Analysis of the Use of D-Statcom and SVC to Power Losses and Voltage Profiles in the Distribution System Connected to Distributed Generation (DG)

Introduction

In the world of electricity, power loss and voltage profile are crucial parameters that must be considered in the distribution network. Maintenance of these two aspects is vital to avoid adverse losses for both producers and consumers. One way to improve distribution network performance is through the granting of reactive power compensation using the Flexible AC Transmission System (FACTS) device, such as Distribution Static Compensator (D-Statcom) and Static Var Compensator (SVC).

The Importance of Power Loss and Voltage Profile in Distribution Networks

Power loss and voltage profile are essential parameters in the distribution network. Power loss refers to the energy lost during transmission and distribution, while voltage profile refers to the variation in voltage levels across the network. Both parameters have a significant impact on the efficiency and reliability of the distribution system. Excessive power loss can lead to reduced energy efficiency, increased operational costs, and decreased consumer satisfaction. Similarly, voltage profile issues can cause equipment damage, reduce the lifespan of electrical equipment, and compromise the overall reliability of the distribution system.

The Role of D-Statcom and SVC in Reactive Power Compensation

D-Statcom and SVC are two types of FACTS devices used for reactive power compensation. D-Statcom uses modern technology to provide a faster response in overcoming reactive power fluctuations, making it more effective in maintaining voltage stability in the distribution network. SVC, on the other hand, has the advantage of controlling reactive power over a longer period of time, contributing to the stability and efficiency of the system.

Study Objectives and Methodology

This study aims to analyze the impact of the use of D-Statcom and SVC on the weakest bus specified through the Fast Voltage Stability Index (FVSI) value. The study was conducted on the IEEE 13 bus distribution network system connected to Distributed Generation (DG). The simulation results show that the optimal location for the installation of D-Statcom and SVC is located on bus 671, with a capacity of 3 MVAR each.

Simulation Results and Analysis

The study of power flows conducted shows that before the installation of D-Statcom and SVC, the IEEE 13 bus distribution network suffered an active power loss of 0.0805 MW, a reactive power loss of 0.0936 MVAR, and the minimum voltage profile reached 0.9607 PU. After the SVC installation, there was an improvement with a loss of active power of 0.1%, a reactive power loss of 0.05%, and an increase in the minimum voltage profile to 0.9618 PU. Then, after the installation of D-Statcom, a more significant improvement was recorded, with a loss of active power losses of 0.23%, reactive power losses of 0.11%, and the minimum voltage profile increased to 0.9623 PU.

Additional Analysis and Explanation

The use of D-Statcom and SVC has a significant impact on the performance of the distribution system. D-Statcom's ability to provide a faster response in overcoming reactive power fluctuations makes it more effective in maintaining voltage stability in the distribution network. SVC's advantage in controlling reactive power over a longer period of time contributes to the stability and efficiency of the system.

The Importance of FACTS Technology in Distribution Systems Connected to DG

In the context of the use of distributed generation, the device FACTS becomes very relevant, given the variations in energy production originating from renewable energy sources. Both, D-Statcom and SVC, can adapt to changes in load and fluctuating production. This will lead to saving operational costs and increasing consumer satisfaction through the provision of more reliable energy.

Conclusion
