Research on the Reconstruction of Photovoltaic Power System Grid Based on Production Possibility Boundary

In order to improve the effect of grid reconstruction of photovoltaic power systems and optimize the configuration and operation of power systems, a research on grid reconstruction of photovoltaic power systems based on production possibility boundaries is proposed. Expand the analysis of the output characteristics of photovoltaic power sources, and based on this, consider the multiple impacts of photovoltaic systems on the economic effects, operational safety, and operational modes of distribution networks. Construct a double-layer planning model for photovoltaic fixed capacity in distribution networks based on random fuzzy machine, as well as an optimization model for photovoltaic access points in distribution networks considering transmission losses. Use the normalization method and plane constraint method to obtain the production possibility boundary curve of grid reconstruction composed of multiple sets of optimal reconstruction schemes. Finally, the coefficient of variation method is used to select the optimal reconstruction scheme to complete the grid reconstruction, ensuring that the grid reconstruction of the power system can achieve maximum safety and efficiency. The results show that after the reconstruction scheme obtained by the proposed method is used for grid reconstruction, the voltage fluctuation range can be maintained within [Formula: see text]%, the transmission loss rate is below 2%, and the operating cost is low, with high economic efficiency and safety.
