Major challenges emerging from the deregulation in power transmission system is transfer of bulk power over long distance. Transfer capability information is essential in Independent System Operator (ISO) to estimate the load forecast demand in order to ensure system security. Estimation of Available Transfer Capability (ATC) is required at regular instant to ensure that whole system is running in a reliable manner while serving wide variety of multilateral transactions. Artificial Neural Network (ANN) based ISO can estimate the online power transfer capability values for different possible power transmission in deregulated based power transmission system. Therefore, optimal utilization of ANN based estimated available power across large inter area tie lines can increase the system reliability under normal as well as contingency conditions. In power-distributed network, ATC should be estimated and enhanced for several transactions in minor duration. In this paper, case study of a 4-bus system that is estimating the transfer capability for many transactions using cascaded ANN-based technique. So, an intelligence-based approach is successfully designed in order to rise in the estimation ability as well as stabilize the performance of ISO. Simulation of 4-bus model with FACTS based Control strategies is designed for stability enhancement using MATLAB toolbox.

This paper presents with a comparative study of different shapes of MPAs with proposed rectangular MPA for X Band region, lying in Electromagnetic Spectrum, using Ansys HFSS software. This particular band is generally used in various wireless applications (Bluetooth, wi-fi and wireless LAN) and radar, and satellite communication. The proposed RMPA is designed for an operating frequency of 9 GHz, on an RT Roger/duroid 5880 material having a dielectric constant of 2.2. The return loss of -24.16 dB, a bandwidth of 425.2 MHz, VSWR of 1.07, Gain of 6.9 dB and HPBW of 80.16 degrees have been observed. On comparing with previous works, it was found that the proposed RMPA gives better results for performance parameters.

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.

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

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. The breakers with specified timing of switching are used to connect the generators for grid integration. On and off switching of the base load generator with the Grid having power generation of PV module and its impacts are analyzed with the help of specified timing.Coordinated control of the integrated power system is successfully done with the THD components within international parameters.

Boiler systems face many parametric issues due to inconsistency with grid integrated renewable power generation systems and varying load conditions. In order to achieve an efficient operation of boiler systems, varying conditions such as steam temperature, drum pressure along with drum water level must be controlled. In this paper, a nonlinear model of boiler system is simulated, with feed-water flow and fuel mass rates as the system inputs. A model-free sliding mode controller (MFSMC) is implemented with the simulated model to control the parametric uncertainties. It is observed that the implemented controller improved the performance and robustness of the system irrespective of the perturbations. With the application of the MFSM controller, the system tracks down the desired reference inputs in comparatively lesser time, resulting in smoother responses. The final simulation and results were depicted, discussed, and compared with the fuzzy control system for a better understanding of the developed phenomenon.

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.
