DER (Generic) Control Join
Description of the DER (Generic) Control Join component, for enabling easy selection of control signals of interest in order to enable model control of a Generic DER component inverter.
The DER (Generic) Control Join is a component located in the Infrastructure section of the Distributed Energy Resources section of the Microgrid Library. Component icon and properties window are shown in Table 1. The DER (Generic) Control Join is a masked bus join that is compatible with the signal processing control inputs 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 purpose is to enable easy selection of control signals of interest in order to enable model control of the converter. Signals that are not selected to be fed externally are sent in the form of constant, default values.
Component inputs are scalar values, while its output is a fixed size vector. Its size and number of output ports are changed dynamically based on chosen measurements. For a more detailed information on meaning of each control signal, please refer to documentation of a corresponding DER (Generic) component.
