Abstract
A 250 kW grid-connected photovoltaic (PV) plant systems have been installed at the Ministry of Electricity in Baghdad and penetrated to the Iraqi national grid since November 2017. This is the first high power grid-connected PV system that has been installed in Iraq and it’s one of the four parts 1MW large-scale PV systems that should be completed in early of 2019. This paper presents the design and performance analysis of this system using a PVsyst software package. The performance ratio and different losses that occurred in the system are also calculated. The results show that the performance ratio is 75% using 1428 photovoltaic panels type (Sharp 175Wp) spread over an area of 1858 m². The total energy injected into the grid is (346692 kWh/year) .Based on the simulation results that developed in this paper, the practical PV grid-tied system has been implemented in Baghdad site.
Highlights
PV systems are the one of the major sources of electricity in the power systems. [1,2,3]
The values of the design parameters are, indirectly proportional and are a major challenge.For instance, the installation of many modules increases the PV plants’ energy production; on the other hand, it leads to high cost in installation and lifetime maintenance of the PV plant
The photovoltaic system package at the University of Geneva was developed over 20 years ago[6 ] as it integrates the research, sized and simulation assistance of PV systems into prefeasibility industries [7, 8, 9, 10]
Summary
PV systems are the one of the major sources of electricity in the power systems. [1,2,3]. Modeling software packages based on meteorological databases, PV modules and inverter data [5] is an appropriate instrument for productivity forecasting.There is several existing software tools for analyzing and dimensioning the PV grid-connected system. One of these software packages is a PVsyst software. A comparative study of grid-tied PV system using PVsyst software package has been detailed in [12] This scheme simulates a PV of 60 kWp with comparable parameters and Journal homepage: http://section.iaesonline.com/index.php/IJEEI/index. The energy produced has been well matched with what is presented in the outcomes of the PVsys simulation in a ten-MW network connected solar power plant[14]. The real measured energy was only a little differently at 813kWh / kWp [15] with PVsys simulated yields (823kWh / kWp)
