A power generation system (10) for generating electrical power, which may vary in response to one or more weather-varying factors (11). The system may include an array of power generators (12) subject to the weather-varying factor. A module (18) may be configured to predict over a time horizon at least one power-generating condition for the array of power generators. A controller (24) may be configured to anticipatorily adjust a control strategy regarding operation of a component and/or subsystem of the power generation system based on the predicted power-generating condition for the array of power generators over the time horizon.

A power generation system including a photovoltaic (PV) module to generate direct current (DC) power is provided. The system includes a controller to determine a maximum power point for the power generation system and a boost converter for receiving control signals from the controller to boost the power from the PV module to a threshold voltage required to inject sinusoidal currents into the grid. A DC to alternating current (AC) multilevel inverter is provided in the system to supply the power from the PV module to a power grid. The system also includes a bypass circuit to bypass the boost converter when an input voltage of the DC to AC multilevel inverter is higher than or equal to the threshold voltage.
