Abstract

Distribution Grid (DG) has become the part of main equipment of the electric power system. DG supplies power to the grid and local loads. This will require proper operation in the DG equipment when islanding to improve the system's reliability. Islanding in DG systems can cause dangerous conditions for humans and equipment. The SOGI-PLL synchronization system in DG has been tested for its ability to detect voltage and frequency disturbances quickly. Passive over/under voltage and over/under frequency detection techniques for islanding detection have weaknesses against false signal problems and inefficient validation. Passive detection techniques over the time domain of monitoring oscillations in the Rate of Change of Frequency (ROCOF) have sensitivity to grid faults and false operations during non-islanding conditions. The ROCOF in a short time compares with a threshold. Grid parameter in the form of the frequency required by ROCOF is obtained from the SOGI-PLL synchronization algorithm. The simulation of the grid tie inverter system showed improved performance, reliability, and durability due to the shared advantages of SOGI-PLL synchronization and ROCOF islanding detection protection. The optimal time obtained to detect islanding is 72 ms. While in non-islanding conditions the false signal response can be overcome.
