Design, simulation and financial analysis of a fixed array commercial PV system in the city of Abu Dhabi-UAE

In urban planning, governments usually hold the decision-making power to shape not only city landscapes but also people's lives with the promoted goals of social welfare. Although states expect their own version of ideal scenarios in mind when carrying out infrastructural developments, after competition, people in reality have their own ways of perceiving and utilizing state-made infrastructures and urban transportation, sometimes in alignment with government plan, and sometimes at odds with it. Abu Dhabi is one of the cities in the world in which the government planned out the whole city and created urban infrastructure from scratch, including the city bus system. Although the Abu Dhabi public buses started operating in 2008, car dependency is still high and many residents consider public buses to be inefficient and time consuming and only used by certain immigrant working population.

The City

In many cities that have experienced rapid growth like Abu Dhabi, urban microclimate scenarios evolve rapidly as well and it is important to study the urban thermal dynamics continuously. The Local Climate Zone (LCZ) classification considers factors related to the physical properties like surface cover and surface structure of the city which allow to analyze urban heat flows. Abu Dhabi city is rapidly expanding and is characterized by highly heterogeneous types of built forms that comprise mainly of old mid-rise and modern high-rise buildings with varied degrees of vegetation cover in different parts of the city. The fact that it is a coastal city in a desert environment makes it quite unique. This paper presents an approach of studying urban heat flows in such heterogeneous setup. First, the city is classified into local climate zones using images acquired by Landsat Satellite. Numerical simulations are performed in the designated LCZs using a computational fluid dynamics software, Envi-met. The results of Envi-met are calibrated and validated using in-situ measurements across all four seasons. The calibrated models are then applied to study entire Abu Dhabi island across different seasons. The results indicate a clear presence of urban heat island (UHI) effect when averaged over the full day which is varying in different zones. The zones with high vegetation do not show large average UHI effect whereas the effect is significant in densely built zones. The study also validates previous observations on the inversion of UHI effect during the day and in terms of diurnal response.

Solar Pv System

Solar energy has become a matter of global attention in the past few years. This paper explores the use and benefit of solar concentrators in the solar photovoltaic (PV) systems. First, a short literature review of previous research on the usage of solar concentrators in improving solar PV system performance and reducing the cost of implementation is presented. This is followed by an overview of SolarBrane, an example of a Building Integrated photovoltaic (BIPV) system which uses an optical concentrator in the solar PV design. An optimised design of the SolarBrane is also discussed afterwards. A financial benefit study is conducted to compare the average return of investment of using the optimised SolarBrane and traditional solar PV installed in Malaysia’s environment. SolarBrane has proven to be a good alternative to achieve costeffective solar PV system. The financial analysis simulated under the new Malaysian Feed–In Tariff scheme indicates that the optimised SolarBrane could potentially reduce the initial cost of implementation by 40% and generate higher return, close to 20%, when compared to traditional solar PV systems.

This paper describes the design of a 14 kW grid-tied photovoltaic system for powering a hydrogen generation and refueling station that is being constructed at the Las Vegas Valley Water District. The fixed array layout is determined by considering the available space, aesthetics and impact of shading on annual energy production. Computer simulations using PV-DesignPro software and area hourly solar radiation data are conducted to simulate the energy flow into and out of the electric utility grid for different profiles of hydrogen use. Stand-alone system operation is also simulated to estimate the maximum amount of hydrogen that can be produced under limited storage.

Significance This is the latest offensive after a series of wins by GNA-aligned groups in western Libya, repelling Haftar’s offensive to take control of the capital, Tripoli and the whole country. Turkey’s official intervention in the conflict since December 2019 in support of the GNA has now fundamentally shifted the balance of power. Impacts Haftar's losses could endanger his position with his external allies in Abu Dhabi and Cairo. The threat of mass reprisals by GNA-aligned forces will make Tarhuna groups fight fiercely -- even if the LNA withdraws from the city. If the GNA eliminates the LNA’s threat in the west, it may look to retake control of the oil crescent.

Faecal Sludge

Many sub-Saharan African towns currently face a “faecal sludge crisis”, because large amounts of faecal sludge from unsewered toilets (pit latrines, septic tanks etc.) are dumped into the environment. This causes public health problems and environmental degradation. The objective of this research was to investigate how faecal sludge management (FSM) can be made an integrated part of a sustainable ecological sanitation (ecosan) approach, with an emphasis on financial sustainability. Kumasi, a city in Ghana, West Africa, with 1.48 million inhabitants was chosen as a case study. Our research shows that the FSM of the city can be independent of donors’ financial support and thus financially sustainable if the potential revenue in both households and farmers is realised. This potential revenue was evaluated by (i) analysing the relevant functional groups and their relationships, (ii) a Capacity-to-Pay approach for households whereby they would spend up to 0.5% of their income on the toilet pit/septic tank emptying service (including a cross-subsidy approach), and (iii) on the farmers’ Willingness-To-Pay for compost (treated faecal sludge) based on a price of US$ 1.4 per 50 kg bag of compost. This additional revenue, which should be allocated to the System Manager (Kumasi Metropolitan Assembly) in the proposed financial scheme, was estimated to be US$ 57,000 per month from households and US$ 18,000 per month from farmers (based on 6300 m3/month of faecal sludge collected in Kumasi and a simplified financial analysis of the system).
