by developing the level of life in societies, the need for new resources of energy becomes more important. in almost all cases, the aim is to convert one form of energy to the electrical form. with advances of technology and use of new electric and electronic devices and gadgets, the need for electrical energy is increasing and providing stable and continuous electric power becomes very importa...

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...

In this paper, the impacts of large-scale OWPPs penetration on Turkish power system is addressed. The grid compliance analyses for OWPP integration are carried out by using connection criteria defined in code. PV and QV curves obtained to assess effect static voltage stability limit. Eight scenarios conducted analyze dynamic characteristics grid. To observe impact frequency stability, transient...

in the past few decades, increasing growth of wind power plants causes different problems for the power quality in the grid. normal and transient impacts of these units on the power grid clearly indicate the need to improve the quality of the electricity generated by them in the design of such systems. improving the efficiency of the large-scale wind system is dependent on the control parameter...

To fully tap the abilities of renewables in reactive power optimization, this paper develops a detailed model for regulation capabilities wind turbines and photovoltaic units studies their impact on system’s operation. First, system with integration is established using AC flow. The are modeled detail according to topologies operating characteristics, then further simplified feasible region. An...
