The stability and dependability of the grid are of crucial importance as the integration of photovoltaic (PV) systems into electricity grids gathers momentum. Because of their bidirectional power flow and intermittent energy production, PV grid systems present a variety of issues when it comes to power quality (PQ). Effective grid management and stability are limited by the fact that conventional monitoring techniques have difficulties in providing real-time insights into harmonics, voltage stability, and transient disturbances. PV grid systems can only function at peak efficiency if the electricity being transmitted and distributed is of the best possible quality. To address the challenge of power quality monitoring in PV grid systems, this research provides an innovative strategy utilizing Internet of Things (IoT) devices and incremental conductance (IC) Maximum Power Point Tracking (MPPT). Grid operators can immediately identify deviations and problems because of the system's continuous, real-time monitoring of vital power quality metrics, made possible by the IoT. The technology provides predicted insights into power quality fluctuations by analyzing past data and patterns, which improves grid stability and resource allocation. The PV grid system is implemented in Matlab tool and PQ variations may be accurately predicted using historical data, improving grid stability and resource utilization. The study's results will aid in the efficient incorporation of renewable energy sources into the grid by assuring optimum power quality in PV grid systems.

Polymer nanocomposites have been synthesized by the covalent addition of bromide-functionalized graphene (Graphene-Br) through the single electron transfer-living radical polymerization technique (SET-LRP). Graphite functionalized with bromide for the first time via an efficient route using mild reagents has been designed to develop a graphene based radical initiator. The efficiency of sacrificial initiator (ethyl α-bromoisobutyrate) has also been compared with a graphene based initiator towards monitoring their Cu(0) mediated controlled molecular weight and morphological structures through mass spectroscopy (MOLDI-TOF) and field emission scanning electron microscopy (FE-SEM) analysis, respectively. The enhancement in thermal stability is observed for graphene-grafted-poly(methyl methacrylate) (G-g-PMMA) at 392 °C, which may be due to the influence ofthe covalent addition of graphene, whereas the sacrificial initiator used to synthesize G-graft-PMMA (S) has low thermal stability as analyzed by TGA. A significant difference is noticed on their glass transition and melting temperatures by DSC. The controlled formation and structural features of the polymer-functionalized-graphene is characterized by Raman, FT-IR, UV-Vis spectroscopy, NMR, and zeta potential measurements. The wettability measurements of the novel G-graft-PMMA on leather surface were found to be better in hydrophobic nature with a water contact angle of 109 ± 1°.

This propaganda of research implied in this progress would be arised by introducing the clustering scheme in a very poignant distribute manner. This method is very high responsive enough in order to bring up an efficient Cluster acting as the base for the designing up of the Routing protocol for the Delay Tolerant Mobile Networks. This research proposes with an approach that they are clustered into a group. The design of the kind of networks is as: 1) Distributively grouped into mobile nodes 2) The grouping up of the nodes is based on similarity pattern. 3) The similarity of the pattern is it should have a definite cluster of fixed size. The result of such implications is to - reduce the overheads based on the parameters and its constraints, secondly – balancing of the loads implied. They share the resources and perform the same. This would enhance and aim in bringing out an efficient and a enhanced routing scaled up to its standard and hence the routing is aimed to achieve a routing protocol based on exponentially Weighted moving area shortly know an as the EWMA. This one gives the details about the nodal contact it occurs and mathematical probability amongst the nodes themselves, using the weighted mean with the clusters formed. The clusters what were formed using the functions such as Sync (), Leave () and Join (). The defined number of nodes in a particular cluster need to be defined and must be greater or exceeding the optimum value the of nodes allotted for a particular cluster. Finally, some of the gateway nodes group the network information form the other gateways and determines a routing table which are all required in that particular nodes or stipulated nodes in that cluster, so as to determine the moving weighted average and perform the routing process. The results obtained from the simulations revealed the static clusters for improving the sharing of the resource capacity and decreases the memory requirement of then nodes, thus making the computations of the Routing table gets easier for access and at a faster pace too. The consistency of clusters gets improved by making the moving node to inform to its neighbours about its movement from the cluster. The use of Cluster connectivity modification packet (CCMP) is that it would bring down the traffic of the network and would calculate the computation table for shortest path route easier. From the above, one would be able to obtain greater delivery ratio values at a predominantly lesser overhead and the delay in the nodes when reaches end to end. They are poignant enough in achieving this feat when comparing the results obtained from the non – clustered algorithms.

