Abstract:

In the present scenario the utilization of renewable energy sources arehappening to be more popular due to more vigorous regulations in fuel economy and carbon. This paper deals with the high voltage gain interleaved boost converter for a Photo Voltaic (PV) system with a neural network based Maximum Power Point Tracking (MPPT) controller. So as to nourish the high power electrical appliances it is necessary to design high voltage gain converters. In order to meet this requirement, a three phase interleaved boost converter (IBC) which can provide high voltage gain is proposed and designed for a PV system is proposed in this paper. The interleaving technique is adapted for the proposed converter as it is able to maintain less ripple content at the converter input current there by improves the life time of PV array. It also results less voltage stresses on the power semiconductor devices which are employed for high rated PV system. Unlike conventional modelling of PV array procedure, modelling of PV array using neural network does not require involvement of any scientific definitions. Consequently they can possibly give an unrivalled strategy for inferring non-linear models than the officially settled regular procedures. In this paper a radial basis neural network trained model is employed to simulate and anticipate the MPP of a Photo Voltaic arrayutilizing an arbitrary arrangement of information gathered from a genuine photovoltaic array. In this paper Simulinkplat form of MATLAB software is employed to break down the performance of the prosed system by carrying simulation. Furthermore, it is additionally demonstrated that the MPPT from the solar PV array with the reduced harmonics is achieved through the proposed model.

Abstract:

In this, present a single-phase five-level inverter for high power applications. Whenever grid-connected system mainly focuses on maintaining less THD and less switching losses. The projected topology has a minimum number of switches as associated with existing topologies. In case, the inverter has a number of switches it produces high THD and switching loses similar more driving circuits are required. So in this proposed topology consider less number switches. Similarly, SPWM control technique is utilized to control the inverter. In SPWM techniques, level shifter modulation is implemented for proposed topology. With the help of Matlab software, the proposed topology is simulated and get results.

Abstract:

RNS has the ability toperform subtraction, addition independently with carryfree propagation. The structure of RNS requires two types of conversion: Forward Conversion and Reverse Conversion. To convert binary to residues, forward conversion is used whereas to convert residues to binary reverse conversion is used. Special moduli set and arbitrary moduli set are the two types of forward conversions. (2n-1) mod adder is one the important block used to get the special moduli set type of forward conversion. This paper consists of mod (2n-1) adders for the forward conversion technique and comparison of designs at both Schematic level and RTL level. The schematic level designs provides low power than RTL design whereas the delay is reduced in RTL than Schematic design. The designs have been simulated for RTL using NC Launch - Encounter tool standard 90nm Technology.The designs have been simulated using CMOS 90nm virtuoso tool in cadence for schematic designs.

Abstract:

Microgrid protection is one of the challenging tasks, now a day microgrids placed an important role. In general, some conventional protective devices (Circuit breaker and relays, etc.) are there for the protection of microgrids. These conventional protective devices having some drawbacks, they are during abnormal conditions continuity of supply is not possible and it permits up to three cycles of error currents into the network. To overcome that disadvantages Superconducting Fault Current Limiter (Resistive type) is used. Under standard conditions R-SFCL offers small resistance then it acted as a superconductor, under fault circumstances it offers more resistance then error currents are minimized. It allows only one cycle of fault current into the system and continuity of supply is possible.

Abstract:

AC- DC or DC-DC converters are today entirely dominated by switched-mode power converters, SMPCs. The industry today, in the race of meeting customers’ demands, is looking at packaging more and more power in lesser and lesser volumes. Hence the power supply designers are always engaged in devising new topologies and techniques to achieve power densities efficiently. Soft switching is one such technique which aids the designers in finding a solution to increase power densities by raising the switching frequency. The present paper proposes the least complicated soft-switching technique in low power flyback converters. Flyback converter in the power range of 150W is taken as a study piece, and soft switching is demonstrated without adding any extra hardware and control overhead. The obtained results are compared with a hard switched CCM flyback converter. Practical working models are built, tested, and evaluated to display the efficacy of the proposed scheme.

Abstract:

The approach of symmetrical components of power flow analysis is the very salient technique to inspect the bus power flows in a 3-phase unbalanced and balanced power system network during the healthy or unhealthy case operation. There are various traditional programs available in the literature,which solve the single-phase equivalent power system models for power flow analysis. The main aim of this paper is to conduct a positive sequence power flow analysis on a balanced 3- phase IEEE 57 bus test case matlab Simulink model by using the Load Flow Tool. The present power system model consists of 7 thermal energy systems, each system configured with IEEE type-1 Excitation, Steam turbine, and Governor. The simulation study is useful for finding the bus voltages, active power losses and reactive power losses in the lines. However, there is an empirical analysis conducted with present results with the test case. There is a voltage improvement is observed at the buses with the present model. The efficiency of the model and convergence criteria perceive with the simulation results report. The simulink model is also useful for the steadystate analysis of power system network as well as the power flow analysis of the network with various grid connected renewable energy sources.

