With ICT pervading everyday objects and infrastructures, the ‘Future Internet’ is envisioned to undergo a radical transformation from how we know it today (a mere communication highway) into a vast hybrid network seamlessly integrating knowledge, people and machines into techno-social ecosystems whose behaviour transcends the boundaries of today’s engineering science. As the internet of things continues to grow, billions and trillions of data bytes need to be moved, stored and shared. The energy thus consumed and the climate impact of data centers are increasing dramatically, thereby becoming significant contributors to global warming and climate change. As reported recently, the combined electricity consumption of the world’s data centers has already exceeded that of some of the world's top ten economies. In the ensuing process of integrating traditional and renewable energy, monitoring and managing various energy sources, and processing and transferring technological information through various channels, IT will undoubtedly play an ever-increasing and central role. Several technologies are currently racing to production to meet this challenge, from ‘smart dust’ to hybrid networks capable of controlling the emergence of dependable and reliable green and energy-efficient ecosystems – which we generically term the ‘energy web’ – calling for major paradigm shifts highly disruptive of the ways the energy sector functions today.

The EAI Transactions on Energy Web are positioned at the forefront of these efforts and provide a forum for the most forward-looking, state-of-the-art research bringing together the cross section of IT and Energy communities. The journal will publish original works reporting on prominent advances that challenge traditional thinking.

investigated to conserve energy and reduce emissions. Transmission lines (TLs) play a serious role in transmitting
generated electricity to different distribution units in facility engineering. The transmission lines function as a link between
shoppers and a Power Station. Faults usually occur within the transmission when positioned in an open field. Quick
identification and sick line faults square measures required for the conventional operation of the plant. A way like distinct
moving ridge rework (DWT) and (EMD) is used to locate and identify faults to resolve this disruption. DWT is used to
break down fault transients, as a result of which the info can be collected at the same time in each time and frequency
domain. EMD decomposes the TLs voltage into Intrinsic Mode operation (IMFs). Four varieties of fault signals are square
measurements produced by the grid-connected facility. Line faults square measure induced MATLAB/Simulink

smaller financial commitments, and they use renewable resources; hence are more environmentally friendly with lower
carbon footprints. Also, microgrids require fewer technical skills to operate, rely more on automation, and are isolated
from grid disturbance or outage. Traditionally, microgrids have been employed in remote locations that cannot be
connected to the central power grid and serve critical infrastructure. Due to the recent advancements in technology,
microgrids have become more accessible and economically feasible. Microgrids can be employed in organizations that
intend to lower their energy cost. The paper explains a detailed literature review and the contributions of the authors in
Interconnected Microgrids. Also, the data taken from the survey was used in the transfer function blocks in simulation.
The simulation of the interconnected microgrids comprising Thermal, solar, and wind turbine systems is formulated on
MATLAB. The frequency error and ACE are reduced to zero in a quick time by using a fuzzy PID controller. Also, the
paper aims at achieving one of the most important United Nations Sustainability Development Goals (UNSDGs),
Affordable and Clean Energy (UNSDG- 7).

This paper presents a way that can help the authorities speed up the pothole detection process by the use of a camera-enabled Unmanned Aerial Vehicle drone. The system is further enabled with a geo-tag and reports the presence of a pothole to the central database which is accessible by the relevant authorities and the common road users. The potholes are located on an
open-source map, through which the users using the road can take caution. This increases public safety and helps the concerned authorities take action faster. The model is trained with YOLOv3 algorithm to even detect potholes filled with water, and distinguish potholes from dark road patches, and etc. The results show good accuracy of 85% in detecting the potholes with a low false-negative and false-positive rate.

With the help of scaling techniques, it can integrate more features into the chip for optimization of actual circuit space. But the main drawback of
this scaling is short channel effects. And also as the technology shrinks, the leakage power plays a crucial role compared to dynamic power consumption. To avoid leakage power, the proposed design technology is used for the optimization of power and for avoiding short channel effects. To further reduce power consumption, the CMOS technology is replaced with transmission gates in switched-capacitor converter circuits and GDI Technique while generating clock signals in the circuit for operations.

