In recent years, with the increasing of wind farm's capacity, requirements of the ability of fault ride through for wind farm are getting more and more stringent. The article analyzes the methods improving the low voltage ride through capability of the constant speed constant frequency wind power generation system. Static Synchronous Compensator (STATCOM) and Series Dynamic Breaking Resistor (SDBR) have recently been reported as stabilization methods for fixed-speed wind generator systems. Simulation results demonstrate that the STATCOM is a cost-effective solution for transient stability enhancement and minimization of voltage fluctuations, while the BR is the simplest in structure and a cost-effective solution for transient stability enhancement. Then a method is prompted, which Combines STATCOM and SDBR to promote the fault ride-through ability of constant speed constant frequency wind power system. By this way, the system validity and stability can be improved while costs can be cut down.

The increasing penetration of wind energy to the conventional power system due to the rapid growth of energy demand has led to the consideration of different wind turbine generator technologies. In fault conditions, the frequency of the power system decreases and eventually leads to speed differences between the grid and the interconnected wind generator. This can result to power system problems such as transient instability (TS). This paper focuses on enhancing the TS of a permanent magnet synchronous generator (PMSG)-based power system during 3ph fault conditions using FACTS devices. The power system considered is connected to a large wind farm which is based on PMSG. Critical clearing time (CCT) is used as an index to evaluate the transient state of the system. Under the study of an IEEE-14 bus system using PSAT as a simulation tool, the integrated CCT with PMSG-based wind turbine is improved with three independent FACTS devices. One of the synchronous generators in the test system has been replaced at random with the PMSG-based wind turbine which is meant to generate an equivalent power. Time domain simulations (TDSs) were carried out considering four study cases. Simulation results show that the (CCT) of the system with the FACTS devices is longer than the CCT without them, which is an indication of TS improvement.

Enormous penetration of wind power in power systems and its contribution in covering a major part of grid load demand, require higher stability during disturbances. The most important issue of wind generators is the early outage of several generating units when a sudden voltage drop occurs in the grid. Voltage drops near wind generators are mainly due to abrupt load rises and integration of large-scale factories and industrial units into the grid. In this paper, the case study of Binalood wind farm is studied, analyzed, and simulated. Then, various proposed methods are investigated in terms of stability enhancement such that when a disturbance appears near the Binalood wind farm, it can hold up its stability and connection to the grid. Simulations are carried out using Matlab and Simulink.
