Abstract:

Renewable Energy has been playing an important role in the world over the last few years. Due to massive increase in prices of fossil fuels as well as alarming rate of environmental pollution, researchers and scientists are paying good number of attentions towards this energy and technology. Among various sources of renewable energy, fuel cell technology is becoming quite popular now a days. This paper presents a comprehensive analysis of fuel cell system using inverter control strategy. The results of this control strategy have been verified by the time domain simulation model developed in MATLAB/SIMULINK.

Abstract— A case study of grid connected PV system analysis is done for 500 kW grid connected solar photovoltaic (PV) system at a northern location of Bangladesh. HOMER and MATLAB Programming tools and monthly average solar radiation data from NASA is used for this study. In this paper a grid connected PV power plant is designed and simulated using HOMER software, the power plant is sized to supply Rajshahi load, the simulation results showed that a high capital cost is needed and the cost of energy is 0.27 $/kWh which is still high but with incentives and decrease of the PV panels price the system will reach a feasible cost.

ABSTRACT

This paper defines a circuit-based simulation model for a PV array in order to allow and estimate the electrical behavior of a PV array with respect changes on environmental parameter of temperature and irradiance. Taking the effect of sunlight irradiance, cell temperature, shunt resistance and ideality factor into consideration the output current and power characteristics of PV mod-el are simulated and optimized using the MATLAB/ simulink. An accurate PV array electrical model is presented based on the Shockley diode equation. A particular typical 550W solar array was used for Standalone system analyzed. Keywords : PV Modeling, Photovoltaic array, MATLAB simulink.
