In this paper steady state harmonic stability has been assessed in IEEE 14 bus system for fault at generator bus. It has been achieved by applying passivity based impedance model in Gauss-Seidal iteration technique. Power and load angle have been determined at normal condition as well during fault condition at generator bus. Fundamental and harmonic bus voltages have been determined both for normal...
Mean Value Engine Models (MVEM) are used to model the averaged dynamics of an automobile engine system for control and fault diagnosis. One approach to automobile fault diagnosis is to employ the use of a bank of residual generators each of which use a fault model and produces fault residues. These fault residues could then be used to detect or isolate faults using fault detection logic in the Fault...
This paper proposes a new multi-objective optimization model to minimize congestion cost, load curtailment and generation cost simultaneously to restore the equilibrium of operating point of the system under contingency. The solution algorithms of the proposed method are based on the Particle Swarm Optimization (PSO) in which load curtailment and generation cost have been optimized without breaching...
This paper presents a methodology based on Particle Swarm Optimization technique for rescheduling of generation patterns to manage congestion in contingent power networks. In deregulated systems, line congestion attract additional penalties which add on to the overall operational cost to be incurred by the Independent System Operators (ISO), apart from causing limit violations, and stability problems...
This paper proposes a systematic method for reactive loss optimization using Genetic Algorithm (GA) and load flow analysis for deregulated transmission systems. Due to nonlinear nature of power flow, tracing the loss and power flow through the mesh network becomes more complicated. In this paper, in genetic algorithm, the loss optimization using equivalent optimal power flow model has been treated...
This paper proposes a systematic method for evaluation of optimal spot prices using genetic algorithm as well as classical method. Spot pricing of electricity in a power system was proposed during early eighties considering unit generation and consumer usage as decision variables. With restructuring followed by deregulation, a number of players have started participating in the competitive power market...
The IEEE 802.16 standard specifies a mesh mode of operation which permits the setup of wireless mesh networks (WMN) with per-link QoS support. The standard specifies both distributed as well as centralized reservation schemes. Distributed scheduling is highly flexible, and enables operation of the WMN even in the absence of a central controlling instance or base station. A systematic study of strategies...
