P–Q decoupled control schemes using fuzzy neural networks for the unified power flow controller

Developed cascaded multilevel inverter topology to minimise the number of circuit devices and voltage stresses of switches

“…The maximum output voltage can be evaluated by (6) V o max = nV dc (6) Fig. 1 Overall scheme of the proposed multilevel inverter topology www.ietdl.org…”

Robust terminal sliding mode power flow controller using unified power flow controller with adaptive observer and local measurement

“…P ‐ Q decoupled control scheme, based on fuzzy neural network presented in [8], could not completely interrupt the interaction between real and reactive power flow control.…”

“…neural network based controller [7], fuzzy neural network approach [8] and controllers based on the optimisation algorithms [9] are some intelligent controllers investigated on UPFC.…”

Application of genetic algorithm in optimization of unified power flow controller parameters and its location in the power system network

“…In addition, shunt-series configuration is not considered in the design of the FACTS. Hence, they (including devices such as UPFC) can independently and simultaneously control both the real and reactive power flow in the transmission line [12,13]. As for Mok et al [11], GA was used for optimizing only the parameters of UPFC damping controller.…”
