With the increasing penetration of microgrids in distribution systems, the possibility for voltage variations increases. This paper proposes the use of a static synchronous compensator (STATCOM) fed by a DC microgrid to control the voltage of a 3-phase AC distribution grid and provide bidirectional active power transfer from the AC grid to the DC microgrid and vice versa. A simplified control is applied to this system to manage the magnitude and angle of the system voltage at the point of common coupling. With the use of a PI controller and pulse width modulation, the proposed control was able to modify the active and reactive power compensation. The control approach is characterized by its simplicity and rapid response to system changes, such as fault occurrences or load variations. The proposed control system is applied after converting the 3-phase system into a dq system to simplify the voltage regulation process. The PSCAD package is used to perform the simulation. Results demonstrate that it is possible to control STATCOM to offset reactive power and regulate grid voltage. The results validated the ability of active power transfer through the line by injecting negative and positive active power. The transfer of active and reactive power from the AC grid to the DC microgrid, and vice versa, is examined in this study following the STATCOM rating and the energy management demands.

“…Two bidirectional DC-DC converters are used to create a novel STATCOM model with a hybrid energy storage system, and the performance of both the traditional STATCOM and the STATCOM with the hybrid energy storage system is compared (Renuka and Kesavarao, 2017). In Vaidya and Chandrakar (2022), STATCOM performance for transient condition was shown improved with super-capacitor energy storage system. In Zeng (2019), Fuzzy-PI-based controller is suggested for Static Synchronous Compensator, focusing on the demands of the power distribution network on transient load voltage.…”

Power network security becomes an important issue for power system economics. A proportional integral-based static synchronous compensator in flexible AC transmission systems is generally used to enhance power network security. But, it takes more time to make the network stable and secure. A PI-controlled STATCOM with a super-capacitor as an electrical storage device and transient performance improver helps the network become stable and secure. As the PI controller depends on mathematical modeling, it may respond slowly, affecting the stability and security of the network. A fuzzy logic controller, as an intelligent controller with logical rules, can overcome the slow response problem of PI controllers. Hence, to enhance power network security, an intelligent static synchronous compensator in coordination with a super-capacitor is suggested here. A multimachine network is modeled in a MATLAB environment with severe faults near the generator, making it unstable and unsecure. The validation of the proposed combination is observed by comparing the performance of the network without STACOM, with conventional PI STATCOM, with intelligent STATCOM, and with intelligent STATCOM coordinated with a super-capacitor.

“…The outcome showed that the SSSC controller based on RBFN is superior to the PI controller. For enhancing STATCOM performance during abrupt, significant disruptions, the usage of a super-capacitor with STATCOM is suggested in [11]. The control of damping of SSSC used in power systems is examined in this [12,13].…”

Improving and maintaining the stability of a power system is a major focus of modern technology and research. However, due to financial issues, environmental concerns, and health risks associated with electric and magnetic fields, the growth of the current transmission system is constrained. Transmission line problems can be resolved by the effective use of reactive power compensation based on Flexible AC Transmission (FACT) devices. The effectiveness of these devices in regulating active and reactive powers as well as dampening oscillations in the transient phase of the power system is examined using a Static Synchronous Series Compensator (SSSC) with Artificial Neural Network (ANN) control. When compared to the traditional Proportional Integral (PI) controller, the suggested ANN controller offers better dynamic performance. For the suggested test system, this study utilized modeling and simulation using the MATLAB/Simulink software. The observations show that by using ANN in disturbed situations, power oscillations are quickly damped and power flow is enhanced.
