Recent advancements in renewable energy systems, power electronics, wireless communication and Internet of Things (IoT) are combined into to a new concept known as energy harvesting IoT (EH-IoT). The new IEEE P2413 standard [1] allows the use of energy harvesting feature into the existing IoT infrastructure. The silicon solar photovoltaic (PV) cells produce energy of few milli-watts $( sim15$ mW/cm2), which can drive sensors, low-power microcontrollers and RF transmitters for a complete self-powered wireless embedded system. In this paper, we present open research issues, possible solutions, recent technologies & present state of the art of EH-IoT. We divide the research issues into four broad areas of research in EH-IoT, i.e. sensing, computations, communications, and energy harvesting. The biggest challenge in EH-IoT is designing of suitable energy harvester circuits, dynamic power management and development of energy-efficient communication protocols. This paper is useful for researchers, and design engineers for identifying the various state of the art parameters, problems and design solutions in the field of EH-IoT.

This paper focus on the design of efficient circuit and systems for low power (< 1 W) energy harvesting wireless sensor network (WSN) nodes. We investigated various topologies of solar battery charging systems. We designed a 3.6 volts battery charging circuit in MATLAB/Simulink for IoT nodes. We observed that using pulse width modulation (PWM) control techniques the battery charges up to 30% only for 500 seconds of simulation time. On another hand, using Perturb & Observation (P&O) maximum power point tracking (MPPT) techniques the battery charges up to 95 % within 200 seconds of simulation time only. Thus, as shown by our simulation results the P&O MPPT is more efficient as compared to PWM technique for battery charging of IoT nodes.s

This paper presents a DC-DC bi-directional dual active bridge (DAB) power converter, and simulating direct power control (DPC) control for the power converter. The DPC control enables it to have an enhanced dynamic response with improved dc-link voltage stability while controlling the power flow. The output voltage is controlled by the amount of power flow while the power flow depends on the phase shift ratio between primary and secondary bridge. With the DPC control presented here, the control reference is calculated from output voltage and load current, and subsequently phase shift ratio is computed, thereby controlling the power flow. The fast control over the amount power flow provides an overall enhanced performance with improved reference voltage tracking as well as robustness against input voltage fluctuation and load variation. The proposed control scheme is simulated in Matlab Simulink environment.

Nowadays, Feeder automation (FA) is the fastest growing trend among utilities to enhance the reliability of distribution networks. One of the main applications of feeder automation is automatic fault management (AFM). AFM function comprises sequential steps of fault detection, isolation and service restoration (FDISR) following a contingency in distribution networks. The allocation of automated protective devices such as circuit breakers, reclosers, remote-controlled switches, fault indicators speeds up the FDISR process. A high level of reliability is ensured by utilizing an appropriate combination of these devices but this is limited by cost constraints. Aiming to achieve an optimum reliability level, this paper presents an analytical model that incorporates protective devices, viz. reclosers (${R}$) and remote-controlled switches (RCS) at optimal positions of a radial distribution system. Cost worth analysis is utilized to develop the proposed model. Moreover, in the competitive restructuring and deregulated environment, the main aim of the utilities is to maximize their profit. The objective of the proposed model is developed from the utilities’ perspective, utilizing the profit-based optimization approach. The proposed model is tested on a 58-bus test system employing the mixed-integer non-linear programming (MINLP) optimization technique. Reliability indices have also been measured to explore the level of reliability enhancement achieved by automation. The simulation results have verified the practicality and relevance of the proposed approach in maximizing profit as well as in raising the reliability level.

High PV penetration levels have distinct characteristics which are different from conventional generation resources. That is why, it affects the steady state as well as transient stability of the systems. A significant amount of power generation may be replaced with the power generated by the distributed PV resources. Nowadays, it is in vogue to integrate renewable source of power with conventional power system. The conventional Diesel Generator with high penetration of PV based power generation is controlled by P-Q method and Fuzzy Logic control. Conventional Diesel Generator is chosen as Base load generation. Boost Converter amplifies the power output of PV module. THD component is reduced by Filter.

Stand-alone photovoltaic systems are widely used to generate electrical power in rural areas. Transients in solar radiation affect the electrical power generated by solar stand-alone photovoltaic systems. Solar stand-alone PV systems strictly require energy storage units like batteries to compensate the solar power deficiency. Batteries cannot deliver power to the system during fast transient condition. Supercapacitor has the capability to deliver power very fast. A combination of battery and supercapacitor as Hybrid Energy Storage System (HESS) is the best solution for stand-alone PV systems. A multiple converter type HESS configuration model is simulated using MATLAB/Simulink and the system performance is investigated under the different input radiation conditions.

Extensive communication has become an indispensable part of smartgrids. With the help of this connectivity, constant monitoring and control can be utilized to operate these systems in a more efficient and productive way. Increased presence of Information Technologies (IT) in power system field had large benefits such as novel applications that enable transmission lines to utilize a larger portion of its capacity, demand side management schemes that coordinate power use with respect to available energy and electric vehicle charge-discharge management solutions. Connecting all these different devices leads to implementation of Internet of Things in smart grids. However, this brings along its own challenges. So far, power systems have been operated with very limited communication and these networks have always been isolated, stand-alone systems with no connection to outside world. With the recent advancements in IT and Smartgrids, this paradigm is changing. For better coordination and control various players such as electric vehicles, smart meters, market operators and house owners are also included in these communication networks. This opens the door for cybersecurity issues that are unknown to the power system domain. A review of these challenges is presented in this paper along with solution efforts and future work.

Many emerging technologies have reported ambipolar devices. It is popularly used because of it’s controllable nature. This controllable nature allows the device to work either as n-type or p-type device. In this work, MOS based universal gates (i.e NOR and NAND gate) and ambipolar CNTFET based universal gates have been designed in a novel way. The circuits based on ambipolar CNTFET have been designed using transmission gate method. The circuit designing of MOS based universal gates require four transistors whereas ambipolar CNTFET based transistors require two transistors. The working of both the devices is verified by carrying out the simulation for both of them. The simulation results show that both waveforms are similar to each other. Thus, more number of functions can be performed by using CNTFET based logic gates thereby increasing overall system performance. All the circuit designing and simulation is carried out on HSPICE. Proposed ambipolar CNTFET based devices are simulated using Stanford CNFET model. Parameters are VDD = 1 V, Width of Channels = 381.5 nm, Pitch (S) = 20 nm, Number of CNTs (N) = 20, Diameter of CNT (DCNT) =1.5 nm. Design and simulation of universal logic gates is done at 45nm technology node.
许多新兴技术都报道了双极装置。它被广泛使用是因为它的可控性。这种可控性使得器件既可以作为n型器件工作，也可以作为p型器件工作。在这项工作中，以一种新颖的方式设计了基于MOS的通用门(即NOR和NAND门)和基于双极CNTFET的通用门。采用传输栅极法设计了基于双极CNTFET的电路。基于MOS的通用栅极电路设计需要4个晶体管，而基于双极CNTFET的晶体管则需要2个晶体管。通过对两种器件进行仿真，验证了两种器件的工作性能。仿真结果表明，两种波形基本相似。因此，使用基于CNTFET的逻辑门可以执行更多的功能，从而提高整体系统性能。所有的电路设计和仿真都是在HSPICE上进行的。采用斯坦福CNFET模型对所提出的双极性CNFET器件进行了仿真。参数为VDD = 1v, Width of Channels = 381.5 nm, Pitch (S) = 20nm, Number of CNTs (N) = 20, Diameter of CNT (DCNT) =1.5 nm。在45nm工艺节点上进行了通用逻辑门的设计与仿真。
