good grid-connected performance.
