In this study the geometrical optimization of monolithically integrated solar cells into serially connected solar modules is reported. Based on the experimental determination of electrodes0 sheet and intermittent contact resistances. the overall series resistance of individual solar cells and interconnected solar modules is calculated. Taking a constant photocurrent generation density …

This paper presents a 24 hour ahead microgrid power planning using the approach of unit commitment by dynamic programming. The studied system comprises twelve PVbased active generators with embedded storage and three micro gas turbines. Based on the prediction of the energy available from the PV generator. the storage availability. …

Decentralized electricity generation by renewable energy sources offer greater security of supply for consumers while respecting the environment. But the random nature of these sources requires us to develop sizing rules and use these systems to exploit them. This paper proposes an integrated PV wind hybrid system optimization model. which …

This paper presents a method to operate a grid connected hybrid system. The hybrid system composed of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC) is considered. The PV array normally uses a maximum power point tracking (MPPT) technique to continuously deliver the highest power to …

This paper proposes a method of modeling and simulation of photovoltaic arrays. The main objective is to find the parameters of the nonlinear I–V equation by adjusting the curve at three points: open circuit. maximum power. and short circuit. Given these three points. which are provided by all commercial array …

We present a non-traditional CMOS inverter composed a junctionless (JL) NMOSFET and an N+ -N–P transistor which with simple process and high integration density in this paper. In the non-traditional CMOS inverter the JL NMOSFET serves as driver and the N–P transistor serves as load. respectively. Based on the measurement …

The battery energy storage station (BESS) is the current and typical means of smoothing wind- or solar-power generation fluctuations. Such BESS-based hybrid power systems require a suitable control strategy that can effectively regulate power output levels and battery state of charge (SOC). This paper presents the results of a wind …

Today. given the population growth in the world. we witness development of industry sector. particularly building construction industry. so as on the one side. we are confronted with fuel consumption increase and consequently uncontrolled production of buildings’ environmental contaminators and on the other side. non-observance of the standards and non-insulation …

This book has two purposes. The first is to examine the electromagnetic theory behind many of the calculations relevant to the design of high voltage overhead transmission lines. These include electromagnetic propagation on multiple parallel wires above the earth and their associated fields. electrostatic fields near more complicated geometries. limitations …

Power Systems Modelling and Fault Analysis: Theory and Practice. Second Edition focuses on the important core areas and technical skills required for practicing electrical power engineers. Providing a comprehensive and practical treatment of the modeling of electrical power systems. the book offers students and professionals the theory and practice of …
