Abstract

Solar energy is currently being developed, one of the technologies being photovoltaic (PV) panels. The PV can generate electrical energy by absorbing sunlight through an extraordinary process. Due to the increased demand for electrical energy, the DC-DC converter is one component of the PV system that is installed to meet these energy needs. The Maximum Power Point Tracker (MPPT) control system is then mounted to monitor the maximum power point close to the characteristics of the PV frame. This paper addressed the subject matter of the MPPT Incremental Conductance (IC) Algorithm using a comparative study of the effects of the Buckboost and Zeta Converter Circuit Modeling. Both DC-DC converters are designed for a 1 kWp PV network that has been proposed to use a grid-connected PV network with an output voltage above 360 V. Simulations are conducted under Standard Test Condition with various irradiance conditions ranging from 100 to 1000 W/m2 and 25C temperatures. The
result of the modeling shows that the output of the solar panels is consistent with the power characteristics of the changes in irradiance and temperature. The zeta converter has the best performance with 94 % efficiency and high response time compared to the buckboost converter with only 90% efficiency. Nonetheless, all circuits with MPPT control IC algorithms are still used to maintain output at full efficiency.
