MPPT control of photovoltaic system with temperature coefficient

Abstract

This paper proposes novel MPPT method of photovoltaic system with temperature coefficient. The conventional CV(Constant Voltage) and PO(Perturbation and Observation) methods have the weak problem about the radiation and temperature change. Thus, in this paper, in order to improve this problem, the optimal voltage and current is determined and the MPPT control is performed. The MPPT algorithm proposed in this paper analyzes the performance about radiation and temperature change and proves the validity.
