In this study, a novel Proportional-plus-Integral (PI) controller based on gravitational search algorithm (GSA) is suggested for automatic generation control (AGC) of the two area hydro thermal power system. The significant improvement of optimal transient performance is observed with the addition of a thyristor-controlled phase shifter (TCPS) in the tie-line. In order to investigate the performance,...
This paper proposes a new innovative method to coordinate wind and thermal generation dispatch. As wind power penetrations increase in current power systems, its impact to conventional thermal unit should be investigated due to the intermittency and unpredictability of wind power generation. Development of better wind thermal coordination economic dispatch is necessary to determine the optimal dispatch...
Software testing is an important step during software development. By doing automation of software testing we can increase the robustness of software and decrease the cost of development. The automation of test data generation is done using genetic algorithm. GA analyses the fitness based on the path coverage. This paper presents a novel method for test data generation with multiple paths coverage...
This paper investigates typical behaviors like damped oscillations in fractional order (FO) dynamical systems. Such response occurs due to the presence of, what is conceived as, pseudo-damping and meta-damping in some special class of FO systems. Here, approximation of such damped oscillation in FO systems with the conventional notion of integer order damping and time constant has been carried out...
Network Intrusion Detection is the most happening field of the network security research. It is a new kind of defense technology of the network security, used as a countermeasure to preserve data integrity and system availability during an intrusion. An ideal IDS system should be capable of evolving itself to identify not only known attacks but also unknown attacks. Algorithms based on Genetic Engineering...
This paper deals with design of various controllers such as Proportional Integral Derivative (PID) controller, Internal Model Controller(IMC) and transfer function controller by using Genetic Algorithm(GA) for a non-linear liquid conical tank system. Level control of a conical tank is a complex issue because of the nonlinear nature of the tank. For each stable operating point, a First Order Process...
This paper discuss a modified Genetic Approach to Long-term Generation Maintenance Scheduling to Enhance the Reliability of the units. Maintenance scheduling establishes the outage time scheduling of units in a particular time horizon. In a monopolistic power system, maintenance scheduling is being done upon the technical requirements of power plants and preserving the grid reliability. While in power...
