Power factor correction and load balancing in three-phase distribution systems
(1998)
This paper deals with the different methods for compensating unbalanced three phase loads. Compensation of grounded, ungrounded star connected and delta connected three phase unbalanced load has been carried out. Three ...
Comparison of PI, VSC and energy balance controller for single phase active filter control
(1998)
This paper presents a comparison among proportional-integral, variable structure voltage controller and energy balance controller for the control of single phase active filter. Proportional-integral (PI) and variable ...
An efficient approach for voltage security analysis and enhancement
(2000)
This paper presents an efficient one step look-ahead approach for post-contingency loadability limit analysis and its enhancement in critical cases. This is achieved by using steady state analysis tool judiciously within ...
Reactive power compensation and load balancing in electric power distribution systems
(1998)
This article presents a new method for reactive power compensation and load balancing in a four-wire, three-phase distribution system. An IGBT-based PWM voltage source inverter with a dc bus capacitor is used as a compensator. ...
Oscillatory stability limit enhancement by adaptive control rescheduling
(1999)
This paper presents a novel concept of utilizing adaptive corrective capability of the network for enhancing oscillatory stability limit.Researchers have analyzed this stability and suggested optimization of controller ...
An efficient approach for contingency ranking based on voltage stability
(2004)
This paper presents an efficient approach for line outage contingency ranking based on voltage stability concerns. This is achieved through non-iterative fast calculation of reactive support and voltage security indices ...
A review of single-phase improved power quality AC-DC converters
(2003)
Solid-state switch-mode rectification converters have reached a matured level for improving power quality in terms of power-factor correction (PFC), reduced total harmonic distortion at input AC mains and precisely regulated ...
Alleviation of line overloads and voltage violations by corrective rescheduling
(1993)
This paper presents simple and efficient algorithms for the alleviation of line overloads and voltage violations by corrective rescheduling. The proposed approach utilises the decoupling of real and reactive power and the ...
Discrete-mode automatic generation control of a two-area reheat thermal system with new area control error
(1989)
The authors deal with discrete-mode automatic generation control of an interconnected reheat thermal system considering a new area control error (ACE) based on tie-power deviation, frequency deviation, time error, and ...
Economic-emission load dispatch through goal programming techniques
(1988)
The economic-emission load dispatch problem which accounts for minimization of both cost and emission is a multiple, conflicting-objective function problem. Goal programming techniques are most suitable for such type of ...
