Abstract
This paper presents improvement tests based in a feedback-current controller designed to Tracking Maximum Power Point in photovoltaic system (MPPT-PV). Previously, a version was developed exhibiting results satisfactory in simulation and through of a low cost prototype. Now, using a sophisticated physical model of solar cell available in PSIM program is shown other cases, considering variations both irradiation and temperature to evaluate successfully the controller. The results show that its system is suitable under dynamical changing atmospheric conditions operating with effectiveness acceptable.
Highlights
A MPPT (Maximum Power Point Tracking) controller is most effective solution used to maximize the power extracted from PV modules under atmospheric conditions [1]-[5]
A special feedback-current controller designed to operate as a MPPT system is developed [10], which is a circuit highly efficient, simple, rugged, low cost design, and ideal for applications in isolated locations in the less developed countries
This paper presents improvement tests using Physical Model (PSIM) [11], a simulation program which allows additional verifications, specially focused to evaluate of the MPPT behavior
Summary
A MPPT (Maximum Power Point Tracking) controller is most effective solution used to maximize the power extracted from PV modules under atmospheric conditions [1]-[5]. A special feedback-current controller designed to operate as a MPPT system is developed [10], which is a circuit highly efficient, simple, rugged, low cost design, and ideal for applications in isolated locations in the less developed countries. This paper presents improvement tests using PSIM [11], a simulation program which allows additional verifications, specially focused to evaluate of the MPPT behavior. (2016) Upgrading Tests Using PSIM Tool of MPPT-PV Feedback-Current Controller. Fernández Hernández under some perturbations not considered previously [10]: insolation changes, temperature variations and dynamical response of the controller. New simulation tests prove that the proposed controller can achieve effective, precise and fast response, being a part of the essential characteristics of a MPPT unit, when is oriented to be used in an isolated place
