Performance Assessment of a Realistic Egyptian Distribution Network Including PV Penetration with DSTATCOM

This paper presents the influences of integrating Distributed Static Compensators (DSTATCOMs) and Photo voltaic (PV) units in the real distribution network (Tala City) at Menoufia_Egypt. The investigation is carried out with and without DSTATCOMs at different penetration levels of PV which include 60%, 70%, 80%, and 90%. The optimal ratings and locations of the DSTATCOMs and the PV units were determined using the improved sine cosine algorism (ISCA). The ISCA is based on Levy flight distribution with adaptive operators to enhance the searching performance of the original SCA. The considered objective function includes the power losses minimization, voltage deviations minimization and voltage stability improvement. The obtained results can be concluded that inclusion of PV units can reduce the power losses and improve both of the voltage profile and stability of the system considerably with increasing the penetration levels. In addition, the performance of the studied system is significantly improved when it is connecting with both PV penetration and DSTATCOM compared with the case of PV penetration only. Moreover, the obtained results verified the effectiveness of the proposed optimization technique for assigning the allocations of the DSTATCOMs and PV units in terms of the objective function.
