Abstract: A photovoltaic system includes a photovoltaic array and a DC/AC inverter. The photovoltaic array includes an output, a plurality of photovoltaic strings each including a plurality of photovoltaic modules electrically connected in series to form an output having a first direct current voltage, and a plurality of DC/DC converters each including a first maximum power point tracking mechanism for a corresponding one of the photovoltaic strings, an input of the output of the corresponding one of the photovoltaic strings, and an output having a second direct current voltage. Each output of the DC/DC converters is electrically connected in parallel or series to form the output of the photovoltaic array having a direct current voltage. The DC/AC inverter includes a second maximum power point tracking mechanism for the photovoltaic array, an input of the output of the photovoltaic array, and an output having an alternating current voltage.

Abstract: An energy system includes renewable energy sources each including an inverter. The renewable source inverters are coupled to a distribution line in a manner wherein power combines additively. The system also includes an energy storage source including an energy storage inverter coupled to the distribution line between the point of interconnection and the renewable source inverters. Finally, a control system is structured to: (i) control a voltage at the point of interconnection by controlling a renewable source reactive power output by the renewable source inverters and an energy storage reactive power output by the energy storage inverter, and (ii) provide power ramp rate control for the renewable energy system by controlling at least one of a renewable source real power output by each of the renewable source inverters and a first energy storage real power output by the energy storage inverter.
