Abstract
This paper proposes a 17 MW photovoltaic (PV) power plant in the Al Jaghbub Oasis that is located in the south of Libya, where solar energy is available. This oasis is connected to the Libyan network through a medium-voltage transmission line, and its local load is small. This transmission line experiences a voltage rise, which increases in magnitude of voltage. This project explains how to take advantage of the implementation of solar energy to cover domestic loads and export excess power to the grid as well as to reduce the voltage in the 66 kV network. Thus, application of PV generators has an effect on voltage profile. Also, the design of the PV power plant and the control system to control active power and power factor are described in this paper. The controlled PV power plant connected to the 66KV network has been successfully modeled, implemented, and tested using a power system simulation program, PSCAD.
