Abstract:
Solar photovoltaic can meet rising energy demand in sunny countries. Intermittent renewable energy sources require fast system dynamics. This paper describes a grid-coupled solar photovoltaic (SPV) system with an incremental conductance-based MPPT and boost converter.
Three-phase voltage source converter (VSC) with fast and robust control algorithm integrates SPV array into grid. A Zero Attracting Least Mean Square (ZA-LMS) controller generates reference grid currents. Three-phase VSC switching pulses are generated by comparing these currents with sensed grid currents.
The proposed system feeds load power demand and refines power quality by suppressing harmonics, maintaining grid current at unity power factor, and balancing loads. ZA-LMS is compared to NLMS and dq0 frame theory controllers. These controllers are compared for weight convergence, mathematical complexity, real-time computational burden, and harmonic compensation.
The grid-connected VSC prototype used as a shunt active power filter is tested with the proposed controller using dSPACE 1104. The controller’s steady-state and dynamic load performance is monitored.
