Wind Farm Setpoint Interface With User-Based Command Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wind farm management systems lack a uniform interface for external units to access and control wind farms, making it difficult to manage grid bottlenecks and regulatory requirements, such as 'Redispatch 2.0', due to the need for multiple interfaces and complex communication structures.
Innovation Solution
A method for providing setpoint values to a wind farm controller using a unified input interface on the wind farm server, where access data records authenticate external units and assign user identifiers to target values, allowing clear assignment and prioritization of commands across different units through the same interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple individual interfaces are provided for different external units, then each unit can access the wind farm controller with clear assignment and priority, but the system complexity increases and uniform access cannot be achieved
Solution Approach 1:
The patent implements a universal interface that can handle authentication and command transmission for multiple different external units (grid operators, plant operators, direct marketers) through a single standardized access point. This interface uses authentication records with unit identifiers to distinguish between different users while maintaining a unified communication channel, thereby reducing the number of interfaces from multiple unit-specific interfaces to one universal interface that serves all external units.
2Adaptability or versatility
If a uniform interface is added to existing wind farm servers, then different units can access via the same interface, but retrofitting is difficult and requires replacing the wind farm server
Solution Approach 1:
The patent segments the interface functionality into two independent parts: the authentication/identification module (handling access records, unit identifiers, and authentication logic) and the existing command transmission module. This segmentation allows the authentication module to be added or modified independently without replacing the entire wind farm server, enabling incremental implementation and reducing retrofit complexity while still achieving uniform interface capability.
3Ease of operation
If individual interfaces are assigned to each external unit, then priority management is simplified, but regulatory compliance for uniform access (Redispatch 2.0) cannot be achieved
Solution Approach 1:
The patent introduces an intermediary authentication record that sits between the uniform interface and the priority management system. This authentication record contains unit identifiers that allow the system to determine priority levels without requiring separate interfaces. The intermediary layer translates uniform interface access into prioritized command processing, thereby achieving both uniform access (regulatory compliance) and simplified priority management simultaneously.

AI summary
The invention relates to a method for sending setpoints (34) by a wind farm server (12) to a wind farm controller (13) of a wind farm (112), wherein the wind farm server (12) has an input interface (14) and setpoints (34) for the wind farm controller (13) are received via the input interface (14) after successful authentication by an access data record (20), wherein in the wind farm server (12) each of several access data records (20), which correspond to predefined access data records (23), is assigned one of several predefined user identifiers (26), wherein the user identifier (26) assigned to the access data record (20) is assigned to a setpoint (34) received from the input interface (20) by the wind farm server.which was used for successful authentication prior to receiving the setpoint (34) and received setpoints (20) are output to the wind farm controller (13) with the assigned user identifier (26). The invention further relates to a wind farm server (12) and a system with a wind farm server (12).
