POWER MANAGEMENT SYSTEM FOR STRING SOLAR INVERTER

A system includes a maximum power point (MPP) tracker (101) coupled between a first solar panel string (112) and a DC voltage bus (Vdc), wherein the MPP tracker (101) includes a first DC/DC converter (114) and is configured to perform a maximum power point tracking (MPPT) control scheme on the first DC/DC converter (114), a power reservoir (102) coupled between a second solar panel string (122) and the DC voltage bus (Vdc), wherein the power reservoir (102) includes a second DC/DC converter (124), and an inverter (154) coupled between the DC voltage bus (Vdc) and a power grid (154), wherein the inverter is configured to operate in multiple modes including a grid-forming (GFM) mode and a grid-following (GFL) mode, and wherein in the GFM mode, the second DC/DC converter (124) is configured to regulate a voltage on the DC voltage bus (Vdc).
