How does a centralized wind farm control system work?
The successful coordination between wind turbines and system operators is accomplished by using a centralized wind farm control system. The wind farm control system acts as a central part of the system and distributes active power references among wind turbines.
What is a wind farm control system?
The control system is the core of wind farm operations and has an essential influence on the farm's power capture efficiency, economic profitability, and operation and maintenance cost. However, the inherent system complexities of wind farms and the aerodynamic interactions among wind turbines cause significant barriers to control system design.
What is the control system for wind turbines?
The proposed control system is based on a complex hierarchical control architecture. A central supervisory control level decides the active and reactive power references for each wind turbine local control level, based on received production orders (maximum production or power regulation) from the system operator.
What is the central control level of a wind farm?
The central control level with its different control modes, ordered from the system operator level, is sending out reference signals to all the local wind turbine controllers. These controllers ensure that the overall target of the wind farm controller is reached.
Which methods are used in wind farm control?
Typical methods include PSO, RS, GA, SCP, etc. The majority of wind farm control tasks require direct adjustments in wind turbine states. Relevant tasks considered in this paper include power generation maximization, fatigue load minimization and power reference tracking.
What are some examples of wind farm control studies?
In addition, many other wind farm control studies considerimportant tasks in the grid integration and transmission network of wind energy. For example, designed an RL-based adaptive wind farm control method to enhance the stability of power systems with wind energy penetration.