Abstract Quadrotor, a small remote-controlled aircraft with four blades, has been a vital role to perform variety of tasks from the air. Quadrotor controller design and its modeling is a well-known field of research and is used in many civil and military applications, security purpose and filmmakers for aerial camera and videography. Most of the researchers have differently approached on quadrotor’s control and design modeling. The main aim of this paper is to model the quadrotor using state space mathematical expressions to analyse the stability of quadrotor. The state space mathematical modeling simplifies the implementation of control techniques on dynamics of quadrotor. This modeling computes the equilibrium points to analyse the stability and plant interaction of the system. The simulation results are presented using the state variables.

Abstract This paper presents the performance study of new Dual Output Quasi Z Trans DC-DC converter. The conventional Z source DC-DC converter is modified in the circuitry to generate dual output voltage which could be fed as input to the cascaded multilevel inverters feeding the renewable energy systems. This reduces source count requirement of the cascaded multilevel inverters and efficient operation is obtained by controlling the duty ratio of the converter. The proposed converter is studied for different switching frequencies and duty ratios to identify the optimum value. The circuit model of the proposed DC-DC converter is built in MATLAB /Simulink to analyze the performance and the prototype hardware is developed to validate the findings.

The mobile nodes in Mobile Ad-Hoc Network (MANET) are heterogeneous and communicate each other without centralized access point and administration. Ensuring the secure communication between the clusters is tough because of the changing wireless network environment. In recent clustering algorithm the energy minimization is not handled effectively, also due to the dynamic and distributed nature of network security in the network holds narrow research problems. Our protocol improves the efficient clustering process which reduces the number of hops to transmit the information which decreases the energy consumption. Security in terms of IDS detection and key management improved when compared with existing protocols. We consider the channel usage time allocation to minimize the interference to improve the network transmission. To illustrate the efficiency of the proposed protocol we present simulations using NS-2. Simulation results show that significant reduction in the energy and makes improvement in control packet overhead and delivery ratio as compared to existing protocols.

This paper presents the implementation of Dual voltage control in new modified Quasi Z Source inverter applied for solar water pumping systems. The new two stage inverter produces buck/boosted multi-level AC voltage with reduced circuitry, minimized inrush current and mitigated harmonics. During climatic disturbances, the proposed new topology can execute dual control over the inverter voltage and maintains a steady performance of the water pump. Operating conditions are set to have an effective smooth control over the voltage on both DC and AC side with minimized switching losses in the system. Mathematical modeling and simulations are performed in MATLAB/Simulink to analyze the effectiveness of the proposed dual control with solar water pump model. Experimentation is carried out on a prototype model to validate the performance.

Abstract This paper presents the modeling and simulation of a novel topology of quasi Z-Multilevel Inverter with stepped DC input. The proposed inverter incorporates a simple switching technique with reduced component count and is aimed at producing boosted multilevel output AC voltage. The inverter consists of two stages and the buck /boost operation is obtained by varying the shoot through period of the pulses obtained by maximum constant boost control with third harmonic injection. With all the advantages of the quasi Z-network, the proposed inverter eliminates the fly back diodes and capacitors present in a conventional Z-Multilevel Inverter. Further the stress on the devices is less which leads to reduction in component value and hence the cost. The novel stepped DC coupled Single Phase quasi Z-Multilevel Inverter is modeled and simulated in the MATLAB - SIMULINK environment and its performance is analyzed for varying input and switching conditions. The voltage and current waveforms across each stage of the inverter is analyzed and the results are presented for different levels of input.

This paper presents a novel approach for power generation from rotating machines in textile mills using externally coupled repulsive magnets and a new stepped DC coupled Quasi Z-inverter. Power is obtained as a byproduct of the effective harnessing of rotational energy with the use of repulsive magnets. This derived power is stored in a battery arrangement and is retrieved, buck/boosted, and converted to multilevel AC voltage with the new stepped DC coupled quasi Z-inverter. The proposed inverter is powered by isolated voltage sources, uses fewer switches, and produces less distortion in the resulting multilevel voltage compared to its counterpart, and thus reduces the filter requirements. The derived AC power from the system can be used for light-load applications in textile mills, thus compensating for the energy demands. Simulation of the entire proposed setup is performed in MATLAB/Simulink and the results are presented. The repulsive force produced by the magnets is assessed with K & J Magnet software. To validate the simulation, experimentation is done using rotating machines available in the laboratory. The prototype model of the stepped DC coupled quasi Z-inverter is used to study the performance of the system and the results are evaluated. The optimum modulation index is identified for different numbers of sources at the input.
