DC Microgrid Simulator Data Files (Japan 2023)

This dataset contains the MATLAB data files required for the DC Microgrid Simulator developed by Hirohito Yamada (Sendai, Japan).

Version 3.0 introduces a new data-handling scheme in which the simulator directly uses original hourly weather and load datasets. Cubic-spline interpolation is performed dynamically during simulation, significantly reducing memory requirements compared with previous versions.

The dataset includes:

• Plane-of-array irradiance (POA) and temperature-correction data for photovoltaic generation
• Wind-speed data for wind-power simulation
• Residential load profiles for five houses
• EV charging load data

The datasets are provided in MATLAB .mat format and are intended for research on DC microgrids, renewable energy integration, battery management, autonomous distributed control, and disaster-resilient distributed energy systems.
