Abstract
With the global energy mix transformation, new energy resources, particularly luminous energy, have garnered increasing attention, along with a gradual increase in their proportion in the electric power sector. However, challenges in new energy resource consumption and system planning persist. Therefore, this study develops a power supply planning model based on a photovoltaic (PV) microgrid system. This model can be applied to improve the consumptive ability of new energy resources, optimize the power combination, and realize the sustainable development of the power system. System modeling and simulation analysis are conducted using MATLAB/Simulink software to analyze the electrical output characteristics for PV microgrid system optimization. PV power and direct current load models are initially established, and the effects of different parameters on the power curves are analyzed. The results demonstrate that the developed mathematical models are effective in simulating the electrical output characteristics of PV microgrid systems. Additionally, the model optimizes the power supply, supporting the sustainable development of the power system. Adjusting the model parameters significantly influences the system output, which is valuable for designing and optimizing PV power generation systems.
