SVC Placement for Voltage Profile Enhancement Using Self-Adaptive Firefly Algorithm
Get PDFStatic VAR Compensator (SVC) is one of the shunt type FACTS devices for providing reactive power support in power systems network and its placement representing the location and size has significant influence on enhancement of voltage profile. This paper presents a firefly algorithm based optimization strategy for placement of SVC in power systems with a view of minimizing voltage deviation at the load buses to enhance the load bus voltages. This method uses a self-adaptive scheme for tuning the firefly parameters. The proposed strategy is tested on three IEEE test systems. The obtained results are promising and show the effectiveness of the proposed approach
TCSC PLACEMENT FOR LOSS MINIMISATION USING SELF ADAPTIVE FIREFLY ALGORITHM
Get PDFThis paper presents the use of Self Adaptive Firefly Algorithm to identify the optimal placement of Thyristor Controlled Series Compensator (TCSC) in a power system network. The objective is to minimise the transmission loss in power system network with the placement of TCSC. To validate the proposed algorithm, simulations are performed on three IEEE test system using MATLAB software package.

Enhancing the Performance of Integrated Solar Wind and Battery System with Grid using Fuzzy Based MPPT
No full textThere is worldwide interest in renewable energy, including solar and wind power, driven by the depletion of fossil fuel and global warming. An alternative source for energy presents availability, cost, and efficiency; however, their integration into hybrid systems becomes challenging due to the intermittent nature of power output. To tackle these matters, fuzzy based Maximum Power Point Tracking (MPPT) controller has been developed. Such an MPPT controller can smooth out weather disturbances for more reliable system operations under changing input or loads conditions. Additionally, a battery connected bi-directional converter makes for effective charging and discharging processes. The grid-connected system also acts as a backup source whenever the hybrid solar-wind system together with its battery fails to meet consumer load requirements. This integration improves overall output efficiency of solar-wind hybrid systems with batteries connected to the grid. In the proposed system there are two cases with the SOC of the Battery is 9% and 50% and maintaining the AC Load power 1000W from 0Sec to 2Sec and 2400W From the 2Sec in both conditions. The efficacy of this scheme is justified through detailed simulation results obtained from using MATLAB software tools which show remarkable performance enhancements in this regard
Multi Level Inverter based Shunt Active Power Filter for connection and Power Quality Improvement of Grid Connected PV System
No full textABSTRACT: A Multi Level Inverter (MLI) based Shunt Active Power Filter(APF) is considered in this paper. Single MLI-APF is used as both Interfacing converter that processes and connects generated PV power to grid and also for improvement of power Quality of the Whole system. As Majority of the Renewable systems comprises at least two converters for these tasks, the proposed system may be treated as simple and economical in meeting the same objectives. Use of MLIs reduces stress on power electronic devices because they can be made to operate at low voltages compared to the conventional two level converters. The output voltage provided by MLIs has small voltage steps, that results in good power quality and low-harmonic components. Peak detection method of control strategy is employed in MLI-APF for power quality improvement. P&O algorithm is used for achieving Maximum Power Point Tracking of the PV generator. The proposed system is simulated using MATLAB/SIMULINK and tested for power quality improvement under the maximum Power Point Tracking of PV generator
