DER (Generic) Output Split

This section describes the DER (Generic) Output Split component from microgrid library.

The Meter Split is a component located in Infrastructure section in Distributed Energy Resources section of Microgrid Library. Component icon and properties window are shown in Table 1. The DER (Generic) Output Split is a masked bus split that is compatible with the signal processing outputs of the DER (Generic) components: Battery ESS (Generic), PV Power Plant (Generic), Wind Power Plant (Generic), Diesel Genset (Generic), and Bidirectional AC-DC Converter (Generic). Its inputs are vectors of fixed size, while its outputs are scalar values. Its size and number of output ports are changed dynamically based on the selected component and chosen measurements.