The latter includes information and measurement systems (IMS) of fire alarm systems, which are part of the fire detectors. Fire alarms (FA) are triggered by the appearance of primary signs of fire, transmitting a signal to the fire alarm control and indicating equipment (FACIE) through the appropriate loop. The FACIE processes these signals and forms commands for further actions, for example, sending alarm signals (sound and/or light) by fire alarms to warn people of danger, transmitting alarm notifications to the fire station and/or centralized fire monitoring console, as well as enabling and/or disabling certain equipment or engineering systems (including fire protection systems). Fire alarm loops (FAL) are electrical circuits that connect the output links of the FA, which include auxiliary remote radio elements and conductors, and are intended not only for issuing notifications about their status to the FACIE, but also for supplying power to these detectors. The reliability of the functioning of such IMS directly depends on the correct choice, according to the appropriate methods, of the nominal value of auxiliary hinged elements of loops, problems that arise during the use of equipment from different manufacturers.

Neural Network (GA-HNN) is presented to reduce recursive blackouts. Reformulation of generation dispatch for a power grid
comprising biomass, hydro, solar, waste to energy plant, wind and geothermal have been carried out. Each of these sources
requires a mathematical formulation that considers security limits and intermittency of renewables. Modelling and simulation
was conducted on MATLAB. According to the simulation results obtained, it can be deduced that GA-HNN based optimal
generation dispatch of Ethiopian power system is a key solution in connection to developments needed in the adoption and
realization of smarter grids as it concurrently increases its security level and decreases total generation cost. Generally, reducing the number of recursive blackouts, decreasing generation cost, allocating optimal generation level, and reducing computation time are prospects of employing GA-HNN based OGD.

FACTS is a popular solution to utilize this existing power transmission system by using series compensation by means of the series capacitor to enhance the power transmission capacity as well as voltage stability. This paper explores the utilization of series capacitor applying to the power grid of Eastern part of Bangladesh. For doing this we have considered the analytical calculation of 10% to 85% compensation of that power line. As a result, we have observed that the power transfer capacity has been enhanced about 37 times and it also improve the voltage stability, when the compensation ration is 85%. We consider our calculation mathematically and represent the load curve and voltage profile by plotting in Matlab.

An accurate prediction of wind speed is more important for wind energy systems, but it is difficult due to its uncertain nature. This paper presents three artificial neural networks namely, Back Propagation Network (BPN), Radial Basis Function (RBF) and Nonlinear AutoRegressive model process with eXogenous inputs (NARX) with Mutual Information (MI) feature selection for wind speed prediction. The MI feature selection identifies the significant features and reduces the complexity of wind speed prediction model without loss of information content. The performance of prediction model is evaluated in terms of Root Mean Square Error (RMSE) and Mean Absolute Error (MAE). The results show that the performance of all three neural network models are highly satisfied. Moreover, NARX model with mutual information feature selection is more accurate in dealing with wind speed prediction.

This growing in using of PV technique hinge on the electrical load profile that required to be covered and the rate of the electricity that can be generated from the areas where the solar cells to be installed. The production of PV systems is based on the fuel which is represented by the solar radiation. In this study, an algorithm has been proposed to optimize the solar tilt angle based on MATLAB software (m-file) in order to maximize the PV generation. Monthly and annually optimal tilt angles are suggested for different case studies those are: Najaf, California and New Delhi. Also, the estimation of solar radiation for each month is calculated according to their optimal tilt angles. The obtained results indicate that the yearly gain of solar radiation from orientation solar panels is approximately 18% for Najaf city and a high gain values for winter months with very small energy gains for summery months, and so on for other case studies. This proposed algorithm is general program and can be applied for any site on the earth by changing the latitude and longitude of the desired area.

Ubiquitous systems can help to increase the capacity through an efficient usage of existing parking slots. In this case, cars are recognized during the entrance phases in order to guide them automatically to a proper slot for space-saving reasons. Prior to this step, it is necessary to determine the size of vehicles. In this work, we analyze different methods for vehicle classification and size measurement using the existing hardware of car parks. Computer vision techniques are applied for extracting information out of video streams of existing security cameras. For streams with lower resolution, a method is introduced figuring out width and height of a car with the help of reference objects. For streams with a higher resolution, a second approach is applied using face recognition algorithms and a training database in order to classify car types. Our evaluation of a real-life scenario at a major German airport showed a small error deviation of just a few centimeters for the fist method. For the type classification approach, an applicable accuracy of over 80 percent with up to 100 percent in certain cases have been achieved. Given these results, the performed methods show high potentials for a suitable determination of vehicles based on installed security cameras.
