In the present study, standalone operation
of the solar photovoltaic system with storage is evaluated with the recently
introduced seven-level packed U-cell (PUC) multilevel inverter. Zeta converter
is used to regulate the output voltage of the photovoltaic (PV) array with the
help of the MPPT algorithm. Level-shifted modulation scheme is applied for the
PUC inverter. The standalone operation is taken into consideration keeping in
view the application/penetration of the solar PV system in remote areas. The
Ministry of New and Renewable Energy (MNRE), Government of India has set up the
plan to establish the standalone solar PV system for off-grid application in
the regions to meet the power requirement of those communities and regions that
are difficult to connect with the grid. The climatic condition in the central
and western parts of India is conductive for solar PV generation. In contrast
to the other well-known inverter topologies, such as neutral point clamped,
flying level capacitors, and cascaded H-bridge, among others, PUC inverter
requires the least number of switches and capacitors for the same output
levels. The system is modeled in the MATLAB®/Simulink using the Waaree Energies
WSM-315 modules to supply a load of 2 kW. To optimize the solar PV-based
system, incremental conductance optimization technique is used.
