Simulation of MPPT Algorithm Based Hybrid Wind-Solar-Fuel Cell Energy SystemIJMER
This paper presents a new system configuration of the front-end rectifier stage for a hybrid
wind/photovoltaic energy system. This configuration allows the two sources to supply the load
separately or simultaneously depending on the availability of the energy sources. The inherent nature of
this Cuk-SEPIC fused converter, additional input filters are not necessary to filter out high frequency

The Renewable energy is important part of power generation system due to diminution of fossils fuel. Energy production from photovoltaic (PV) is widely accepted as it is clean, available in abundance, & free of cost. This paper deals with modeling of PV array including the effects of temperature and irradiation. The DC-DC converter is used for boosting low voltage of the PV array to high DC voltage. Since the efficiency of a PV array is around 13% which is low, it is desirable to operate the module at the peak power point to improve the utilization of the PV array. A maximum power point tracker (MPPT) is used for extracting the maximum power from the solar PV array and transferring that power to the load. To track maximum power point (MPP) Perturb & Observe (P & O) algorithm is used which periodically perturbs the array voltage or current and compare PV output power with that of previous perturbation cycle which controls duty cycle of DC-DC converter. The entire system is simulated in MATLAB /SIMULINK and simulation results are presented.
Measurement and Analysis of Power in Hybrid Systemijeei-iaes
Application with renewable energy sources such as solar cell array, wind turbines, or fuel cells have increased significantly during the past decade. To obtain the clean energy, we are using the hybrid solar-wind power generation. Consumers prefer quality power from suppliers. The quality of power can be measured by using parameters such as voltage sag, harmonic and power factor. To obtain quality power we have different topologies. In our paper we present a new possible topology which improves power quality. This paper presents modeling analysis and design of a pulse width modulation voltage source inverter (PWM-VSI) to be connected between sources, which supplies energy from a hybrid solar wind energy system to the ac grid. The objective of this paper is to show that, with an adequate control, the converter not only can transfer the dc from hybrid solar wind energy system, but also can improve the power factor and quality power of electrical system. Whenever a disturbance occurs on load side, this disturbance can be minimized using open loop and closed loop control systems.

The two basic topologies of switch mode DC-DC converters (Buck and Boost) are analyzed with a view of their use in PV (photovoltaic) systems, as the photovoltaic generator exhibits non-linear characteristics due to the change in environmental condition and load variation. As the efficiency of PV panels is low it becomes mandatory to extract maximum power from the PV panel at a given period of time. Several MPPT algorithms with different types of converters are being proposed for extracting maximum power from the PV panel. It is found that the nature of load plays an important role in the choice of topology. This paper investigates the implementation issues of Incremental Conductance method with Buck and Boost Converters. Mathematical analysis and desirable steady-state operating point of the converters are derived to give satisfactory maximum power point tracking operation.

The purpose of this study is to explore the relationship among demographics, personality traits and level of confidence. The impact of this paper is twofold, one is to measure the determinants of overconfidence in employees and other is in students. This paper adopts the primary data approach, collected from employees and students through questionnaires .Two diverse populations have been selected and various statistical technique (Pearson correlation, Pearson regression, Chi-square, and Kolmogorov-Smirnov tests) are used for analysis purpose using SPSS software on a 100 sample size. Research findings shows that in employees when Openness to experience increase , overconfidence level decrease, however all remaining personality traits(conscientiousness, agreeableness, emotional stability and openness to experience) is correlated with overconfidence. In students there is no correlation between overconfidence and any of the personality traits. The regression analysis findings show that no linear relationship exists between independent and dependent variable in employees for individual personality traits except of emotional stability. Only emotional stability has a significant predictor of overconfidence among all five personality traits. However the overall personality is the significant predictor of overconfidence in employees. For students, neither individual personality traits nor overall personality has linear relationship with overconfidence.
Capacity Spectrum Method for RC Building with Cracked and Uncracked SectionIOSR Journals
one of the most widespread procedures for the assessment of building behavior, due to earthquake, is the Capacity Spectrum Method (CSM). In the scope of this procedure, capacity of the structure compares with the demands of earthquake ground motion on the structure. The capacity of the structure is represented by a nonlinear force-displacement curve, referred to as a pushover curve. The base shear forces and roof displacements are converted to equivalent spectral accelerations and spectral displacements, respectively, by means of coefficients that represent effective modal masses and modal participation factors. These spectral values define the capacity spectrum. The demands of the earthquake ground motion are represented by response spectra. A graphical construction that includes both capacity and demand spectra, results in an intersection of the two curves that estimates the performance of the structure to the earthquake. In this study, for determination of the performance levels, G+10 R.C.C. Building with cracked and uncracked section were taken. The structural Capacity of cracked and uncracked section compared with performance point value, which shows the structural capacity of building having cracked section is lesser than the uncracked section. Different modeling issues were analyzed to study the effect on Capacity of the structure with cracked and uncracked section for different position of Shear wall.
Wind-Driven SEIG Systems: A Comparison StudyCSCJournals
Wind energy is one of the fastest growing renewable energies in the world. This is because it has a much lower environmental impact than conventional energy. In addition, it is one of the lowest-priced renewable energy technologies.
Due to wind speed variation, induction generators are the best choice for such applications. However, they have poor voltage and frequency regulation against wind speed or load variations.
For its operation, the induction generator needs a reasonable amount of reactive power. In stand-alone applications, the reactive power could be supplied to the induction generator by a bank of capacitors as implemented here.
In this paper, simulation of wind turbine driven self excited induction generator (SEIG) has been carried out. Three methods of voltage and frequency regulation have been presented, simulated and analyzed.
The aim of this paper is to compare the three methods from many aspects highlighting the advantages and disadvantages of each one.

