Microgrid operation dataset

What are the components of a microgrid?

The main components of interest in the microgrid to this study are the four arrays of solar panels, a lead-acid battery, and a pyranometer (see Fig. 1 ). There is also a backup power generator, which can be initiated during emergency power failures, although this has not occurred during the period of data recording.

What is the advanced microgrid?

The advanced microgrid contains several distributed energy resources (DERs), such as solar power plants, electric vehicles, buildings, a combined heat and power gas-fired power plant, and electric and thermal storage. Most datasets contain 15-min averages of real and reactive power from 1 January, 2015 until 29 February, 2020.

What is a microgrid & how does it work?

The microgrid operates a natural gas fired combined heat & power plant that provides district heating and cooling to most buildings on the campus. The plant consists of two 13.5 MW natural gas turbines, a steam generator, electric chillers, and a chilled water tank for thermal energy storage.

How does a microgrid interact with a grid?

As per the conditions in the condition-based operation (Figure 7), grid interaction depends on a careful assessment of the internal grid balance. The microgrid refrains from importing power when its needs are met internally, and power export is limited to surplus wind-generated power.

What data formats are available for Microgrid data?

The microgrid data is available in both raw and cleaned formats for data per second. In addition, the data per second has been summarised into hourly data for easy comparison. To enable understanding of the different recorded parameters, their machine codes, and Japanese labels, Table 4 provides their translation/description.

What happens if a microgrid fails?

Any remaining power () is either wasted (in island mode) or exported (in grid mode). When wind power falls short, the MGT operates at its lowest feasible power. If the MGT reaches maximum power but cannot meet demands, any shortfall must be imported (in grid mode). A microgrid failure (island mode) is rare but considered a “warning alarm.”
