[0173] 1. Basic data

[0174] right figure 1 Multi-time-scale optimal scheduling analysis of day-ahead and day-to-day in building micro-grid. The day-ahead scheduling forecast data is hour-level forecast data, and the daytime scheduling actual measurement data is 15-minute level data. The building in the building micro-network is set as a single-family office building with a length of 30m, a width of 20m, and a floor height of 3m, with a total of three floors. The exterior wall of the building adopts 190mm single-row hole bricklaying, and 25mm thermal insulation mortar inside and outside; the windows are made of PVC plastic windows, and the glass is ordinary insulating glass. The relevant building parameters are shown in Table 1. The calculation example selects a typical day in summer i...
