Based on design information and on-site observations, the loads acting on photovoltaic supports primarily include the weight of the photovoltaic panels, the wind load, the snow load, and the construction load. Additionally, the Chinese code NB/T 10115-2018 mandates the consideration of the longitudinal wind load on photovoltaic supports.
Based on a typical photovoltaic support failure case, this study involved detailed research on the design load and joint connection measures of photovoltaic supports. First, the general design software SAP2000 (V22.0.0) was utilized to compare the loads in photovoltaic support structure design among Chinese, American, and European codes.
A composite load model of a distribution feeder, including DPV, is developed to assess the effectiveness of the proposed frequency support algorithm in power systems with high penetration of DPV inverters.
This article proposes a frequency droop-based control in DPV inverters to improve frequency response in power grids with high penetration of renewable energy resources. A predefined power reserve is kept in the DPV inverter, using flexible power point tracking. The proposed algorithm uses this available power reserve to support the grid frequency.
Finally, a photovoltaic power generation output prediction model was constructed based on least squares support vector regression, and the solution of the model was completed. The
