Abstract: A system for online filtering of photovoltaic (PV) output signals includes a programmable filter that is programmed to decompose measured PV output power into an estimated low-frequency signal component, based substantially on movement of the sun and an estimated high-frequency signal component, based substantially on cloud shading. An open loop controller generates a reactive power compensation signal based on at least one of the low-frequency signal component and the high-frequency signal component. The low-frequency signal component is defined by a positive portion of a sine curve that is based substantially on movement of the sun.

Abstract: A method of switching taps by an on-load tap changer includes providing at least two fingers each comprising an impedance and a mechanical switch. When first and second mechanical switches of the first and second fingers are closed, they provide a connection between the first and second impedances of the first and second fingers and a power terminal of the on-load tap changer. The on-load tap changer is triggered to shift at least one of the fingers from a first tap to a second tap of the on-load tap changer when a tap change signal is received. A solid state switch connected between the first and second impedances is switched on to commutate a current from the first finger to the second finger during the tap change operation.

Abstract: This disclosure relates to systems and methods for controlling a wind converter for a weak electrical grid. In one embodiment of the disclosure, a system for controlling the wind converter includes a wind converter connected to an electrical grid at a point of connection (POC) and operable to transfer a power to the electrical grid. The system includes a first control loop operable to calculate, based on electrical grid parameters and wind converter characteristics, a voltage reference to be generated by the wind converter. The system includes a second control loop to convert, based on the electrical grid parameters, the voltage reference into a current reference. The second loop converts the angle information of the voltage reference into a voltage at the POC. The system includes a third control to regulate, based at least on the current reference, the power transferred by the wind converter to the electrical grid.
