Abstract:
1. A photovoltaic system with a photovoltaic current (Ipv), a photovoltaic voltage (Vpv), a photovoltaic power (Ppv), a control frequency (fs) and an output power (Po), wherein there is a derivative (dIpv/dVpv) of Ipv with respect to Vpv, comprising: a power-increment-aided incremental-conductance (PI-INC) maximum power point tracking (MPPT) controller guided by a control chart, wherein the control chart includes: an Ipv-Vpv curve and a Ppv-Vpv curve; a dIpv/dVpv-Vpv curve; a dIpv/dVpv-fs curve; and and a Po-fs curve.
