Abstract

In a grid connected photovoltaic (PV) system, the maximum power will be tracked by the conventional Perturb and Observe (P&O) algorithm. It generally produces high oscillations around maximum power point, and it fails to attain extreme power under prompt environmental conditions. To overcome these issues, this work proposes a deep neural network (DNN) based Maximum Power Point tracking (MPPT) algorithm and PR controller-based SMO for PV grid-connected system. The DNN consists of many algorithms in that here we use RNN in MPPT algorithm for tracking the maximum power. The Recurrent Neural Network (RNN) hidden layer has more number of layers. The deep network weight function is optimised by meta-heuristic-based Bald Eagle Search (BES) Optimisation. The proposed tracked RNN based Maximum Power Point (MPP) is passed through the DC/DC buck-boost converter. The inverter is tuned by Proportional Resonant (PR) controller, and it has two gain parameters like a proportional and integral gain. The PR controller gain parameters are tuned by the global optimisation algorithm of Spider Monkey Optimisation (SMO) to achieve better performance. [ABSTRACT FROM AUTHOR]

Abstract

Photovoltaic systems produce energy that is not constant and is very dependent on weather conditions. Factors that can affect the output produced by solar panels always experience changes in the amount of sunlight intensity and working temperature of solar panels. To optimize the power of solar cells, Maximum Power Point (MPP) is usually used. This research design presents the implementation of Perturb and Observe algorithms for Maximum Power Point Tracker (MPPT) as a controller for solar power generators. The synchronous buck boost DC-DC converter circuit is used as a lowering voltage controller which is controlled using the P & O algorithm. The maximum power point (MPP) is the point in the VI curve or VP curve on the solar panel at which point the solar panel works in maximum efficiency that can produce the most output power. In designing the Maximum Power Point Tracking (MPPT) algorithm that is used to find and make the working points of solar panels always in the MPPT area, Perturb and Observe are needed to get the right optimization results.

Abstract

This paper discusses the efficiency of two power electronic converters connected in cascade in aim to generate the maximum power from the fuel cell and regulate the load voltage under different working conditions and load variations. The first converter is an interleaved boost proposed to minimize the fuel cell voltage ripples and determine the optimum duty cycle to generate the maximum of power. Thereafter, the control of this converter is performed through a Maximum Power Point Tracking approach. To meet the load requirements in terms of voltage regulation, a buck boost converter controlled with a Proportional Integral controller is proposed. This configuration allows generating the optimal power and regulating the load voltage at the same time. The both converters are simulated under Matlab-Simulink to validate the robustness and the efficiency of this new design. Obtained results show the robustness of the new design approach and efficiency improvement of the system.
