An interleaved converter with maximum power point tracking
2017 International Conference on Intelligent Computing, Instrumentation and Control Technologies (ICICICT), 2017This paper, discusses a non isolated boost converter with high step up gain with an MPPT controller. The converter is meant to be used as an interface between photovoltaic panels and the utility grid. The solar panel or array without an MPPT results in wasted power and number of solar panel needed to be installed increases.

Robust fuzzy controller for photovoltaic maximum power point tracking
21st Mediterranean Conference on Control and Automation, 2013In this paper, the stability and robustness analyses of uncertain multivariable nonlinear control systems based on fuzzy logic approaches are presented. A system that comprises a Takagi-Sugeno (TS) fuzzy plant model and a fuzzy controller connected in closed-loop is first considered and second establishing fuzzy state observers.

A new maximum power point tracking system
Proceedings of IEEE Power Electronics Specialist Conference - PESC '93, 2002In power systems involving a load, a battery and a solar array, MPPT (maximum power point tracking) is a promising principle to extract the maximum amount of energy from the solar array and distribute it to the battery and loads. A digital hill-climbing control strategy combined with a bidirectional current mode power cell is presented that makes it ...

Maximum Power Point Tracking Techniques
2016An essential objective for many photovoltaic (PV) applications is represented by the so‐called maximum power point tracking (MPPT). Under uniform irradiance and ambient temperature conditions, the power versus voltage characteristic of a PV array is characterized by the presence of a unique point, termed maximum power point (MPP), where the power ...

Maximum Power Point Tracking for Photovoltaic Systems
2018 International Conference On Advances in Communication and Computing Technology (ICACCT), 2018Photovoltaic system works with highest efficiency at an operating point of maximum power on power-voltage (P-V) and current-voltage (I-V) curve. But any mismatch in a photovoltaic array leads to differences in the I-V characteristics of the PV modules. It can lead to significant energy losses known as mismatch losses.

An Improved Maximum Power Point Tracking Method
Applied Mechanics and Materials, 2013A duty ratio perturbation based on improved genetic algorithm is proposed in this paper. It can overcome some shortcomings of traditional MPPT method, and can perfectly achieve a real-time adjustment for maximum power output. A simulation model is established on Matlab, feasibility and validity of the method is verified.

A maximum power point fast-tracking system
2014 11th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2014This article refers to the maximum power point tracking system. With a few minor improvements based on the “Perturb and Observe” (P&O) algorithm, the maximum power point tracking (MPPT) system operates in higher reliability, especially in case of external radiation rapid decrease or abrupt redirection.

Adaptive Maximum Power Point Tracking Algorithm for Photovoltaic Power Systems
IEICE Transactions on Communications, 2010This paper presents an adaptive maximum power point tracking (MPPT) algorithm. The aim is to dynamically adjust the step length for updating duty ratio (or operating voltage) so as to make full utilization of the output power of photovoltaic (PV) systems, even under the rapidly changing atmospheric conditions. To this end, the average slope in terms of

Bayesian optimization for maximum power point tracking in photovoltaic power plants
2016 European Control Conference (ECC), 2016The amount of power that a photovoltaic (PV) power plant generates depends on the DC voltage that is applied to the PV panels. The relationship between this control input and the generated power is non-convex and has multiple local maxima. Moreover, since the generated power depends on time-varying environmental conditions, such as solar irradiation ...
