Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If back-up batteries in radio access networks are used as additional power capacity providers to balance the power grid, then power grid balancing utility is improved, but radio network stability may deteriorate
Solution Approach 1:
The system dynamically adjusts the operational state of back-up batteries based on real-time conditions. The VPP controller receives site information including battery state of charge, geographical location, and energy balancing related information, then determines control information that optimizes virtual power plant utility while maintaining radio network stability. This dynamic adaptation allows the system to respond to changing grid conditions and network requirements.
Solution Approach 2:
The system changes key parameters such as state of charge thresholds, operational modes, and control policies based on current conditions. By adjusting these parameters dynamically, the system can optimize power grid balancing utility at different times while ensuring radio network stability is maintained through appropriate parameter selection and constraint enforcement.
2Productivity
If control information is determined to optimize virtual power plant utility, then power plant utility is improved, but system complexity increases
Solution Approach 1:
The VPP controller acts as an intermediary between the radio access network elements and the power grid. It receives site information from radio access network elements, processes this information along with energy balancing related information, and generates control information that is transmitted back to the virtual power plant entities. This intermediary architecture simplifies the overall system by centralizing the control logic and decision-making process.
Solution Approach 2:
The control system is segmented into distinct functional components: obtaining site information, obtaining energy balancing related information, determining control information based on multiple inputs, and transmitting control information to virtual power plant entities. This segmentation allows each component to be developed, tested, and maintained independently while working together to achieve the overall goal of optimizing virtual power plant utility.

AI summary
Solutions to control use of back-up batteries of a radio access network in a virtual power plant are disclosed. In the solutions, a virtual power plant manager entity obtains site information on radio access network element sites, at least some of which are usable as additional power capacity providers in the virtual power plant, and energy balancing related information of a power grid using the virtual power plant. The virtual power plant manager entity determines, based at least on the site information and the energy balancing related information, for at least one virtual power plant entity for the virtual power plant, control information relating to the virtual power plant, the control information optimizing virtual power plant utility while maintaining radio network stability, and transmits said control information to the at least one virtual power plant entity.
