研究目的
To propose a method that is able to maintain the DC Microgrid network voltages during load demand fluctuations, while the PVs and ESSs generate power outputs according to their designated capacities.
研究成果
The proposed method successfully maintains the DC Microgrid network voltages within acceptable limits during load demand fluctuations and regulates the generated power by PVs and ESSs according to their capacities across three operational modes. The simulation results demonstrate the method's effectiveness in managing power flow and voltage stability in a DC Microgrid.
研究不足
The study is based on computer simulation, which may not fully capture real-world operational complexities. The line impedances and load demands are idealized, and practical implementations may face additional challenges.
1：Experimental Design and Method Selection:
The study employs a computer simulation approach using Matlab Simulink to evaluate the performance of the proposed power control method in a DC Microgrid network consisting of PVs and ESSs.
2：Sample Selection and Data Sources:
The simulation models a DC Microgrid with a single PV, line impedances, a single ESS, and loads.
3：List of Experimental Equipment and Materials:
The simulation setup includes DC-DC converters, MPPT controllers, and a load with specified parameters.
