Abstract

In this article, authors implemented the hybrid system for continuous power distribution to fluctuating load demands. It contains a photovoltaic solar panel and wind turbine as renewable energy source, supercapacitor with a power convertor and a three-phase variation load. The combination of battery storage unit with super capacitor in hybrid system is proposed to solve many problems by its different technical features based on the system energy storage unit. Supercapacitor overcome the demerits of cells (batteries) such as charging and discharging cycles, critical charging current, reduced temperature coefficient and helps in extension of the electrical grid. Direct adjustment or indirect methods, such as to separate the energy storage unit output power adjustment, protect the hybrid energy storage components of the system. The optimal performance and desired control strategy is presented by MATLAB Simulink.

Abstract

This paper deals with the analysis of a Quasi -Z source inverter with a simple boost control strategy presented for non conventional energy applications. The aim objectives of this paper are to increase the boost factor and reduced input ripple current. The switching pulses for the inverter are generated by using simple boost control strategy; the main advantage of this control technique is to reduce the inductor ripple and inductor value. Non conventional energy sources dependence upon the external climatic conditions, the input voltage and currents are varying accordingly, which affects the performance of conventional inverters with voltage and current fed inverter. To overcome the disadvantages of conventional inverters like Voltage Source Inverter (VSI), Current Source Inverter (CSI), and voltage fed inverter called as Z Source Inverter (ZSI)/quasi-Z source inverters (QZSI) are used. It can perform several functions such as Alternating Current (AC) to Direct Current (DC), DC to AC, DC to DC. It works as Buck Boost DC to AC without use of DC to DC conversion, by utilizing the shoot through states. QZSI is obtaining from original ZSI. Simulation of simple boost control of QZSI is carried out in the MATLAB/Simulink environment.

Abstract

Classic maximum power point tracking algorithms ensure correct operation in uniform light conditions. However, when a Photovoltaic (PV) array is under Partial Shading Conditions (PSC), several local maxima appear on the photovoltaic characteristic curve of the photovoltaic array, which is due to the use of bypass diodes to avoid the effect of hot spots. The appearance of these multiple peaks in the characteristics of the PV array makes it difficult to track under these conditions and requires the integration of a more efficient power management system that is able to distinguish between local and global peaks to harvest the maximum possible energy and therefore increase the efficiency of the entire system. In addition to implement global maximum power point tracking strategies, the mismatch loss associated with the shading effect can be further reduced by using alternative PV array configurations. This paper provides an overview of Maximum Power Tracking (MPPT) using Artificial Neural Networks (ANN).
