Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The volatility of renewable energy sources and consumer demands in electricity grids leads to unreliable power supply, necessitating a system that can dynamically adjust and balance energy distribution to meet short-term fluctuations and mismatches between sources and sinks.
Innovation Solution
An electrical power distributor with a circuit having at least three terminals, each with a power controller, a communication device, and a control means that adjusts power flows based on real-time data from sources and sinks, allowing for orchestration of power profiles to ensure sinks receive required power while managing surpluses or deficits through energy storage means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If buffer storage means are used to compensate for volatility in renewable energy sources and consumer demands, then supply reliability is improved, but device complexity increases
Solution Approach 1:
The electrical power distributor segments the electricity grid into multiple terminals (at least three terminals) that are electrically connected together, allowing independent control and monitoring of power flows between different sources and sinks. This segmentation enables localized power management while maintaining overall system reliability without requiring a single complex centralized buffer storage system.
Solution Approach 2:
The power distributor implements dynamic power adjustment through power controllers at each terminal that can continuously modify power flow based on real-time conditions. The system dynamically balances power distribution by adjusting the electrical connection states between terminals, enabling adaptive response to volatility in renewable energy sources and consumer demands without fixed buffer storage infrastructure.
2Adaptability or versatility
If power controllers are implemented at each terminal to adjust power dynamically, then adaptability is improved, but device complexity increases
Solution Approach 1:
The power distributor creates a universal control architecture where identical power controllers are deployed at each terminal, performing multiple functions including power adjustment, monitoring, and communication. This multi-functionality approach enables the system to adapt to various power distribution scenarios using the same standardized components, reducing the need for specialized complex equipment at each terminal.
Solution Approach 2:
The system implements feedback mechanisms where power controllers at each terminal continuously monitor power flow conditions and communicate with the overall control system. This feedback enables automatic adjustment of power distribution based on real-time measurements of voltage, current, and power levels, allowing the system to adapt dynamically without requiring complex manual control mechanisms.
3Measurement precision
If real-time data communication is implemented between control means and power controllers, then measurement precision is improved, but loss of information increases
Solution Approach 1:
The control means performs preliminary calculations of required power distribution based on forecasted power profiles of sources and sinks before actual power flow adjustments are needed. By pre-computing optimal power distribution strategies and storing them as control instructions, the system reduces the amount of real-time data communication needed while maintaining precise control, thereby minimizing information loss.
Solution Approach 2:
The system uses simplified representations or models of the actual power system state for control purposes. Instead of transmitting all raw measurement data, the control means works with copied or modeled power profile data that captures the essential characteristics needed for power distribution decisions, reducing communication overhead while maintaining measurement precision for control actions.

AI summary
A method of distributing electrical power in an electricity grid comprising an electrical distributor circuit having at least three terminals, wherein sources and sinks for electrical energy can be connected to the terminals, and wherein the three terminals are electrically connected together in such a way that an electric current can flow from each of the terminals to each of the other terminals. Each of the terminals has a respective power controller which is so adapted that in operation of the power distributor the electric power P(t) flowing by way of the respective terminal can be adjusted in dependence on time t. The control means is connected to each of the power controllers, and it calculates the electric power P(t) flowing by way of each of the terminals in dependence on the data received from the sources or sinks.