Abstract:

Active Power factor corrected AC-DC converters in the power range of 500 watts and above are mostly accomplished in a two-stage process. The front end is non-isolated boost regulator working in CCM and the second stage is a DC-DC converter with isolation. This process is less efficient, complex and consumes more area. The front end PFC in CCM is a major source of EMI requiring heavy line filters to meet the international interface specifications. A novel single-stage AC-DC converter for the output power of 1KW is proposed here, which has many advantages such as Single active switch, completely soft switched and isolated. The new configuration is fabricated and tested for all the parameters. A near unity PF is achieved and the worst case efficiency is recorded to be 94%. All the test data are presented.

Abstract:

In this paper a three phase dc to ac converter with embedded chopper(echopper) is proposed for bidirectional interfacing applications, aimed at constant and stable irregular DC-bus, which can vary the battery voltage in wide range of applications. Compare to conventional dual stage conversion of DC to AC e-chopper requires less power for processing and consumes less power losses by using modest carrier built- pulse width modulation (CB-PWM) scheme through proposed zero structure addition. Implementation of proposed PWM scheme needs a small amount of power for processing of e-chopper, hence maximum control is managed through DC-AC conversion. So the overall transformation efficiency of DC-AC arrangement has been improved via e-chopper, by minimizing the power processing thus implies overall efficiency of the system. This paper analyzes the physical characteristics, ideologies and operation of the proposed Bidirectional inverter as well as its Pulse Width Modulation scheme in detail.

Abstract:

The most promising source of renewable energy is solar photovoltaic (SPV) generation. These SPV modules facing issues with varying environs as well as Partial shading conditions (PSC) of cells in the modules. Normally, for varying PSC of single SPV module maximum power point tracking (MPPT) techniques is quite adequate to overcome these issues. But in practice, SPV modules are interconnected and formed as SPV arrays and these are used for SPV generation in large scale applications. So these arrays are facing the PSC which results in multiple peaks in the P-V curves. This paper investigates the behaviour of three different structures of SPV arrays which gives rise to multiple peaks due to PSC. In this paper, SunPower SPR-X20- 250W-BLK module data is used to form SPV array and it is examined under PSC conditions with different irradiance (G) and temperatures (T) values. The electrical performance characteristics under PSC with three different structures of SPV array is obtained using Matlab/Simulink and are examined to get a clear idea to choose which style of connection is better for PSC.

Abstract:

This paper discusses about ELD Problem is modelled by non-convex constrained based cost function. This paper discusses the noncovex cost function based ELD problem. Actually, these problems are not solvable using a convex optimization techniques. Normally convex-conventional techniques are not solvable to ELD problems. So there is a need for using a meta-heuristic optimization methods. So in order to solve the non-convex cost function problems, a new meta-heuristic optimization techniques are required. Out of all optimization techniques, Oppositional Teaching and Learning Based Optimization (OTLBO) is introduced to solve the ELD problems and which will give better promising results. In this paper, OTLBO algorithm is used to solve the load dispatch problems economically. to solutions economically with valve point loading effect. In this paper, Oppositional Teaching and Learning Based Optimization (OTLBO) compares with other standard standard algorithms like TLBO and lambda iteration method. The OTLBO feasibility and effectiveness is demonstrated on 6, 10, and 14 units test systems along with the other optimization algorithms. The Comparison results enhance the global best solution for economic load dispatch solutions.

Abstract:

This voltage multiplier increases the converter voltage to a significant level by a PWM switching technique. The duty cycle in the PWM controller controls the step-up converter operation and maintains the required output level. An inverter inverts the boost converter DC output to AC power and fed to the induction motor (IM). The operation of the IM is mainly based on the suitable choice of converter-inverter system. Inverter operation is controlled by a PWM switching technique. This paper mainly deals with the photovoltaic (PV) integration of Voltage Doubler converter and an inverter (DC-AC) fed IM drive for water pumping applications. Solar energy from the renewable resource is the primary source for this paper because of its availability. The electrical equivalent of available solar power is 77000 TW, and PV technology is adapting to convert solar energy into electrical. In renewable energy applications, a new high step-up converter is using to boost up the input variable low-voltage. Converter doubles the input voltage by using a voltage multiplier circuit. The proposed model is designed in MATLAB and the output waveforms are plotted.