Nine Level Inverter with Boost Converter from Renewable Energy SourceIJERA Editor
A new single phase nine level multilevel inverter is proposed. The input to the proposed nine level multilevel inverter is obtained from solar panel . The solar energy obtained from the solar panel is not constant and it varies with times. In order to maintain the constant voltage obtained from the solar panel the boost converter is used to maintain the constant output voltage using MPPT ( Perturb and observe algorithm) algorithm. Then the buck boost converter output voltage is stored in the battery bank. Finally the battery energy is connected to the 9 level inverter circuits. The harmonics in the inverter is eliminated by using the fuzzy logic controller. The gate pulse for the multilevel inverter is given by the fuzzy logic controller which in turn reduces the harmonics in the inverter. Then the inverter output is connected to the grid are some application.
This paper describes the Grid connected solar photovoltaique system using DC-DC boost converter and the DC/AC inverter (VSC) to supplies electric power to the utility grid. The model contains a representation of the main components of the system that are two solar arrays of 100 kW, boost converter and the grid side inverter. The paper starts with a system description, in this part we have given a definition and a short overview of every component used in this system and they are taken separately. The PV cell model is easy, accurate, and takes external temperature and solar radiation into consideration. It also proposes a maximum power point tracking (MPPT) algorithm. The algorithm incorporated in a DC/DC converter is used to track the maximum power of PV cell. Finally, the DC/AC inverter (VSC) of three- level is used to regulate the ouput voltage of DC/DC converter and connects the PV cell to the grid. Simulation results show how a solar radiation’s change can affect the power output of any PV system, also they show the control performance and dynamic behavior of the grid connected photovoltaic system.

Analysis of Voltage and Current Variations in Hybrid Power SystemIJRST Journal
In this paper, a detailed dynamic model and simulation of a solar cell/wind turbine/fuel cell hybrid power system is Developed using a novel topology to complement each other and to alleviate the effects of environmental variations. Comparing with the nuclear energy and thermal power, the renewable energy is inexhaustible and has non-pollution Characteristics. Here Ultra-capacitors are used in power applications requiring short duration peak power. The voltage variation at the output is found to be within the acceptable range. The output fluctuations of the wind turbine varying with wind speed and the solar cell varying with both environmental temperature and sun radiation are reduced using a fuel cell. Therefore, this system can tolerate the rapid changes in load and environmental conditions, and suppress the effects of these fluctuations on the equipment side voltage. The proposed system can be used for off-grid power generation in non interconnected areas or remote isolated communities. Modeling and simulations are conducted using MATLAB/Simulink software packages to verify the effectiveness of the proposed system. The results show that the proposed hybrid power system can tolerate the rapid changes in natural conditions and suppress the effects of these fluctuations on the voltage within the acceptable range.

The lack of wind speed capacity and the emission of photons from sunlight are the problem in a hybrid system of photovoltaic (PV) panels and wind turbines. To overcome this shortcoming, the incremental conductance (IC) algorithm is applied that could control the converter work cycle and the switching of the buck boost therefore maximum efficiency of maximum power point tracking (MPPT) is reached. The operation of the PV-wind hybrid system, consisting of a 100 W PV array device and a 400 W wind subsystem, 12 V/100 Ah battery energy storage and LED, the PV-wind system requires a hybrid controller for battery charging and usage and load lamp and it’s conducted in experimental setup. The experimental has shown that an average increase in power generated was 38.8% compared to a single system of PV panels or a single wind turbine sub-system. Therefore, the potential opportunities for increasing power production in the tropics wheather could be carried out and applied with this model.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Abstract: This paper presents the implementation of a generalized photovoltaic model using Matlab Simulink
software package, which can be representative of PV cell, module, and array for easy use on simulation
platform. The proposed model is designed with a user-friendly icon and a dialog box like Simulink block
libraries. This makes the generalized PV model easily simulated and analyzed in conjunction with power
electronics for a maximum power point tracker. Taking the effect of sunlight irradiance and cell temperature
into consideration, the output current and power characteristics of PV model are simulated and optimized using
the proposed model. This enables the dynamics of PV power system to be easily simulated, analyzed, and
optimized.

