Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current demand response systems in electric power grids face challenges in efficiently managing peak demand and incentivizing consumers to reduce energy consumption, especially with the increasing integration of intermittent power sources like wind power.
Innovation Solution
A power reduction system that includes a controller, network interface, and energy consumption module to selectively couple or decouple power sources from loads based on received power status messages, allowing for voluntary or automatic reduction in energy consumption, with the ability to utilize backup power sources and provide incentives for energy savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If demand response mechanisms are implemented to reduce peak power demand, then power grid reliability and system stability are improved, but consumer convenience and energy availability may deteriorate
Solution Approach 1:
The system pre-negotiates and establishes demand response agreements with consumers before peak demand events occur. Consumers voluntarily enroll in the program and pre-approve specific load reductions, ensuring their convenience is considered in advance while still achieving peak demand reduction goals
Solution Approach 2:
The system implements real-time monitoring and communication between utility and consumers during demand response events. Consumers receive notifications about upcoming load reductions and can provide feedback or adjust their participation, maintaining convenience while ensuring grid reliability
2Loss of energy
If switches are used to selectively couple/decouple power sources from loads, then energy consumption is reduced during peak demand, but device complexity increases
Solution Approach 1:
The system employs automated controllers that independently manage switch operations based on pre-programmed demand response signals and local conditions. This self-service capability reduces the need for complex centralized control infrastructure while achieving effective load management and energy reduction
Solution Approach 2:
The power distribution system is divided into independently controllable segments with individual switches for each load or load group. This segmentation allows selective decoupling of specific loads during peak demand without requiring system-wide complexity, enabling targeted energy reduction
3Measurement precision
If energy consumption measures are transmitted to remote devices for verification, then incentive payment accuracy is improved, but communication requirements and system infrastructure increase
Solution Approach 1:
The system utilizes existing multi-functional communication infrastructure that can serve multiple purposes: demand response signal transmission, energy consumption measurement reporting, and incentive payment coordination. This universal infrastructure reduces the need for dedicated communication systems while maintaining precise measurement and verification capabilities

AI summary
A power reduction system includes a central server and a plurality of power reduction devices. The central server of the power reduction aggregation system includes: a network interface configured to transmit and receive information to and from a communication network; a power grid status module coupled to the network interface and configured to transmit a power status message to the network, via the network interface, toward at least two power reduction devices connected to the network; and a power savings compensation module configured to determine an aggregate compensation earned for providing an aggregate energy reduction induced by the at least two power reduction devices in response to receiving the power status message, and further configured to determine individual portions of the aggregate compensation associated with each of the at least two power reduction devices.
