In this paper, it is proposed a robust Second-Order Super-Twisting Sliding Mode Control for a Grid-connected inverter of a PV power plant. The proposed control strategy is able to maximize the energy extracted from the PV while regulating the DC-link voltage and achieving a power factor compensation and the reduction of currents harmonic distortion. Both in balanced or unbalanced condition, the grid...
In daytime operation the power converter of a photovoltaic installation is generally used below its rated power. It could then provide reactive power support to the grid. This operation is called PV-STATCOM. This work provides an evaluation of the technical cost of operating a PV-STATCOM during daytime. This technical cost is due to the need of buying active power from the grid to supply extra losses...
In order to efficiently use solar energy to generate electrical power, three-dimensional (3D) Fibonacci number photovoltaic modules (FPMs), which are designed in part based on natural plant leaf arrangements were proposed. It has been also proposed the large-scale power generation systems using multiple FPMs (hereinafter, power generation forests), and shown its power generation characteristics by...
Nowadays, thermo electrical (TE) modules are increasingly popular because their prices go down and new potential applications have emerged. This paper presents modeling, simulation, and control of the power generation of a thermoelectric generator (TEG) using Matlab/Simulink. To get the aim of maximizing the power from the TEG, an MPPT controller based on sliding mode control (SMC) was implemented...
Differential power processing (DPP) is a promising architecture to solve an issue caused by mismatch among PV modules. PV to non-isolated port bus (or PV to the virtual bus) is one of the topologies studied in DPP architecture that allows each DPP converters can achieve maximum power point tracking (MPPT) independently. The string current value does not have an effect on MPPT but relates to the power...
This paper presents an inductively coupled power transfer (ICPT) system that can transfer energy with high efficient from primary side to secondary side with variable load from 50 to 300 Ω via electromagnetic resonant coupling and output stable voltage. Main reasons for low efficiency for wide frequency deviation have been investigated. Typical compensation structures are compared in terms of efficiency,...
Power transformers are one of the critical points in the renewable energies networks for the transport and distribution of the electric energy. As a result, the diagnosis of transformers is necessary to ensure the reliability and service life. The frequency behavior of the transformer winding is generally studied using a high-frequency model to diagnose the various damages of the winding. For this...
Load converter is the second stage of multiconverter electronic power system. Under tight control, the converter acts as constant power load (CPL). The CPL has innate incremental negative resistance properties (INR). The INR influence the power quality of system. In this paper, the proposed fuzzy logic controller aims to regulate the voltage of dc-dc buck converter which is feeding the CPL and the...
In this paper a new electric power structure for solar powered unmanned aircraft system is proposed. The presented topology is a prospective improvement to both Solong and Zyphyr models. The proposed UAS model utilized Zyphry UAS by using ac bus-line instead of dc bus-line to supply the propellers. The system involves PV array, lithium sulfur based energy management system, dc bus-line, inverter,...
The purpose of this document is to give a wide-ranging comparison between different photovoltaic (PV) maximum power point tracking (MPPT) methods. The MPPTs considered in this work are perturb and observe (PO), incremental conductance (IC), sliding mode (SM), and fuzzy logic (FL) tracker. A model of MSX 60 solar module and the different MPPTs applied to a boost chopper was simulated by means of Matlab/Simulink...
This paper describes an energy management strategy for an electric vehicle (EV). The proposed EV architecture contains a pack of the batteries which presents the energy source and a pack of the supercapacitors (SC) used as power source. The pack of the batteries produces the necessary energy to move forward the vehicle while the pack of the SC produces the lacking power in acceleration and in braking...
