Wind energy is a major source of power in over 70 countries across the world, and the worldwide share of wind energy in electricity consumption is growing. The introduction of significant amounts of wind energy into power systems makes accurate wind forecasting a crucial element of modern electrical grids. These systems require forecasts with temporal scales of tens of minutes to a few days in ...

Wind power is sustainable, renewable and clean energy. There are abundant wind resources in Yunnan province, China. In recent years, wind power integration has developed rapidly in Yunnan province. With the first batch of the wind farm being built and a part of them going into production in Yunnan, the wind power resources will be large-scale developed and utilized in the future. Based on the w...

The proper modeling of wind energy projects in system studies is becoming increasingly important to system operators and transmission system owners. The amount of wind generation is growing rapidly and wind farms are growing in size and complexity. Wind farms are being installed consisting of hundreds of units, with the wind farm capable of producing hundreds of MW. The location of a wind farm ...

Using the FACTS controllers, such as static synchronous compensator (STATCOM), as it provides continuous reactive power, in the grid including wind turbine (WT) equipped with doubly fed induction generator, for improving voltage profile (under normal circumstances) and providing a transition ability from inductor generator transition state has been proposed. In this paper, in order to contr...

The investigation and determination of the impact of DFIG wind farms and their controllers on power system transient performance require power system simulation and analysis tools that incorporate both an accurate dynamic model of a DFIG wind turbine and a realistic representation of a power network [1]. This paper investigates the dynamic performance of DFIG wind turbines in multiple machine s...

The Voltage Source Converter-HVDC (VSC-HVDC) system applied to wind power generation can solve large scale wind farm grid-connection and long distance transmission problems. However, the low voltage ride through (LVRT) of the VSC-HVDC connected wind farm is a key technology issue that must be solved, and it is currently lacking an economic and effective solution. In this paper, a LVRT coordinat...

In this paper, a model predictive control (MPC)-based coordinated scheduling framework for variable wind generation and battery energy storage systems (BESSs) is presented. On the basis of the short-term forecast of available wind generation and price information, a joint look-ahead optimization is performed by the wind farm and storage system to determine their net power injection to the elect...

Wind energy represents one of the least cost methods of electricity generation, produces no carbon emissions, and is highly scaleable. However, the intermittency of wind and the passive reaction of wind turbines means spinning and scheduled reserves are required to ensure grid security. It is vital for transmission network planning that temporally and spatially accurate models of wind power are...

Doubly Fed Induction Generators DFIG are nowadays widely used in variable speed wind power plants. The dynamic interaction between variable speed DFIG wind turbines and the power system which is subjected to disturbances, such as short circuit faults, is an important issue. The ability of the wind power plant to stay connected to the grid during disturbances is important to avoid a cascading ef...
