Comparison of FACTS STATCOM models for damping oscillations in power system due to small perturbations
This paper presents small-signal stability studies of a multimachine power system, considering Static Synchronous Compensators (STATCOM)and discussed control modes of the STATCOM. The Power Sensitivity Model(PSM)is used ...
Optimal Power Flow with Voltage-Sensitive Loads in Distribution Networks
Traditionally, the optimal power flow (OPF) assumes a constant (active and reactive) power load model and thus it neglects the effect of the voltage sensitiveness of power load injections. As a consequence, the results ...
Design of the PI-UPFC-POD and PSS Damping Controllers Using an Artificial Bee Colony Algorithm
This paper presents two variations of the artificial bee colony (ABC) algorithm, the classical and a modified version, called GBest, for the design of the proportional-integral and supplementary damping controllers: power ...
UPQC implemented with Cascade Asymmetric Multilevel Converters
(Elsevier Science Sa, 2015-07)
The power quality (PQ) in distribution systems is affected by the pollution introduced by the customers. The Unified Power Quality Controller (UPQC) custom power device is the most integral actuator to improve the quality ...
Sensitivity analysis of stack power uncertainty in a PEMFC-based powertrain for aircraft application
(Pergamon-Elsevier Science Ltd, 2015-08)
Experimental data concerning the reliability of fuel cell systems (FCS) in aviation are still unavailable to technical community, while assessing reliability of a component or a whole system represents a fundamental aspect ...
Coordinated tuning of the parameters of PI, PSS and POD controllers using a Specialized Chu-Beasley's Genetic Algorithm
(Elsevier B.V., 2016-11-01)
This paper presents a Specialized Chu-Beasley's Genetic Algorithm (SCBGA) to perform coordinated tuning of the parameters of proportional-integral and supplementary damping controllers (power system stabilizers and interline ...
