Use
The PV2AC converter model is necessary to couple a photovoltaic system model with an AC-grid.
Parameters and Connectors
Basic
The converter connects a PV system (▶DCPV) and an AC grid (▶Grid). The photovoltaic converter uses the resulting maximum-power-point voltage (▶MPP) to control the intermediate-circuit voltage on the PV-side. Make sure that ▶MPP-connector is connected with the correspondent PV system. This ensures that the PV systems provides maximum electrical power output at all times. The maximum voltage of a 3-phase converter is 2.34 times the effective grid voltage. The parameter etaInverter represents internal losses of the converter and reduces the power output to the DC grid. The power factor CosPhi of the inverter defines the ratio between the real and the apparent power. This configuration uses the DCDCConverter model and the B6 converter.
Model Background
A PV system is normally, controlled by MPP-Tracker, a system regulating the intermediate-circuit voltage at PV-side without knowing the actual available MPP-voltage and current. Such a tracker uses measurements for voltage and current output for power regulation. These complex control algorithms are not included to reduce system complexity in the provided controller model.
