Hydrogen is considered a viable option for replacing fossil fuels not only because it can reduce the emissions but it also can be used as a storage option to balance the electricity grid. Current research aims the economic analysis of hydrogen production in context of a microgrid which includes 3 levels of supply, conversion and storage and primary end user. The economic feasibility of hydrogen production...
Investment models for decision making on unconventional hydrocarbon resource development in Europe must be based on realistic estimates of well productivity, gas price projections and reliable data concerning the costs of the project. In this analysis we assess the economic feasibility of three different investments projects in coal bed methane production located in three European regions: Cheshire...
Optimal power in wind farms has been a problem for constructors and managers during recent years, onshore wind farms are subject to more and more regulations and constraints. The goal is to define optimal installed capacity with maximum reliability and profits. A number of algorithms have thus been developed for the optimization of wind farm power plants. However, according to the literature, no methods...
We report the results from an economic analysis of module replacement costs in a residential c-Si photovoltaic (PV) system. Our objective is to ensure the long-term financial success of PV assets through dissemination of information regarding PV system costs and demonstrate an economic rationale to improve quality and reduce risk. These results will provide actual PV system field experience and will...
This paper presents the results that were obtained in the scope of a consultancy study developed by INESC TEC for a Portuguese distribution network company to evaluate the interest of installing storage devices and PV panels in LV installations. We conducted simulations for consumers with annual demands of 5000 kWh (Type C consumers) and 7500 kWh (Type B consumers). In general, we concluded that the...
Obsolescence is a distinctive state of both (physical) products and information, and it is commonly defined as the condition of being outdated or no longer useful. For the U.S Department of Defense (DoD), obsolescence is a serious matter that affects a host of military systems, by making it challenging to procure specific parts needed to build or repair them. For commercial engineering systems, obsolescence...
NPV (Net Present Value) is a preferred method of feasibility study to describe uncertainty of risk-sensitivity. Sensitivity analysis is an important and indispensable process. In addition to single factor sensitivity analysis, Risk-sensitivity analysis takes into account of probability distribution, control and relativity of risk factors, making the traditional sensitivity analysis more uniform and...
This paper aims at determining the feasibility of LTE-based 4G-network deployment for providing high-speed broadband access in rural India. Such connectivity is one of the important priorities of the ‘Digital India’ initiative of the Government of India, which would be a primary enabler in the fulfillment of other goals envisaged in the initiative. The assessment is done through a techno-economic...
The Renewable Energy Sources Act of 20 February 2015 changes the support for hydropower in Poland. The existing solution based on tradable renewable energy certificates will be replaced by energy auction schemes. The program promoting renewable energy sources will no longer include hydropower plants with capacity > 5MW. The RES Act also introduces restrictive mechanisms. Funding is temporary (for...
The notable features of guarantee program differing from traditional project are high degree of information asymmetry and risk uncertainty. The evaluation for credit insurance risk is the key to insurance organization. In this paper, limitations of the traditional NPV evaluation method are proposed. A credit risk pricing model of the guarantee project is put forward based on the real options, which...
Storage technologies are expected to assume an increasing relevance in the next few years, given the widespread number of available options, the possible applications and the reduction of investment costs. Therefore and apart from the well-known hydro pumping stations, the installation of storage is being considered as an increasingly viable option namely in distribution networks and also in end user...
Nigeria has a population of over 160 million, and just over 50% have electricity access. Many initiatives promote solar energy development to mitigate Nigeria's power challenges. This work shows an economic valuation of the solar photovoltaic (PV) potential in Nigeria. Assuming a 100 megawatts (MW) capacity upgrade, this paper compares distributed residential-scale and centralized utility-scale PV...
Purpose:To investigate the feasibility of utilizing texture features to classify nodule from normal thyroid tissue in Computed Tomography (CT) images. Materials and Methods: Group A (negative) includes 152 normal thyroid CT images from 55 patients healthy controls enrolled in the study. Group B (positive) includes 134 thyroid images with nodules (50 malignant, 84 benign) of 58 patients undergone thyroid...
In this paper, optimization of reservoir waterflooding process was studied using three different strategies; static optimization, and two forms of receding horizon control (RHC) which are moving-end and fixed-end RHC. MATLAB Reservoir Simulator (MRST) from SINTEF was used for reservoir simulation. The objective function to be maximized is net present value (NPV) of the venture while the control variable...
Along with the growing demand for information technology and telecommunications services, the telecommunications industry is challenged to meet the demand of availabilitiness of more qualified telecommunications services, affordable, and at cheaper price. One of the things which has become a concern in the telecommunications industry is the availability of infrastructure that seem less able to offset...
Conventional NPV analysis often reveals that the price of electricity produced by solar energy technology is significantly higher than that produced by fossil fuel using power plants. In the context of Bangladesh, this difference becomes more marked because the government of Bangladesh subsidizes the grid electricity, offering it to consumers at a cost below the cost of production. As a result, any...
The telecommunications industry has the greatest coverage among all utilities. Remote areas of the country that have no roads, grid-electricity, land line telephones or gas, still receive network coverage from one or more telecom companies. However, the Base Transceiver Systems (BTS) that these companies used in off-grid areas are dependent on on-site diesel generators, and the frequent maintenance...
This study covers the performance of a photovoltaic power generation project and an economic analysis of the project. SAM simulation tool, developed by NREL, a laboratory under DOE of USA, was used as a universal tool, and Korean weather data, electricity trading system in Korea, and Korean government incentive programs were considered. By doing so, we suggested a methodology that will be able to...
Time/cost trade-offs problems in the project management is the important role. The project scheduling with the traditional approach does not consider the difference execution time on the unit period for all activities of project. In this paper, firstly, it presents an introduction of the problem description of time-switch constraints. Then, the project scheduling with time-switch constraints under...
Telecom operators of the high growth market of Bangladesh are facing several challenges in addressing the problem of load fluctuation and load shedding in the city areas which are already integrated in the national electricity grids. It is also facing severe difficulties in the un-tapped market of rural places which are located in the off electrical grid area. The operators need to invest a lot to...
