The Comparative Study

In this paper, we are first going to present two different renewable energy systems based on wind and photovoltaic energy in order to provide an industrial site with electrical power. This study will continue with the sizing of these systems and the assessment of their performances through a technical and economic comparison. The results show that wind energy have a low impact and a reasonable economic cost. In the second part of this paper, we are going to focus on the modelling of a Doubly Fed Induction Generator (DFIG) used in wind systems in order to compare its performances to a squirrel cage generator (SCG). Final part has been attempted to presents the comparative study of Proportional Integral (PI), Proportional Integral Derivative (PID) and fuzzy controllers. The simulations of the operation of the different generators are done with MATLAB/SIMULINK and our results are presented and analysed at the end of this work

Pv System

Renewable energy especially solar energy has become a significant part in electrical power generation with its advantage in the environmentally friendly and current trend of decrease in installation cost. The photovoltaic (PV) system on a rooftop is one of the power generating system based on renewable energy that can fit building to utilize space efficiently. This paper is analyzing the feasibility of installing a solar PV rooftop on the building using a case study building located in Bangkok, Thailand. The performance will be evaluated in term of both energy and economic perspective. The comparison with Thailand building energy code also been done to show that overall energy consumption with PV system complies with the law. The result has shown that with rooftop photovoltaic system installation, annual energy consumption in the building can be reduced significantly and it can achieve feasibility in term of economic perspective.

A 3.8 kW rooftop photovoltaic generator has been installed on an energy efficient house built at the University of Fort Hare, Alice campus, South Africa. The system, located on the north facing roof, started generating electrical power in February 2009. In addition to providing electrical energy, the photovoltaic panels also act as the building roofing material. An instrumentation and data acquisition system was installed to record the indoor and outdoor ambient temperature, indoor and outdoor relative humidity, wind speed and direction, solar irradiance, electrical energy produced by the solar panels and the household energy consumption. This paper presents the initial results of the electrical performance of the building integrated photovoltaics (BIPV) generator and energy consumption patterns in the energy efficient house.

Along with the continuous expansion of photovoltaic (PV) power generation, different capacity of grid connected PV system is gradually increased. China's first residential grid-connected PV system has interconnected successfully in QingDao and operated normally. This document analyzed electrical connected diagram of grid-connected PV system. Using power quality analyzer, the online power quality is monitored and analyzed. When PV power generation is low efficiency of operating state, harmonic current is over distortion limits. Monitoring data was simulated through electrical power standard source. To ensure power metering accuracy under harmonic, the watt-second method is proposed. Testing results show that smart electrical meter can meter accurately within 20 times harmonics.

Influence Of Temperature

All photovoltaic panel heats up when exposed to sunlight and this heating reduces the electrical power output of the same. This work presents the use of this unwanted waste heat, converting it into thermal energy directly by means of the Seebeck effect, which is the direct conversion of thermal energy into electrical energy by means of an arrangement of semiconductor materials that when exposed to temperature gradients generate electric current. In this work emphasis was placed on the influence of temperature on generation processes involved. Thus, the theoretical evaluation, it presents the mathematical models of thermoelectric and photovoltaic systems by raising the curves of voltage, current and electric power generated, and analyses the influence of temperature in each model. To obtain the simulation curves it uses MATLAB ® 5.3, taking into account the parameters of thermoelectric modules and real photovoltaic cells. In practical evaluation, a prototype was assembled containing thermoelectric module attached to the bottom of a photovoltaic panel in order to use the heat energy absorbed by the panel. The data were stored and analyzed, where we observed the influence of temperature in both systems, validating the mathematical modeling. It is the applicability of the mathematical model given the results obtained with the prototype system.

Cost Of Energy

The utilization of renewable and eco-friendly source of energy which is also referred as “Alternative Energy” is now being recognized around the world, particularly the Solar Energy. The study proposes a grid-tied photovoltaic system with net-metering that generates electricity that is linked in the electrical grid, where in excess power is sold to the utility company. The objective is to improve the cost of energy consumption of Don Honorio Ventura State University Main Campus by designing and assessing Electrical Power System that lessens the dependency on the Distribution Utility (DU). The design of the system used with respect to the roofing area per building is (3,464) 300 Watts polycrystalline PV panels, (2) uni-directional or (1) bi-directional meter for monitoring the import and export energy, and 30kW-100kW inverter to convert DC (direct current) to AC (alternating current).The computation of the savings was based on the total kWh used per month with the system installed and includes the excess or export energy that is generated from the PV solar panels. Through the assessment of the proposed system, it will surely help Don Honorio Ventura State University (DHVSU) Main Campus to save monthly electric bill and lessen the dependency of the University to the utility grid. Since DHVSU’s building are secondary metered by the Distribution Utility, there is a need to install separate PV System set-up tp meet the individual electrical requirement. The PV system will be installed via On-Grid Connection to the DU subject to the Net Metering rules and guidelines as stated by the Renewable Energy Act of 2008.
