    DC capacitance reduction in three-phase photovoltaic inverters by using virtual impedance emulation
    (IEEE, 2019) Urtasun Erburu, Andoni; Sanchis GĆŗrpide, Pablo; Marroyo Palomo, Luis; Ingeniaritza Elektrikoa, Elektronikoaren eta Telekomunikazio Ingeniaritzaren; Institute of Smart Cities - ISC; IngenierĆ­a ElĆ©ctrica, ElectrĆ³nica y de ComunicaciĆ³n
    DC voltage regulation in grid-connected three-phase PV inverters is a fundamental requirement. In order to reduce the influence of the PV non-linear behavior and ensure stability in the whole operating range, the input capacitance in high-power inverters is currently oversized, thus increasing the converter cost. This paper proposes a control method which emulates a virtual impedance in parallel with the PV generator, making it possible to reduce the capacitance by a factor of 5. Simulation results confirm that the proposed control is stable and fast enough in the whole operating range with such a small capacitor.

    Control strategy for an integrated photovoltaic-battery system
    (IEEE, 2017) Urtasun Erburu, Andoni; Sanchis GĆŗrpide, Pablo; Marroyo Palomo, Luis; Ingeniaritza Elektrikoa eta Elektronikoa; Institute of Smart Cities - ISC; IngenierĆ­a ElĆ©ctrica y ElectrĆ³nica
    In photovoltaic-battery systems, more attention is usually paid to the MPPT control while the battery management is put aside. This paper proposes two control strategies for an integrated PV-battery system, both of them making it possible to perform MPPT or regulate the battery voltage to its maximum value in order to prevent it from overcharging. Simulation results prove the feasibility of both controls.
