A feasibility study of electrical energy generation from municipal solid waste in Iraq: Najaf case study

In several developing countries, the electricity crisis obstructs both socio-economic and technological sustainable evolution. Also, it leads to reducing job availability due to shut down several industries or relocate to neighbouring countries to such an issue. A Najaf City is an important holy and tourist city in the middle of Iraq country. Indeed, waste management in An Najaf City needs to be reconsidered to be used as an energy source. In this article, we investigated and listed the waste quantity which produced recently (one year) respect to waste types and types of content. Data collected from the waste products for one year and are used as a key factor to study the feasibility of generating electrical energy from collected MSWs. The proposed model was simulated and tested respect to cost analysis factor of the suggested power plant by Homer pro simulation software. Results were very encouraging and competitive to the current energy production cost based on the production cost of the Kwh prospective among the conventional methods in Iraq. The proposed scenario provide proper and secure waste proposal technique with low-cost

A NEW STRUCTURE OF FIVE-LEVEL DIODE CLAMPED INVERTER WITH REDUCING ITS ELEMENTS

At the high power switching circuit's applications, when the harmonic distortion is harmful, a multi-level diode clamped inverter is useful, especially when reduced total harmonic distortion and high power are desired. But when the levels get a rise, number of semiconductors are also rising, which leads to many problems such as increasing cost, losses, installation area, and total harmonic distortion. Many researchers have tried to find solutions to these problems. In this sense, this paper focuses on: a) build a new structure of five level diode clamped inverter. b) Increase the efficiency of the inverter by reducing the number of switches. c) Reduce the total harmonic distortion. The theoretical calculation and simulation results are performed for five level diode clamped inverter by MATLAB/ SIMULINK

NINE LEVEL CURRENT SOURCE INVERTER WITH SOLAR PV

Multi-level current source using main inverter and auxiliary inductor cell is sufficient to the industrial engines because it generate high power. The present inverter consist of a basic H-bridge current source inverter working as a main inverter generates a multilevel current waveform in joining with two inductor cells connected in parallel as auxiliary circuits. The inductor cells work by generating the intermediate level of the multilevel current waveform with no additional external dc-power sources. This topology is done using Renewable energy by Depending on the solar cell as a dc source. A nine level PWM inverter configuration, with solar PV source will discuss in this paper
