Introduction

The increasing demand for energy and the encouragement to utilize renewable energy sources have led to the development of Distributed Generation (DG) or small-scale power plants that are integrated into the distribution network. The study of power flows becomes an essential tool for analyzing the impact of integration on the performance of the distribution system. This article will discuss the results of the study of power flow on the 20 kV distribution network PM.6 GI Pematang Siantar, which is integrated with PLTM AEK Silau 2 and PLTMH Tonduhan, using a computer program.

Background

The integration of DG into the distribution network has become a popular solution to meet the increasing energy demands. DG can provide a reliable and efficient source of power, reducing the reliance on the transmission system and minimizing power losses. However, the integration of DG also poses challenges to the distribution system, including the impact on power flow and voltage quality. Therefore, it is essential to study the power flow on the distribution network to understand the effects of DG integration.

Condition Without DG

Without operating, the two power plants (PLTM AEK Silau 2 and PLTMH Tonduhan), one-way movement flow from GI Pematang Siantar to the load center. As a result, the voltage along the channel has decreased significantly, reaching 9.92% at the end of the channel on the bus 869 with TAP position 1 (165.75 kV) in the power transformer 2. This indicates that the distribution network is experiencing a significant voltage drop, which can affect the reliability and efficiency of the system.

Integration of DG

Conditions change drastically when both plants operate. Power flow is no longer one-way, and voltage along the channel has increased. At the end of the channel on the bus 869, the voltage reduction only reached 3.92% with the position of TAP 5 (156.75 kV) in the power transformer 2. This shows that integration with DG can help improve the quality of the voltage in the distribution network.

Further Analysis

The results of the study showed that the Aek Glau 2 PLTM was able to serve the entire active power load on the PM feeder.6. Meanwhile, PLTMH Tonduhan is only able to serve the surrounding burdens. This shows that the location and capacity of DG have a major effect on its ability to serve loads. The study also found that the integration of DG can reduce the loads on the transmission system and minimize power losses.

Impact of DG Integration

The integration of DG in the distribution network, especially in the PM.6 GI Pematang Siantar feeders, has a significant positive impact. In addition to improving voltage quality, DG also helps in reducing loads on the transmission system and reducing power loss. This study is proof that the integration of DG with careful planning can be a solution to increase the reliability and efficiency of the distribution system.

Conclusion

The study of power flow on the 20 kV distribution network PM.6 GI Pematang Siantar integrated with PLTM AEK Silau 2 and PLTMH Tonduhan has shown that the integration of DG can have a significant positive impact on the distribution system. The study found that DG can improve voltage quality, reduce loads on the transmission system, and minimize power losses. Therefore, the integration of DG with careful planning can be a solution to increase the reliability and efficiency of the distribution system.

Recommendation

To maximize the benefits of integration DG, more in-depth analysis is needed. Factors such as the optimal location DG, the appropriate DG type, and the arrangement needs to be considered comprehensively. Thus, the benefits of integration can be enjoyed optimally and the distribution system can be operated efficiently and reliably.

Future Research Directions

The study of power flow on the distribution network is an ongoing research area. Future research directions include:

Optimization of DG location: The optimal location of DG can significantly affect its ability to serve loads. Therefore, further research is needed to optimize the location of DG.
