Abstract

This paper discusses basics of the technical design specifications, criteria, technical terms and equipment parameters required to connect Medium Scale Solar Plants (MSSPs) and Large Scale Solar Plants (LSSPs) to the electricity networks in Egypt. The MSSPs range from 500 kW up to less than 20 MW can be connected either to Medium Voltage (MV) distribution networks or to High Voltage (HV) transmission network. Successful connection of an MSSP should satisfy requirements of both the Solar Energy Grid Connection Code (SEGCC) and the Electricity Distribution Code (EDC), if connected to the distribution network, or the Grid Code (GC) if connected to the transmission network. Also, connection of a LSSP to the transmission network should satisfy the requirements of both SEGCC and the GC.
