A reliable control method for a DC-AC single-phase inverter with an output LC-filter is presented in this research. For three-phase systems, the control method employing a dq-synchronous frame is frequently employed, but it is rather difficult for single-phase systems. In order to make the suggested controller easy to use in a dq-synchronous frame, a fake…
Voltage stability is a critical concern in power systems, especially in unstable grids with high levels of renewable energy penetration and peak load switching. Digital Voltage Stabilizers (DVS) are a compromising technology for improving voltage stability in these grids. DVS uses real-time monitoring and control to adjust the position of the regulator on the secondary…
This work describes a robust control approach for calculating controller gain. For a three-phase dc-ac inverter with an output LC filter, robust control techniques were used. The control rule is given in a synchronous dq frame and was developed using a discrete-time state space design approach. It integrates the tracking error and uses state feedback.…
The initial cell search process played an important role during the operation of the downlink signal estimation operation between the user equipment (UE) and the base station. Because cell search procedures are necessary, which entail synchronizing with time and frequency as well as determining the cell ID before obtaining information about the system and other…
The focusing position and pump beam spot sizes are critical factors in determining the performance of the end-pumped Nd:YAG laser. Understanding and optimizing these parameters can help researchers and engineers enhance the laser’s efficiency, leading to improved applications in various fields. To investigate this, we conducted a series of experiments by varying the focusing position…
Economic dispatch (ED) is one of the main problems addressed in the study of power supplying load demand. There are many proposals for this optimal fuel cost in power generators. In this paper, ‘Ant Lion Optimization Algorithm’ (ALO) is used for solving this ED problem. ALO Algorithm is one of the new Meta-Heuristic methods. Ant…
This paper proposes using Linear Matrix Inequality (LMI) for robust controller design in a three-phase grid-connected inverter (GCI). The controller, applied to a three-phase dc-ac inverter, integrates state feedback and error correction within the dq-rotational frame to eliminate offset errors. An LMI-based optimization minimizes settling time despite uncertainties in the L-filter (expressed as resistance and…
In this project, the Proportional Integral (PI), Integral Proportional (IP), and Proportional Integral Derivative (PID) algorithms are used for controlling the speed of the DC motor. These controllers were developed using MATLAB/SIMULINK for better outcomes. Controllers are made for closed-loop systems. PID tuning is used in this instance to design P-I, I-P, and PID…
Economic load dispatch (ELD) is the process of generating real and reactive power from the generator to meet the power demand of the power system while minimizing fuel costs as the generator input. To solve the ELD problem with maintaining voltage stability, the Improved Particle Swarm Optimization (IPSO) method was proposed in this paper. The…
In the standalone operation mode of the microgrid, the system is significantly weakened due to a lack of inertia support from the conventional synchronous generator. Hence, in-vestigation of the impact of photovoltaic (PV) power variation and load transition on the standalone microgrid system both stability and quality are essential. In this paper, a mi-crogrid system…