I. Introduction
The global needs for polluting greenhouse gases, the rapid rise in the cost of energy and fossil fuels and
cause unavoidable energy shortages lead to a global trend to reduce renewables. Among the renewable energy
Photo-Voltaic (PV) attracts a special focus. However, relying on renewable energies associated with some
concern, as the high degree of uncertainty, unavailability during a day and fast-changing periods out of hand.
The output power fluctuation of renewable energy can cause excessive variations of voltage and
frequency of the system. In recent years, storage systems have been combined to form photovoltaic systems that
are capable of an energy reserve provided with less fluctuating output power. Electricity generation from solar
can be performed by solar cells or photovoltaic (PV).
The aim of this study experiment and simulate structure of PV study and see the effect of solar
irradiation on cell temperature, which made the output characteristics more practical PV model and the transient
analysis of power , study state regime using basic circuit equations of the PV solar cells including the effects of
solar irradiation Tested the PV model response in a DC load.
1.1 Problem statement:
1. How do wind and light intensity influence the characteristic of power generation from pv/ wind turbine ?
2. How does wind velocity and light intensity influences the efficiency between pv /wind turbine?
3. What’s the characteristic of power generation 50 w between wind and solar energy?
1.2 Objectives of Research
1. Study the best efficiency regarding to load PV and Wind turbine
2. Obtained the knowledge about the characteristics of system for small power generation between PV and
wind turbine
II. Basic Theory
2.1 Wind Power Calculations
The power output, P, from a wind turbine is given by the following expression:
1.
Where Cp is the power coefficient of the rotor varies between 0.2 and 0.5 and A is the swept area
perpendicular to the wind velocity (m2
).

2.
Where RD is the rotor diameter (m),ρ is the density of air (approximately 1.225kg/m3) and V is the
wind speed (m/s).
Moreover, the energy obtained from a wind turbine depends mainly on the velocity of wind across the turbine.
A typical wind turbine characteristic
A typical wind turbine characteristic
Where RD is the rotor diameter (m), ρ is the density of air (approximately 1.225 kg/m3) and V is the wind speed
(m/s).
Normally the wind potential is given as the specific wind power, and then the power per unit of area can be
formed by:
3.
The maximum power could be expressed as follows:
4.
Then the maximum efficiency of an ideal wind turbine will be as follows:
5.
The factor 16/27 = 0.593 is sometimes called Betz Coefficient or the Betz limit. It shows that an actual
turbine cannot extract more than 59.3% of the power in an undisturbed tube of air of the same area. In practice,
the fraction of power extracted will always be less because of mechanical imperfections. A good fraction is 35–
40% of the power in the wind under optimum conditions, although fractions as high as 50% have been claimed.
A turbine which extracts 40% of the power in wind is extracting about two-thirds of the amount that would be
extracted by an ideal turbine. This is rather good, considering the aerodynamic problems of constantly changing
wind speed and direction as well as the fractional loss due to blade surface roughness.
The efficiency of a solar cell is dependent on both the irradiance and cell temperature, i.e., both the
open-circuit voltage and fill factor decrease substantially with temperature (as the thermally excited electrons
begin to dominate the electrical properties of the semi-conductor), while the short-circuit current
increases, slightly.
The power output (in Watts) for a photovoltaic PV) panel at a given time can be expressed as
6.
Where GHI is the global horizontal irradiance (W/m2
) received on a horizontal surface, is the efficiency of
the PV and is the total area of the PV panel (m2
).

3.3 DC-DC buck converter
A boost converter is a switch mode power supply that has an output voltage higher than its input
voltage. The switching in a boost converter is done through a MOSFET or IGBT. When the switch is closed the
current flows in the first loop only, the current through the inductor grows. The switch then opens, and the
voltage across the inductor and the input combine in series to charge up the output capacitor to a higher voltage
than the input. The duty cycle of the switching signal determines the output voltage. The longer the switch is
closed, the higher the output voltage will be expected.
