Abstract

In order to meet the power control requirements of power grids in multiple application scenarios, a control technology for power edge-side equipment coordination to suppress power fluctuations in multiple application scenarios is proposed. Firstly, the structure of distributed photovoltaic connected to AC microgrid in multiple application scenarios is analyzed, and the power fluctuation of inverters and filter energy storage inductance components is analyzed to determine the type of photovoltaic power generation power edge side equipment in multiple application scenarios. On this basis, the power fluctuation target is analyzed, and the power control target function is constructed. It predicts the short-term smoothing power of power edge-side devices in multiple application scenarios, and realizes the coordinated power fluctuation control of power edge-side devices in multiple application scenarios based on the vector regulation domain. The experimental results show that the system loss of the method in this paper is small in the fluctuation suppression scenario and typical application scenario, the power fluctuation of the three methods meets the requirements of the national standard, the power of the equipment on the power edge side is relatively stable, and the output power is between 218–224 MW fluctuation, and the power fluctuation rate is small, the maximum power fluctuation rate is 1.5%.
