Solution Overview

Problem

Existing WAMPAC systems require significant manual effort for setup and expansion, and adding new capabilities is complicated due to the need for interoperability among devices from different manufacturers, especially when dealing with complex operator structures in energy networks.

Innovation Solution

A method involving agent devices assigned to subnetworks that transmit offer messages with subnetwork-specific measures, a network control arrangement that receives and selects these measures, and a central platform that acts as a broker for decentralized control, allowing for simplified integration of diverse equipment and quick response to network faults.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a centralized WAMPAC system with standardized protocols is used to ensure interoperability among devices from different manufacturers, then reliability is improved, but device complexity and manual setup effort increase significantly

Engineering Contradiction:
ImproveinteroperabilityVSAvoidmanual setup effort
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary component that acts as a translator or adapter between devices using different communication protocols and the central WAMPAC system. This intermediary handles protocol conversion and standardization automatically, ensuring interoperability while eliminating the need for manual configuration of communication parameters. The intermediary absorbs the complexity of protocol harmonization, allowing devices from different manufacturers to communicate reliably without increasing overall system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If new capabilities are added to the WAMPAC system through custom calculation methods, then adaptability is improved, but device complexity and configuration effort increase due to complicated network studies and load flow calculations

Engineering Contradiction:
Improvenew capabilitiesVSAvoidconfiguration effort
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the complex calculation methods into modular, independently configurable components. Each new capability is implemented as a separate module that can be added or removed without affecting the entire system. This modular approach allows custom calculation methods to be integrated through simple module registration rather than requiring comprehensive network studies and load flow calculations for each new capability, significantly reducing configuration effort while maintaining adaptability.

Inventive Principle:
Principle #1Segmentation

3Reliability

If manual configuration is used to ensure standardized control in WAMPAC systems, then reliability is improved, but productivity decreases due to large amounts of manual effort required for setup and expansion

Engineering Contradiction:
Improvestandardized controlVSAvoidsetup speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements self-service mechanisms where devices automatically configure themselves when joining the WAMPAC system. Upon connection, devices perform automatic discovery, register their capabilities, and obtain necessary configuration parameters without human intervention. This self-configuration process maintains standardized control through automated validation against WAMPAC specifications while dramatically increasing productivity by eliminating manual setup steps for each device addition.

Inventive Principle:
Principle #25Self-service

4Measurement precision

If complete knowledge of network topology is required for centralized control, then measurement precision is improved, but device complexity increases as the central system must process and store extensive network information

Engineering Contradiction:
Improvenetwork state knowledgeVSAvoidcentral system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements a distributed intelligence approach where each device maintains local knowledge of its immediate network environment and topology. Instead of requiring the central system to possess complete network topology information, each device autonomously determines and acts upon local network conditions. This local quality approach maintains precise measurement and control capabilities while significantly reducing the information processing burden on the central system, as each device independently handles its own control decisions based on locally available data.

Inventive Principle:
Principle #3Local quality

AI summary

A method for controlling an energy network includes transmitting a respective offer message by using a plurality of agent devices, each agent device being assigned to a subnetwork of the energy network, and each offer message indicating a subnetwork-specific measure for controlling the respective subnetwork and a period for which the subnetwork-specific measure is offered. A network control arrangement is used for receiving the offer messages, and identifying an undesirable network state of the energy network. A subnetwork-specific measure is selected from the plurality of subnetwork-specific measures, and an acceptance message is transmitted to that agent device which sent the offer message containing the selected subnetwork-specific measure by using the central network control arrangement. A corresponding agent device, a corresponding network control arrangement and a system including an agent device and a network control arrangement are also provided.
