Based on the wind-turbine characteristics, a method of tracking the maximum wind energy using fuzzy logic principles, without the wind velocity measurement is proposed, which is independent of the turbine parameters and air density. The generator is operated in the indirect speed control mode with the speed reference being dynamically modified by fuzzy logic system in accordance with the magnitude and direction of active power changing. By analyzing the mathematical model of a doubly-fed induction generator (DIFG) and the filed-oriented vector transformation control scheme, the whole variable-speed constant-frequency (VSCF) wind-power generation is formed. The simulation results validate the correctness of the proposed control strategy.
An increasing presence of renewable energy forms, due to environmental and socio-economic reasons, in the electric power industry necessitates an assessment of the impact of these sources, on a conventional electric utility. This assessment incorporates stochastic theory to investigate the security and stability of a wind energy conversion system (WECS) on an electrical utility to quantify the limits of such a system's operation. This paper presents a model that captures the uncertainties in the system load at the wind generator bus, a method that approximates the randomness experienced by the system. Future dynamic models in development will capture noise due to wind effects. A simple model of a grid-connected WECS is presented. An index of reliability is also determined known as the mean first passage time (MFPT), the time taken for the system to leave its stability region.
Summary form only given. Although the installed wind generation capacity has grown remarkably over the past decades, percentage of wind energy in electricity supply portfolio is still relatively low. Due to the technical limitations of power system operations, considerable wind generation cannot integrate into the grid but gets curtailed. Among various factors, transmission congestion accounts for a significant portion of wind curtailment. Derived from DC power network, an analytical approach is proposed to efficiently assess the congestion induced wind curtailment sensitivity without iterative simulation. Compared to empirical simulation-based wind curtailment studies, the proposed approach offers the following advantages: 1) computational efficiency, 2) low input information requirement, and 3) robustness against uncertainties. This approach could benefit system operators, wind farm owners as well as wind power investors to better understand the interactions between wind curtailment and power system operations and can further help for curtailment alleviation. Numerical experiments of a modified IEEE 24-bus Reliability Test System (RTS) as well as a practical 5889-bus system are conducted to verify the effectiveness and robustness of the proposed approach.

Type 3 wind generators in series compensated networks could lead to subsynchronous resonances (SSR). Previous research focuses on balanced operation only. In this paper, impact of unbalance on Type 3 wind energy systems is investigated in two aspects: (i) impact on electric resonances and (ii) impact on torsional resonances. In the first aspect, impedance models of the system in DQ domain and phase domain are developed. Particularly, negative sequence impedances are examined. Nyquist stability criterion is applied to detect possible resonances. In the second aspect, transfer functions of the electromagnetic torque versus the rotating speed due to negative sequence components are developed. The impact of negative sequence components on electromechanical damping is then analyzed. The analysis results are verified by time-domain simulation results.

In recent years, renewable energy supply in the U.S. has increased dramatically, among which wind energy has experienced the largest growth. Since the grid is not designed to handle high levels of intermittent generation, involuntary wind curtailment has been implemented commonly in many regional transmission organizations. Transmission congestion is one of the main barriers, which avoids full delivery of the produced wind energy. An obvious but extremely costly solution to this problem is building new transmission lines. Alternatively, transfer capability over the existing transmission system can be enhanced using variable-impedance flexible AC transmission system (FACTS) devices. This paper proposes a two-stage stochastic optimization model for integrating FACTS into power system operation for a system with high levels of wind penetration. The first stage identifies an optimal base dispatch, while the second stage finds the optimal deployment of FACTS flexibilities and operational reserves for each wind scenario. Using this model, the paper studies the impacts of FACTS operation on wind energy integration. The simulation studies on an RTS-96 system verify the effectiveness of the proposed method in reducing the operation cost as well as wind curtailment. The proposed model is also computationally- efficient, as a linear FACTS model is employed.
This paper deals with the problems related to an islanding experiment performed at Rejsby Hede in Denmark. During the experiment several interesting observations were made in connection to distortion of voltages and currents. Observations were also made in connection to variation of frequency and phase. In this paper the data are analyzed in three different ways and the results are related to the physics of the electric system.
