Abstract

Electricity sector in Egypt has witnessed major developments in generation, transmission and distribution systems since 2015 due to increasing renewable energy integration, electric vehicles and electricity market reform. As a result, codes and standards have to be updated to guarantee secure and reliable operation of current and future power system. This paper suggests recommendations for updating the Egyptian electricity distribution code and solar power plants grid connection codes via a comparison among technical requirements for corresponding codes in other countries. The major similarities and differences among electricity distribution codes are clarified. Then, a detailed comparison of solar power plants connection codes is presented. The comparison includes voltage and frequency deviations, active and reactive power control, power factor control and fault ride through. Finally, proposed recommendations to update the Egyptian codes are listed
