“…But as far as the rotor angle stability is concerned, DFIGs with terminal voltage control capability can minimize rotor angle deviation and in turn improve the rotor angle stability [37]. However, different combinations of generators and load can affect power system transient stability [38].…”

Various wind turbines have been developed and operated in distribution systems and transmission systems. The usage of wind power is now rapidly growing worldwide and some leading countries in wind power technologies have been developing new strategies and enhanced requirements for power system security and electrical power quality. But most of power systems have not prepared for them yet. Given the fact that the renewable energy sources, such as wind power, photovoltaic, fuel cells will be getting more importance for the future energy systems with the benefit of emission trading, most of developing countries and power systems that are not preparing for such movement should make their future plan not only for the power system security, but also for their economic development. In this paper, wind power technologies, which is one of the most promising alternative energy sources, is summarized from the viewpoint of power system operation and control.

“…e dynamic equations of power system due to the introduction of power-electronic interfaces become more complex, and it is difficult to analyze the influence of renewable energy on the power system stability. In recent years, with the increasing maturity of detailed models of wind power, photovoltaic, and other renewable energies, the research on the stability of power system with large-scale renewable energy mainly relies on numerical simulation methods [1][2][3][4][5][6][7][8], namely, establishing a detailed mathematical model for simulating the dynamic process of renewable energy, and carrying out the numerical simulation through such stability analysis software as BPA, PSASP, and PSS/E. e numerical simulation method has the advantages of good model detail and high precision and can simulate the response characteristics and dynamic process of renewable energy in detail.…”

Coupled with the power system through power-electronic interfaces, renewable energies including wind power and photovoltaic can control the power quickly and flexibly. In the steady-state stability analysis, by neglecting the fast dynamics of power-electronic interfaces, the renewable energy power is simplified to a static power injection model and can be described as an algebraic equation in the dynamic process. Based on this simplified model, the steady-state stability of sending-end system with mixed synchronous generator and power-electronic-interfaced renewable energy is studied. By proposing a triangular transformation model based on the classical model of power system, the steady-state stability analysis becomes feasible. The mechanism of steady-state stability is revealed, and the influence of renewable energy on the steady-state stability limit is quantitatively investigated. When the renewable energy power increases, the steady-state stability limit of the sending-end system first increases and then decreases. Reducing the power output of synchronous generator can change for a higher integration limit of renewable energy. Simulation results validate the conclusion.

“…To find the equivalent inertia of all power sources, i.e., generators or wind turbines, the use of synchronous pharos measurement can found in [16]. Authors of [17] explored the relationship between wind power generation and the rotor angle stability of conventional synchronous generators from the viewpoint of controlling the reactive power from variable speed wind turbine generators in the system. The authors presented an investigation on wind turbine contribution to the frequency control of non-interconnected island systems in [18], and a novel frequency regulation by DFIG-based wind turbines was presented in terms of coordinating inertial control, rotor speed control and pitch angle control for the low, medium or high wind speed mode [19].…”

Abstract:To compensate for the ever-growing energy gap, renewable resources have undergone fast expansions worldwide in recent years, but they also result in some challenges for power system operation such as the static security and transient stability issues. In particular, as wind power generation accounts for a large share of these renewable energy and reduces the inertia of a power network, the transient stability of power systems with high-level wind generation is decreased and has attracted wide attention recently. Effectively analyzing and evaluating the impact of wind generation on power transient stability is indispensable to improve power system operation security level. In this paper, a Doubly Fed Induction Generator with a two-lumped mass wind turbine model is presented firstly to analyze impacts of wind power generation on power system transient stability. Although the influence of wind power generation on transient stability has been comprehensively studied, many other key factors such as the locations of wind farms and the wind speed driving the wind turbine are also investigated in detail. Furthermore, how to improve the transient stability by installing capacitors is also demonstrated in the paper. The IEEE 14-bus system is used to conduct these investigations by using the Power System Analysis Tool, and the time domain simulation results show that: (1) By increasing the capacity of wind farms, the system instability increases; (2) The wind farm location and wind speed can affect power system transient stability; (3) Installing capacitors will effectively improve system transient stability.
