Nowadays, different power systems are connected to each other due technical and economic reasons form a complex developed network. Such networks measure send system data decision-making centers for control protection. This information transmission is accompanied by delay causes the performance of system’s damping controllers be affected. To improve dynamic stability, supplementary controller in...

FACTS devices are used to control the power flow, to increase the transmission capacity and to optimize the stability of the power system. One of the most widely used FACTS devices is Unified Power Flow Controller (UPFC). The controller used in the control mechanism has a significantly effects on controlling of the power flow and enhancing the system stability of UPFC. According to this, the ca...

Power system engineers are currently facing challenges to increase the power transfer capabilities of existing transmission system. This is where the Flexible AC Transmission Systems (FACTS) technology comes into effect. With relatively low investment, compared to new transmission or generation facilities, the FACTS technology allows the industries to better utilize the existing transmission an...

In this paper, a new topology for Interline Dynamic Voltage Restorer (IDVR) is proposed. This topology contains two direct three-phase converters which have been connected together by a common fictitious dc-link. According to the kind of the disturbances, both of the converters can be employed as a rectifier or inverter. The converters receive the required compensation energy from the gird thro...

The unique capability of the Unified Power Flow Controller in multiple line compensation are integrated into a generalized power flow controller that is able to maintain prescribed and independently controllable, real power and reactive power flow within the line. We demonstrate the proposed technique on a single machine infinite bus system. In this paper, we propose UPFC with PSS design scheme...

this paper introduces an indirect adaptive fuzzy sliding mode controller as a power system stabilizer for damping local and inter-area modes of oscillations of multi-machine power systems. this controller is designed based on the combination of sliding mode controller and the fuzzy logic systems. the fuzzy systems are used to approximate the unknown functions of power system model. generator sp...
