ADAPTIVE PI CONTROL OF STATCOM FOR VOLTAGE REGULATION PDF

Abstract: STATCOM can provide fast and efficient reactive power support to maintain power system voltage stability. This paper proposes a fuzzy control model. Since the adjustment is autonomous, this gives the plug-and-play capability for STATCOM operation. In the simulation test, the adaptive PI control shows. Abstract— To Maintain Voltage Regulation A STATCOM. Provides The Fast And Efficient Reactive Power. In order to understand various STATCOM control.

However, these previous works obtain the PI gains via a trial-and-error approach or extensive studies with a tradeoff of performance and applicability. Hence, control parameters for the optimal performance at a given operating point may not be effective at a different operating point.

This paper proposes a new control model based on adaptive PI control, which can self-adjust the control gains during a disturbance such that the performance always matches a adaptivee response, regardless of the change of operating condition. In the simulation test, the adaptive PI control shows consistent excellence under various operating conditions, such as different initial control gains, different load levels, change of transmission network, consecutive disturbances, and a severe disturbance.

Adaptive PI Control of STATCOM for Voltage Regulation

In contrast, the conventional STATCOM control with tuned, fixed PI gains usually perform fine in the original system, but may not perform as efficient as the proposed control method when there is a change of system conditions.

Voltage Regulation by Adaptive PI Control of STATCOM

However, these previous works obtain the PI gains via a trialand- error approach or extensive studies with a tradeoff of performance and applicability.

Hence, control parameters for the optimal performance at a given operating point may not always be effective at a different operating point.

To address the challenge, this paper proposes a tor control model based on adaptive PI control, which can self-adjust the control regluation dynamically during disturbances so that the performance always matches a desired response, regardless of the change of operating condition. The results show that the adaptive PI control gives consistently excellent performance under various operating conditions, such as different initial control gains, different load levels, change of the transmission network, consecutive disturbances, and a severe disturbance.

In contrast, the conventional STATCOM control with fixed PI gains has acceptable performance in the original system, but may not perform as efficient as the proposed control method when there is a change of system conditions.

Also, the extension to other power system control problems can be explored. Your email address will not be published. Figure 1 Studied system Fig. Leave a Reply Cancel reply Your email address will not be published.
