Abstract: The disclosure relates to technology for providing power, voltage, and/or current from a combination of DC sources. The DC sources may be photovoltaic panels. One aspect includes a stack of DC power sources (e.g., photovoltaic modules) with a DC to DC converter (e.g., power optimizer) associated with each DC power source. An output capacitor of a DC to DC converter is connected in series with its DC power source. Thus, there is a string of DC power sources and output capacitors connected in electrical series. The DC output of the system is a series connection of the DC power sources and the output capacitors. This reduces stress on the output capacitors, while allowing for efficient power generation by the DC power sources.

Abstract: This invention discloses a controller and method to reconfigure the inertia, damping and fault ride-through capability of a virtual synchronous machine (VSM). The virtual inertia is reconfigured via adding a low-pass filter to the torque (equivalently, active power) signal of the VSM and the virtual damping is reconfigured via adding a virtual damper between the VSM voltage and the output voltage sent to the PWM conversion, instead of adjusting the inertia and the damping in the swing equation. The function of the virtual damper is to scale the existing converter-side inductance or to insert the desired inductance into the VSM, which increases the damping. Moreover, the fault ride-through capability of the VSM can be reconfigured to achieve the given fault-current level via reconfiguring the damping and the inertia properly.
