In modern power systems due to prolific use of non-linear devices harmonics are present in the distribution system. To reduce the harmonics and source neutral current D-FACT along with a star-delta transformer and Power Filter is proposed in shunt. In this article, the three phase load has been taken from NTS Industries, which deals with FMCG products. This system includes 3 phase 3 wire system having industrial load such as mixer grinder, pulverizer, packaging machine, etc. A star-delta transformer along with three leg voltage source inverter and a capacitor used to filter out harmonics present in supply current. Power balance theory is used to control the D-FACT. A MATLAB Simulink model was created and the results were discussed.

Hybrid power generating system is well-known renewable energy equipment which is mostly intended for its consistent performance. Hence, this work develops a novel stage for power quality output by examining three DC-DC converters. This paper proposes to decrease Total Harmonic Distortion (THD) by presenting a hybrid power generation system using the integration of wind and solar power generation systems in addition to converters and full-bridge inverter. The examination is accomplished by linking converters such as SEPIC, buck-boost, Cuk converter for DC to DC level conversion. As the main objective, proportional gain, and Integral gain parameters of the PI controller, is optimized and this, to reduce the THD. For this optimization, this work develops a novel Hybrid SSO with WCO. The developed control system performance using optimization is evaluated with other existing techniques and it shows the dominance of the developed method.

“…In the early stage, the linear control method [10] ignores the uncertainty in system modeling, and its design of parameters are not robust, when system changes. To solve the shortcomings of the linear control method, adopting nonlinear control methods to design the system has become a popular research subject in recent years, such as the target holographic feedback method, fuzzy control theory [11], sliding mode variable control method [12], passive control method [13], Hamiltonian theory [14], and adaptive backstepping method [15]. Among the above control methods, the adaptive backstepping method, as a simple and effective nonlinear control method, has been widely used in designing the coordinated controller of excitation and STACOM, achieving good results [15].…”

An improved adaptive backstepping passive coordinated control strategy is proposed to deal with the uncertainty of damping coefficient and mechanical power and external disturbance on the system stability. A nonlinear coordinated controller of generator excitation and STATCOM (static synchronous compensator) is designed to improve its adaptability. The adaptive estimation laws of damping coefficient and mechanical power are designed by using I&I (immersion and invariance) adaptive control to improve the adaptive ability of the controller. Based on the backstepping recursive method, the control law of STATCOM is designed and combines the passivity theory, thus acquiring the control law of generator excitation. In the backstepping design, the derivative of the virtual control input and external disturbance are considered to be uncertain, and the nonlinear damping algorithm is introduced to reduce the “calculation explosion.” Simulation results show that the designed controller improves the stability of the power system and shows strong adaptability and robustness.
