Impacts Of Replacing Conventional Generating Units with PV Sources in Power Plants

Meshal Abdullah Almajyul & Abdullah M. Al-Shaalan
Abstract

It has become economically feasible in the so-called energy mix to add a share of renewable energy known as photovoltaic (PV) as a percentage of the total power plant capabilities to work with conventional fossil fuel-powered generating units. The purpose of renewable energy sharing is to support and strengthen the power plant's reserve so that it can respond effi-ciently and ably to the growth of present and future loads with reduced op-erational costs. The action necessary to achieve this target is in the appro-priate location for these types of power plants, considering climatic and en-vironmental impacts such as temperature, altitude, and average solar radia-tion. Therefore, this study selected the ideal location for the power plant to be in one of the prosperous cities in the eastern region of the Kingdom. In this research, the process of comparing the addition of photovoltaic to cope with maximum loads was carried out in several cases where photovoltaic power was added from the time of sunrise to sunset with conventional gen-eration to see the effect of renewable energy before and after replacement. To accomplish this task, this research project adopted the use of one of the most popular and pronounced economic and technical simulation programs known as "System Advisor Model, SAM". SAM will assess the reliability of performance and rationalization in operation cost. The outcome will offer a sound decision-making that takes those technical, economic and perfor-mance aspects between renewable energy sources and power generating units. In this thesis, three different cases of the penetration of PV intercon-nected and disconnected with the grid have been covered; Case 1: use the PV from sunrise to sunset, it will first prioritize PV and then it will take remaining units from the grid. Case 2: deals with peak load only, it will fol-low BAU at non-peak hours, at the time of peak, it will first prioritize PV and then it will take remaining units from the grid. Case 3: use only the grid without PV. The monthly bill for Cases 1, 2 and 3 (BAU) is 82,237(SR), 90,562(SR) and 98,437(SR) respectively. As case three is BAU, that is typi-cal rate of the grid applied right now, our strategies of case 1 and case 2 cuts off the bill to 19.6% and 8.69%.
