ISBN: 9786206163237 / Angielski / Miękka / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This Book reviews the design and evaluation of different DC-DC convertertopologies for Battery Electric Vehicles (BEVs). The design and evaluation of theseconverter topologies are presented, analyzed and compared in terms of output power,component count, switching frequency, electromagnetic interference (EMI), losses,effectiveness, reliability and cost. Thus, a bidirectional DC-DC converter with a widevoltage-gain range is desired for energy storage systems to connect a high-voltage batterywith a low voltage motor. The interleaved switched-capacitor DC-DC converter is used tointerface the...

A NOVEL PSO TECHNIQUE FOR REACTIVE POWER CONTROL IN PV GRID SYSTEM
ISBN: 9786206163398 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Grid tied solar inverters are designed to generate power at unity power factor which means that they have capability to produce active power only. The reactive power requirement of the load is catered by grid only. With the suddenly increase in the deployment of renewable based Distributed Energy Resources, reactive power drawn from the grid as compared to active power has increased considerably. The objective of this project is to present a local controller of reactive power to comply the new requirements asked by the transmission system operators despite the variation of ambient conditions...

Improve the Performance of a Grid Connected Photovoltaic System
ISBN: 9786205488324 / Angielski / Miękka / 124 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This book proposes a new control scheme of ANFIS technique to control the performance of photovoltaic system connected to grid. The main components of the studied system are solar arrays connected through a DC bus to a grid side inverter. Due to the instantaneous changes of solar irradiance and temperature, maximum power point tracking (MPPT) is integrated in the inverter control. The energy generated by the grid photovoltaic system is sent to the grid. This is accomplished through an efficient DC/AC conversion where the MPPT is integrated in the inverter to control active and reactive power...

SVM BASED 31-LEVEL MULTILEVEL CONVERTER WITH REDUCED SWITCH COUNT
ISBN: 9786204983769 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Multilevel inverters are a new family of converters for dc-ac conversion for the medium and high voltage and power applications. In this project, two new topologies for the staircase output voltage generations have been proposed with a lesser number of switch requirement. The first topology requires three dc voltage sources and ten switches to synthesize 15 levels across the load. The extension of the first topology has been proposed as the second topology, which consists of four dc voltage sources and 10 switches to achieve 31 levels at the output. Both topologies, apart from having lesser...

ANALYSIS OF A GRID CONNECTED FUEL CELL GENERATION
ISBN: 9786205491669 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Hormonic is main problem in the power system network, by using converters hormonics are generated. These hormonics effects supply system. By using passive filters to reduce the hormonics, but the usage of L, C (inductor & capacitor) passive filters have more disadvantages and large in size. Hormonic pollution is become increases due to extensive use of non-liner loads as switched mode power supply (SMPS), Uninterruptable power supply (UPS) & Power converters. These may cause the voltage drop across the network impedance and destroy the supply voltage.By using Shunt Active Power Filters (SAPF)...

POWER QUALITY IMPROVEMENT IN WECS USING FUZZY - STATCOM
ISBN: 9786204198125 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The major concern in a growing power quality is harmonics distortion which is caused by the non-linear nature of the loads. This problem has drawn much attention from utilities, users and industries. To reduce the harmonic distortion for improving the power quality of the system a custom power devices has been proposed. A static compensator (STATCOM) is implemented at distribution level for overcoming several power quality problems. In this paper, new control Technic i.e AI is proposed on shunt compensator to estimates the weight values of load currents. The control approach is based on the...

Analyse du système PV autonome à l'aide des techniques PSO et Cuckoo MPPT
ISBN: 9786205080450 / Francuski / Miękka / 104 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. La caractéristique du panneau photovoltaïque (PV) est non linéaire et dépend fortement de l'irradiation solaire et des variations de température des cellules. Pour cette raison, un algorithme de suivi du point de puissance maximale (MPPT) est essentiel pour pouvoir tirer la puissance maximale du panneau photovoltaïque et obtenir l'énergie produite maximale. L'objectif principal de la technique MPPT est de s'assurer que le panneau solaire produit la puissance maximale. Cela permet d'extraire la quantité maximale d'énergie à un moment donné. Cet article propose un concept de...

Analyse eines eigenständigen PV-Systems mit PSO- und Cuckoo-MPPT-Techniken
ISBN: 9786205080436 / Miękka / 104 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Die Charakteristik der Photovoltaik (PV)-Paneele ist nichtlinear und hängt stark von der Sonneneinstrahlung und den Temperaturschwankungen der Zellen ab. Aus diesem Grund ist ein MPPT-Algorithmus (Maximum Power Point Tracking) unerlässlich, um die Spitzenleistung aus dem Photovoltaik-Panel zu entnehmen und die maximal erzeugte Energie zu erhalten. Der Hauptzweck der MPPT-Technik besteht darin, sicherzustellen, dass das Solarmodul die maximale Leistung erzeugt. Auf diese Weise wird die maximale Energiemenge zu einem bestimmten Zeitpunkt entnommen. In diesem Papier wird ein Konzept für...
