Application of AAA for Optimized Placement of UPFC in Power systems Muhammad Zahid; Jinfu Chen; Yinhong Li; Ghulam Mohy-ud-din; Asad Waqar This paper suggests an innovative scheme for examining the optimized power flow problem based on optimum position and configuration setting of Unified power flow controller (UPFC) by utilizing the artificial algae algorithm (AAA) technique. Flexible AC Transmission system (FACTS) devices have the ability to provide flexibility and control for complex power transmission systems. Unified power flow controller is proficient fellow of FACTS which has the capacity to regulate power system constraints (line impedance, voltage profile and phase angle). The core aim of this research is to solve the optimal power flow problem by curtailing or removing the over-loaded of lines and the bus voltage violations created under contingency circumstances. In first round, the contingency analysis and raking process is performed while taking the transmission line loading and voltage violations as a decision parameter (DP=NOVL+NVVB). Afterwards, the proposed technique (AAA) is exercised to discover the solution of optimal power flow issue based on optimal location of UPFC with its parameters setting under the generated single contingency of line scenarios. The simulations studies are practiced on IEEE standard benchmark-5 bus system to check the performance of this novel scheme.

Comparison of High Frequency Filters for Power System Regulation Badar Ali; Muhammad Umair Alam; Zeashan Hameed Khan; Asad Waqar; Jehanzeb Ahmad This paper presents the simulation of various high frequency filters including single and double loop feedback controller based LCL filters, Zero phase filter, Savitzky-Golay filter and cascaded low-pass IIR filters utilized for power regulation from the smart grid. Power output from renewable sources comprises of DC power output. Such power needs power electronics converters to transform the output from various renewable sources of energy into alternating (AC) power having fixed frequency e.g. 50/60 Hz, so that the power can be consumed at utility level. Such conversion should not surpass the total harmonic distortion (THD) permissible limit. In order to filter out THD from such systems, various filters have been implemented in LabVIEW to compare the results.

Real-time Control of a Mobile Robot using Electrooculogram based Eye Tracking System Uzair Hassan; Hassam Mughal; Inamullah Mohsin; Zeashan Hameed Khan This paper describes a system architecture starting from the sensor design to the algorithm implementation to control a mobile robot using electrooculogram based eye tracking system. Various methods exist to control external devices with muscle movements, Electrocardiogram (ECG) or Electroencephalogram (EEG). The proposed system works with Electrooculogram (EOG) by sensing eye movement and is found beneficial for paraplegic/quadriplegic patients who can get assistance from a 2-DOF robotic arm to perform their daily tasks. This low cost design can be easily implemented on an embedded robotic platform for implementation in various domains.

Modeling and Simulation of Phasor Measurement Unit (PMU) for Early Fault Detection in Interconnected Two-Area Network Asad Waqar; Zeeshan Khurshid; Jehanzeb Ahmad; Muhammad Aamir; Muneeb Yaqoob; Imtiaz Alam The electrical power system is becoming more and more complex with the increasing demand of the electricity across the world, as the world is becoming the global village. The electrical power system must be reliable and safe enough to fulfil the energy requirements with the continuous supply of energy. The chances of power system’s blackouts and outages are increasing with its increased complexity. So, there is a need of an efficient control system to make the power system more safe, efficient and reliable. Wide Area Monitoring, Protection and Control system (WAMPAC) is becoming an emerging technology for an efficient monitoring, protection and control of power system. Phasor measurement unit (PMU) is an integrated part of wide area monitoring, protection and control (WAMPAC) system, which can be used for monitoring, protection and control of complex electrical power systems. PMU gives the synchronized phasor measurements of voltage and current and can easily monitor and control even small disturbances in power system to protect the power system from any blackouts and outages before any fault occurs. In the proposed paper a PMU model is designed in MATLAB/Simulink and then PMU is used for power system protection and the comparative analysis are done with the conventional protection technique for an interconnected two-area network power system.
