Electrical Output Simulation Model Establishment about Photovoltaic Microgrid

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, a reasonable power planning model need to be built, from which the consumptive ability of new energy resource can be improved. The power combination is optimized. The sustainable development of power system can be realized. This study develops a power supply planning model that improves the consumptive ability of new energy resources. Specifically, this study presents a power supply planning model based on a photovoltaic (PV) microgrid system. System modeling and simulation analysis were conducted using MATLAB/Simulink, analyzing the output characteristics of PV microgrid system optimization. Initially, models for PV power and direct current load were established, and the effects of different parameters on the power curve were analyzed. The results demonstrate that the mathematical models are effective in simulating the output characteristics of PV microgrid systems. Additionally, the model optimized the power supply, supporting the sustainable development of the power system. Adjusting the model’s parameters significantly influences the system output, which is valuable for designing and optimizing PV power generation systems.
