Remote areas in UAE are still fully powered by diesel generators. The rapid rise in the prices of petroleum products and environmental concerns have led to demand for hybrid renewable energy generators. Advances in renewable energy technologies impart further impetus to techno-economic power production. Protecting the landscape and demography of th...

Limited access to electricity in remote rural areas is one of the most challenging issues in Iraq. The utilization of renewable energy technologies for off-grid electricity generation has become an attractive option for minimizing the concerns of global warming and continuous depletion of fossil fuels. This work aims to study the techno-economic an...

In recent years, the concept of hybrid energy systems (HESs) is drawing more attention for electrification of isolated or energy-deficient areas. When optimally designed, HESs prove to be more reliable and economical than single energy source systems. This study examines the feasibility of a combined dispatch (CD) control strategy for a photovoltai...

Off-grid hybrid energy systems (HESs) have become more cost-effective and reliable than single-source systems for the electrification of rural areas. This paper presents a techno-economic and environmental analysis of different hybrid systems to supply electricity to a typical Iraqi rural village. The HOMER software is utilized for the optimization...

The activity of partial discharge (PD) is one of the major causes of failure of high voltage transformers. Partial discharge detection is usually used as a preventive technique to avoid large-scale losses in the power system. Suitable and reliable methods to detect and localize PD in equipment winding insulation, such as in a transformer, are still...

In this study, two novel algorithms are developed: the quasi-oppositional smell agent optimization (QOBL-SAO) and its levy flight variation (LFQOBL-SAO), and their performance is compared to that of the conventional smell agent optimization (SAO). Two investigations were carried out. First, the capabilities of the novel algorithms were tested in so...

Due to photovoltaic (PV) technology advantages as a clean, secure, and pollution-free energy source, PV power plants installation have shown an essential role in the energy sector. Nevertheless, the PV power plant cost of energy must be competitive when compared to traditional energy sources. Therefore, numerous studies are continuously being condu...

One of most important things now is to create smart street and smart lighting system to save enormous electrical energy. Especially Iraq is suffering shortage of electrical energy generation up to 45%. Because of this, Iraq needs to save a lot of electrical energy in the entire country so as to meet the electrical demand and reduce the large amount...

Photovoltaic (PV) modules have been becoming well-spread recently as alternative clean energy sources to traditional energy sources due to their efficiency and sustainability benefits. This paper applied various water temperatures and artificial dust levels to a couple of monocrystalline PV modules under outdoor conditions to observe their performa...

The selection of an appropriate dispatch strategy is considered as a major concern when designing hybrid energy system (HES) since it has large effects on the stability, reliability, environmental and economic performance of the system. The cycle charging (CC) strategy is a default dispatch strategy in HOMER software. However, the main drawback of...

Hybrid energy systems (HESs) consisting of both conventional and renewable energy sources can help to drastically reduce fossil fuel utilization and greenhouse gas emissions. The optimal design of HESs requires a suitable control strategy to realize the design, technical, economic, and environmental objectives. The aim of this study is to investiga...

HOMER software is a powerful tool for modeling and optimization of hybrid energy system (HES). The main two default control strategies in HOMER are load following (LF) and cycle charging (CC) strategies. In these strategies, the decision to use the generator or battery at each time step is made based on the lowest-cost choice. Therefore, these stra...

Temperature and solar radiation have large effects on the performance of photovoltaic (PV) systems. PV cell temperature is related to the ambient temperature, while the solar radiation incident on PV surface depends on the slope and azimuth of the PV panels. Furthermore, ground reflectance (albedo) affects the solar radiation incident on the PV sur...

Iraq has massive potential for electricity generation from solar energy. Because the country currently suffers from daily electricity shortages, a grid-connected PV system is an unsuitable option since the PV cannot serve the load during the electricity blackouts. This paper aims to analyze the techno-economic and environmental feasibility of a sol...

The There are many factors influencing the performance of photovoltaic (PV) systems. Among these factors, temperature and solar radiation are two major parameters that have a large effect on the efficiency of PV systems. The cell temperature of PV panels is related to the ambient temperature while the solar radiation incident on the surface of the...

Depletion of fossil fuel reserves, unpredictable fluctuation of diesel prices, and global warming issue have motivated numerous countries to produce new policies for energy that engorge the utilization of alternative energy sources. Renewable energy resources like solar, hydro, and wind are clean and have potency to be more widely used. Integration...

Function signal generator has a wide range of applications in electronic measurement and teaching. Yet, many of the trading tests signal generators are bulky and expensive. Furthermore, many types of them are in a fixed operating mode with limited utilized signals. The aim of this research paper is to design a multi-functional, multi-waveform with...

Current power systems create environmental effects because of the using of fossil fuels, specially coal, since CO2 is released to the atmosphere. Contrary to conventional energy sources, renewable energy sources produce a clean energy which is in general free of pollution, environmentally sustainable and technologically efficient. There is an incre...

A reliable electrical energy supply is a prerequisite for improving the standard economic and quality of life levels in a country. As is the case in many countries, Iraq is home to a collection of remote villages. Since it is uneconomical to connect these villages to the existing grid, the installation of standalone electrical power generators has...

A reliable electrical energy supply is a prerequisite for improving the standard economic and quality of life levels in a country. As is the case in many countries, it is uneconomical to connect these villages to the existing grid, the installation of stand-alone electrical power generators has become common practice. As a result, diesel stand-alon...
