Due to the continuous change in load, the frequency and tie-line power of control areas get disturbed from their scheduled value which is undesirable. Automatic Generation Control (AGC) is an essential mechanism in electric power systems which balance generated power and demand in each control area in order to maintain the system frequency at nominal value and tie-line power at its scheduled va...

Electrical energy concurrent which cannot be stored so must be utilized as soon as it is generated. Therefore it requires an effective balance of power flow within multi area power system. This paper studies about a two area system [Hydro power plant & PMSG based Wind energy conversion system] which is connected through a tie line. Due to the rapid fluctuation in the wind power it causes distur...

Automatic generation control (AGC) of a multi area power system provides power demand signals for AGC power generators to control frequency and tie-line power flow due to the large load changes or other disturbances. Occurrence of large megawatt imbalance causes large frequency deviations from its nominal value which may be a threat to secure operation of power system. To avoid such situation, ...

This Paper presents the design of decentralized automatic generation controller for an interconnected power system using PID, Genetic Algorithm (GA) and Particle Swarm Optimization (PSO). The designed controllers are tested on identical two-area interconnected power systems consisting of thermal power plants. The area interconnections between two areas are considered as (i) AC tie-line only (ii...

UNLABELLED Hidden Markov models (HMMs) are probabilistic models that are well-suited to solve many different classification problems in computation biology. StochHMM provides a command-line program and C++ library that can implement a traditional HMM from a simple text file. StochHMM provides researchers the flexibility to create higher-order emissions, integrate additional data sources and/or ...

In January 2004 the first European interplanetary spacecraft, Mars Express, was inserted successfully into a Martian orbit. The multiline scanner HRSC (High Resolution Stereo Camera) on board of Mars Express will image most of the surface of Mars in colour and stereoscopically in high resolution. The Institute of Photogrammetry and GeoInformation (IPI), University of Hannover, has created softw...

Abstract—With the rapid development of electrical power systems nowadays, stability and reliability features of the network have to be considered strongly to keep the system under normal working conditions. Because of the complexity of a large-scale or multi-area power system, load disturbances can appear randomly at any point of the network which will cause the deviations of the frequency and ...

When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...
