Server-Mediated Communication for Distributed Energy Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack an effective solution for communication with distributed devices handling electric energy via the Internet, particularly for operating virtual power plants, remote diagnosis, surveillance, data collection, and parameter modification.
Innovation Solution
A method involving a server that mediates communication connections between devices and partners based on generic properties and an initializing time-variable datum, allowing for point-to-point, point-to-multipoint, or multipoint-to-multipoint connections, using rules to determine the connections and transmit data with communication addresses and attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a server mediates communication connections between distributed devices and partners using rules based on generic properties, then communication efficiency and flexibility are improved, but server complexity and processing load increase
Solution Approach 1:
The communication system is segmented into multiple independent components: distributed devices, a mediating server, and communication partners. Each device is assigned a unique device identifier and possesses specific generic properties that are processed independently by the server. This segmentation allows the server to handle multiple communication requests in parallel without becoming a single point of complexity bottleneck.
Solution Approach 2:
The server acts as an intermediary that mediates communication connections between distributed devices and communication partners. It uses programmed rules to evaluate generic properties of devices and partners, and establishes appropriate communication connections (point-to-point, point-to-multipoint, or multipoint-to-multipoint) without requiring direct complex interactions between all participants. This intermediary approach simplifies the overall system architecture.
2Ease of operation
If the server mediates all communication connections and data transfers, then communication control and coordination are improved, but network bandwidth consumption and server processing load increase
Solution Approach 1:
The server performs partial mediation by only processing the minimum necessary information for connection establishment. It evaluates generic properties and device identifiers to determine connection types, rather than mediating every aspect of communication. This partial action approach reduces server processing load and network bandwidth consumption while maintaining adequate communication control.
Solution Approach 2:
Devices transmit their generic properties and device identifiers to the server in advance, before actual communication occurs. The server uses this preliminary information to pre-determine appropriate communication connections based on programmed rules. This preliminary action eliminates the need for complex real-time negotiations during actual communication, reducing both server load and network bandwidth consumption.
3Speed
If point-to-point connections are established between devices and partners, then communication directness and speed are improved, but system scalability and flexibility for group communications decrease
Solution Approach 1:
The system dynamically determines the type of communication connection to establish based on the generic properties of devices and communication partners, and the specific communication requirements. The server can select from point-to-point, point-to-multipoint, or multipoint-to-multipoint connections, allowing the system to adapt its communication topology dynamically rather than being fixed to a single connection type. This dynamic approach maintains communication speed while improving scalability and flexibility.

AI summary
A method of communication of distributed devices handling electric energy with communication partners via the Internet includes programming rules in a server. The rules determine between which device and which communication partner a communication connection is to be mediated based on generic properties of the devices, generic properties of the communication partners and an initializing time-variable datum. The communication connection is a point to point, point to multi point or multi point to multi point connection via the internet. Data are transmitted from each device and each communication partner to the server via the Internet. These data include both a communication address and attributes indicative of the generic properties of the device or the communication partner, respectively. The communication connection is mediated between the device and the communication partner determined by the rules in response to a value of the initializing time-variable datum also defined by the rules.
