Assessment of PV Penetration Impacts on Assiut International Airport Long Distribution Feeder Using Multi-Objective Performance Index

Abstract

Photovoltaic (PV) systems play a very important role in the generation of sustainable and environmentally electric energy. The main objective of this paper is to: i) introduce a proposal for providing an electric power supply based on PV systems to improve the power quality, ii) assess the impacts of PV penetration on Assiut international airport (ATZ) distribution grid, which is fed by 11 kV long transmission line of 22 km length. First, the PV system sizing process is achieved using the PVSYST software. Then, the impacts of PV penetration on the distribution feeder are assessed using Electrical Transient Analyzer Program (ETAP) version 19.0.1. Impacts of PV penetration on the distribution feeder are assessed by the concept of multi-objective performance index (MPI). The results show that the consumed electrical energy from the main grid declined from 3.226 MW to 2.748 MW. Also, the active and reactive power losses are decreased by 10.2% and 15.6%, respectively providing a considerable decrease for the losses induced by the long transmission line of 22 km. In terms of MPI and its proposed indices, the results point to the satisfaction range of the indices results within a safe limit. The MPI improved from 0.4 to 0.63 approaching to unity that is the optimum value and providing an enhancement for the grid by 57% after PV penetration.
