Performance Analysis of a Grid-Connected Upgraded Metallurgical Grade Silicon Photovoltaic System

Performance Analysis of a Grid-Connected Upgraded Metallurgical Grade Silicon Photovoltaic System

Because of their low cost, photovoltaic (PV) cells made from upgraded metallurgical grade silicon (UMG-Si) are a promising alternative to conventional solar grade silicon-based PV cells. This study investigates the outdoor performance of a 1.26 kW grid-connected UMG-Si PV system over five years, reporting the energy yields and performance ratio and estimating the long-term performance degradati...

Dynamic Modelling of a Compressed Air Energy Storage System in a Grid Connected Photovoltaic Plant

The use of photovoltaic (PV) cells in domestic and industrial applications has grown rapidly through the recent years. Constructing PV plants is a very smart measure to produce free electricity in large scales, especially in the countries with higher solar irradiation potential. On the other hand, compressed air energy storage (CAES) has already been proposed to be employed for energy storage a...

Control System Design and Fault-Ride-through Performance Analysis of Grid-Connected Microturbine Generation System

In recent years, microturbines as one the distributed generation sources have widly used. This paper investigates the control structure of the microturbine and analyzes its performance in grid-connected mode. In this way, first, the mechanical model of the microturbine is presented. Then, the electrical structure of the microturbine, consisting  of permanent magnet synchronous generator (PMSG) ...

Control of Harmonics and Performance Analysis of a Grid Connected Photovoltaic System

World energy consumption is increasing substantially .Growing scarcity and rising prices of fossil fuels may lead to economic instability. Continuously increasing energy consumption will overloads the distribution grids as well as the power stations, therefore having a negative impact on power availability, security and quality. One of the solutions for overcoming this is use of renewable energ...
