Dynamic Power Storage for Grid Disruption Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power grid systems lack mechanisms to incentivize distributed power production units to produce power when demand is high or to oversupply beyond their own needs, as conventional net metering does not account for real-time power demands and may charge participation fees.
Innovation Solution
A server monitors and predicts temporary power disruptions in a power group, sending control messages to divert power to local storage and condition power supply based on stored energy during disruptions, using dynamically negotiated rates that incentivize production during high-demand periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional net metering is used to credit distributed power production units, then operators receive fixed pre-negotiated rates for power supplied to the grid, but operators are not incentivized to produce power during high-demand periods or to establish oversized production capacity
Solution Approach 1:
The patent implements dynamic pricing where the crediting rate varies based on real-time grid conditions, specifically the ratio of distributed power production to total power demand. When demand is high or distributed production is low, operators receive higher credits, creating a dynamic incentive structure that adapts to changing grid needs rather than using fixed rates
Solution Approach 2:
The system continuously monitors grid parameters including total power demand and distributed power production, using this feedback to adjust crediting rates in real-time. This closed-loop feedback mechanism ensures operators receive incentives aligned with current grid conditions, motivating increased production during high-demand periods
2Reliability
If distributed power production units supply power to the grid during peak demand, then grid stability is improved, but operators face potential participation fees under conventional net metering without adequate compensation
Solution Approach 1:
The patent changes the economic parameter of crediting rates based on grid conditions. During peak demand periods when grid stability is most critical, the system automatically increases the crediting rate parameter, ensuring operators receive adequate compensation for providing stability services rather than facing net metering participation fees
3Reliability
If a server monitors and predicts power disruptions to send control messages for power storage, then power distribution stability is enhanced during disruptions, but system complexity increases due to monitoring and control infrastructure
Solution Approach 1:
The server continuously monitors grid parameters and predicts potential power disruptions before they occur, sending control messages to storage units in advance to prepare for upcoming disruptions. This preliminary action allows the system to enhance reliability during disruptions without requiring complex real-time response mechanisms, as storage units are already positioned to provide power when needed

AI summary
In an embodiment, a server monitors a set of parameters associated with future power production capacity of a set of distributed power production units that belong to a power group supplying power to a given serving area of a power grid during a given period of time. The server predicts, for a portion of the given period of time, a temporary power production disruption that will affect the power group based on the monitoring. The server sends a control message to the power group based on the prediction. At least one power production unit in the power group receives the control message, and responsive to the control message diverts at least a portion of power being supplied to the given serving area to local storage, detects the temporary power disruption and conditions power supplied to the given serving area during the temporary power distribution based upon the locally stored power.
