Using the Voltsys Power Curve Control system, we can use ABB solar inverters to export power from wind or hydro systems to the grid. Our systems can also be used in off-grid applications.
What is an Inverter?
An inverter takes DC current, usually from a solar panel, wind turbine or hydro generator, and converts it to a voltage and frequency suitable for export to the grid.
How much energy it exports is determined by the inverter. For solar power, maximum power point tracking (MPPT) is used to keep solar panels at an optimum DC voltage and current to maximise power production.
Wind Turbine Power Curve
Small turbines usually run at a variable speed, and as the speed increases, the power available also increases exponentially. For wind and hydro, you need to produce a “power curve” which is a table outlining how much power an inverter should convert to the grid based on either turbine RPM or voltage. A typical power table looks like the chart seen here;
Voltsys Controllers are connected to the turbine and can read RPM and DC voltage. From this, they can instruct the inverter how much power to export, so that solar inverters can now be used to control the output from wind turbines.
