This paper presents an optimal allocation method for distributed generations (DGs) for market-based power systems considering congestion relief and voltage stability. The sensitivities of the overloaded lines to bus injections are considered for ranking the load buses. The new generations for these load buses are then computed by genetic algorithm (GA) considering to maximize the system performance...
As the distribution grid increasingly integrate rooftop solar PV, their power generation outputs are uncertain due to the solar radiation, panel temperature, passing cloud, and v-i characteristic operating level. Therefore, PV grid connected system would require a supplementary source to ensure more stable PV power generation, particularly during cloudy periods. In this paper, the battery storage...
Out of hundreds of microalgal strains reported, only very few of them are capable for production of high content of lipid. Therefore, the key technical challenges include identifying the strains with the highest growth rates and oil contents with adequate composition, which were the main aims of this work. From 147 Microalgae screened for high biomass and oil productivity, the Nannochloropsis sp....
In this paper we will study the performance of a Silicon Photovoltaic (PV) with different tilt angle arrangement in State of Kuwait (latitude 30° N). In the study the PV system is installed facing South, collecting maximum solar radiation at noon, and their angles are from 0° to 90° respectively, during full year at the Solstice and Equinox periods, aiming for the best output power towards vertical...
Photosynthetically active radiation (PAR) is a portion of solar radiation in the wavelength band of 400–700 nm providing energy for photosynthesis of plants. In this work, we proposed to estimate PAR from atmospheric parameters using an artificial neural network (ANN). The input data of the ANN are solar zenith angle (θz), cloud index derived from MTSAT-1R satellite together with precipitable water...
The objectives of this research were to design and test a suitable set of drip irrigation powered by solar cell for sugarcane field in dry rainfed and no electricity area. This design was based on 1.5 m of sugarcane row width and 40 m of drip tape length. A drip tape was laid on soil surface and it could be rotated to other sugarcane plots. The components of the set were a 1 m3 water tank installed...
Solar photovoltaic electricity is more expensive compared with conventional electricity at retail level. As a result, general public members do not find the solar PV electricity an attractive option to use for generating a portion of their electricity need. To promote PV electricity utilization and to make it more attractive, Governments of some countries like Germany, Japan, USA, Australia, and etc...
The purpose of this study is to explore the short-term effects of air pollution on the frequency of cardiovascular and respiratory diseases in urban area of Sfax (Tunisia). We insist also on the influence of meteorological factors on the frequency of these diseases. Using the Autoregressive Distributed Lag (ARDL) cointegration procedure introduced by Pesaran. M and Shin. Y (1999) and extended by Pesaran...
This research is to study the characteristics of cellular premixed flames that are investigated on ceramic porous board with CH4/C2H6/CO2 mixtures (main compositions of natural gas in Thailand). Cellular flames are the phenomena caused by intrinsic instability induced by thermal expansion and of diffusive thermal instability due to preferential diffusion of mass versus heat. In lean combustion premixed...
The Bioeconomy strategy fosters the integration of the agricultural, chemical, pulp and paper industries and the energy sector for obtaining sustainable bio-based materials and bioenergy. Basically all industrial sectors relying on biomass are facing economic burdens by resource competition. The cascade and coupled use stand as potential solutions for cross-sectoral cooperations to mutually enhance...
Food waste contains a substantially large amount of organic matter, which can be digested anaerobically to produce biogas. In this present study, biogas yield of food waste was evaluated in a laboratory scale anaerobic batch reactor. The effect of solid concentrations (5, 7.5, 10, 12.5 and 15%) on the yield of biogas was investigated at mesophilic temperature condition for a hydraulic retention time...
Solar irradiance models are commonly used for determining incident solar radiation on a surface. However, such models are seldom capable of capturing the full temporal dynamics of solar irradiance or accounting effectively for spatial variability. We present a model which is used in combination with high resolution LIDAR city surface models to simulate solar irradiance across the urban surface throughout...
This paper was aimed to study the thin-layer drying of osmotic dehydration of Thai cherry tomato (Queen cherry tomato) and to investigate the thin-layer drying kinetics of osmotic dehydration of cherry tomato by using a convective air dryer. The osmotic dehydration of cherry tomato was dried under controlled conditions of temperature of 50°C, 60°C and 70°C and relative humidity (rh) of the drying...
Research on urban resilience is increasingly receiving attention by both policy makers and researchers. In the on-going debate, the focus is usually placed on economic and infrastructural aspects. Human factors, such as collective behavior change in the face of environmental threats or in the aftermath of extreme events, have up to present not been investigated extensively. In this research, we aim...
This paper primarily focuses on formulating an agent based model covering the financial and transactional aspects of deregulated Indian power markets which goes in hand with the legal system of the regulator. It proposes an information system which helps the agents of a power market to take decisions in making better bids and participate in the day ahead markets. A price forecasting engine based on...
This work elucidates the effects of pre-treatment of sewage sludge for enhancement of biogas production to generate green energy and reduction of carbon footprint in STPs. Microwave pre-treatment has been adopted for this study. Experiment works have been designed and conducted to examine the effectiveness on the disintegration of sewage sludge and biogas production of continuous and intermittent...
Megacities in India are historically the major economic growth centers and Kolkata is the oldest and the most densely populated mega city. An assessment of sustainable development challenges and possible green growth strategies give rise to some interesting insights that are generalisable as well. Sustainable development priority assessment for Kolkata district brings forth the issues which go beyond...
