This work proposes the development of a solar photovoltaic (PV) array powered permanent magnet synchronous motor (PMSM) driven water pumping system. Owing to intermittent nature of solar energy due to continuously varying insolation level, the presented system proposes the introduction of utility grid, which ensures a reliable and uninterrupted operation of water pump. The pump operates at a rated flow rate when integrated to the grid. The power flow from single phase utility grid is facilitated using a boost converter for power factor correction. Along with maintaining the DC link voltage, the boost converter improves the power quality performance in terms of reduced total harmonic distortion and unity power factor operation. An improved orthogonal signal generator (IOSG) is used for extraction of fundamental positive sequence component from the grid voltage. An incremental conductance algorithm is used for extracting maximum power from the PV array. A back emf based sensor-less technique is utilized for estimation of speed and position. The performance of proposed system is experimentally validated for different modes of operation during starting, steady state and varying insolation conditions using a developed laboratory prototype. The performance of the proposed system is also investigated under abnormal grid conditions. The proposed system performs satisfactorily under all operating condition confirming the power quality indices stated under IEEE- 519 standard, while drawing power from the grid.

Information Technologies are increasingly embedded into artifacts of the physical world—furniture, rooms, buildings, and urban infrastructure—making communities around-the-globe more connected and, arguably, more intelligent. However, such larger-scaled, social computing artifacts arrive with critical concerns of cost, material choice, design requirements, fabrication means, robust and safe use, power, and resistance to vandalism and the elements. Given the complexity of realizing larger-scaled, computational artifacts, conventional design methods prove inadequate and potentially costly and dangerous if researchers move too quickly to full-scale prototyping. In this paper, we present CoDAS, a hybrid methodological approach that combines elements of well-known HCI methods to effectively develop larger-scale social computing artifacts.

With the rise of transportation electrification, autonomous driving and shared mobility in urban mobility systems, and increasing penetrations of distributed energy resources and autonomous demand-side management techniques in energy systems, tremendous opportunities, as well as challenges, are emerging in the forging of a sustainable and converged urban mobility and energy future. This paper is motivated by these disruptive transformations and gives an overview of managing autonomous mobility and energy services in future smart cities. First, we propose a three-layer architecture for the convergence of future mobility and energy systems. For each layer, we give a brief overview of the disruptive transformations that directly contribute to the rise of autonomous mobility-on-demand (AMoD) systems. Second, we propose the concept of autonomous flexibility-on-demand (AFoD), as an energy service platform built directly on existing infrastructures of AMoD systems. In the vision of AFoD, autonomous electric vehicles provide charging flexibilities as a service on demand in energy systems. Third, we identify four key decisions that, if appropriately coordinated, will create a synergy between AMoD and AFoD. Finally, we discuss key challenges regarding the system-wide coordination between AMoD and AFoD.

It is vital for a city to monitor water quality in real time since the quality of water has profound effect on residents’ health. Unfortunately, it is impossible for human to monitor water’s chemical composition frequently, which is an impossibly demanding task, let alone in real time. Thus, taking advantage of a highly efficient system can be an excellent solution. In this paper, we created a system called Real-time Intelligent Monitoring System for Water Quality, which enables a city to be responsive to potential outbreak of contamination and to protect city residents. The system is capable of processing and classifying the data extracted from visual images to considerably save more money and labor. In this case, two features Fast Fourier Transform (FFT) and Color Layout Descriptor (CLD) are introduced for Saliency features and color features respectively. FFT performs well in extracting saliency features and is not computationally intensive; CLD is able to represent the color features with high effectiveness and efficiency. Additionally, this system utilizes Support Vector Machine (SVM) based on such features that needs small size of training sets, trains very fast and can classify floating rubbish and any other scenarios of water pollution with satisfying efficiency. Till now, the accuracy has reached 75%, which encourages us. While the detection performance can be further improved, the efficient features & classifiers would serve as powerful methods to automatically monitor water pollution.

In order to increase the resource utilization and reduce the idle in the process of implementing and running of cloud manufacturing, scheduling becomes a practical and critical issue. Different from most existing studies that focus on scenarios with intelligent optimization algorithms, this paper studies job scheduling of cloud manufacturing based on game theory, in which mathematical model of the public good game is put forward. Then, the problem of multi-job optimization of scheduling in cloud manufacturing is solved by BA Scale-free network and non-cooperative game. Finally, a numerical example is presented to demenstrate the feasibility of the approach.

This paper proposes an adaptive generalized predictive controller (GPC) for single phase grid connected photovoltaic (GPV) system to ensure smooth active and reactive power control. Contrary to most other linear controllers, this non-linear adaptive control strategy offers quick stabilization of system parameters under variety of stochastic changes that occur in practical photovoltaic systems such as solar insolation changes, grid frequency changes, rapid perturbations in linear/nonlinear/induction motor loads. The developed controller has capability of providing smooth steady state and dynamic responses under such disturbances. The mathematical derivation of the controller is depicted and simulation results are provided to validate the effectiveness of the proposed control strategy. The comparative analysis depicts superior performance of the proposed controller, in comparison with linear power control strategy. With linear controllers, the injected active power is prone to constant fluctuations caused by different perturbation in solar PV system, thereby, resulting in corresponding fluctuations in DC link voltages, which increase the failure rate of electrolytic capacitors and the proposed control strategy serves as possible solution to handle the stochastic changes in PV system.

Blue Energy has created a new vista of renewable and sustainable energy forms with the power of ocean. This article evaluates tidal energy as a major source of blue energy. It analyzes how tidal energy has the potential to contribute enormously towards a greener future. A few real-life examples are illustrated how the blue energy research paradigm can harness the kinetic energy of the ocean, such as triboelectric nanogenerators, tidal barrage, and tidal current turbines to replace the fossil fuels with renewable energy.

This paper addresses crucial issues, in a forum that is more qualified collectively than its author for this task. It is part of an iterative research activity that spans widely in time. It is a simple progress report. This paper is a critical overview of present and past sociotechnical change since the industrial revolution, focusing on critical processes, paradigms and practices synthetically. The idea is to explore the management of harmonious sociotechnical systems. But this will be done with an open systems approach, so the emphasis is on understanding different processes without an emphasis on logical coherence, but defining different voices and their potential impacts. Leaving the options open. Without closure, but inviting further dialogue and iterations.
