Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scheduled utility network control and utility broadcasting are implemented, then DSM program functionality is achieved, but implementation costs and device complexity increase
Solution Approach 1:
The system enables self-service by having the consumer's processor locally detect power grid transients and generate control signals without requiring utility provider communication infrastructure. The transient detector monitors electric parameters and autonomously generates DSM control signals that are applied to local electric loads, making the system independent of utility network control signals.
Solution Approach 2:
The power grid transient acts as an intermediary carrier that conveys utility resource status information from the power grid to the consumer's detection system. Instead of requiring direct communication between utility and consumer, the transient signals serve as a natural mediator that enables information transfer and subsequent control signal generation.
2Ease of operation
If utility network control signals are exchanged between utility provider and consumers, then DSM control is achieved, but communication infrastructure costs and device complexity increase
Solution Approach 1:
The system eliminates the need for utility-provider-to-consumer communication by enabling the consumer system to independently detect power grid transients and generate control signals. The processor analyzes transient characteristics and autonomously produces DSM control signals, making the entire control loop self-contained at the consumer premises without requiring external communication infrastructure.
Solution Approach 2:
The invention extracts the essential DSM control functionality from the utility communication infrastructure and relocates it to the consumer's local system. By taking out the control signal generation capability from the utility network and placing it at the consumer end, the system eliminates dependency on communication infrastructure while maintaining DSM control capability.
3Use of energy by moving object
If traditional DSM programs are implemented, then energy consumption management is achieved, but consumer comfort and adoption rate decrease
Solution Approach 1:
The system maintains consumer comfort by implementing self-service control where the consumer's own system generates and applies control signals locally based on real-time power grid transient detection. This eliminates the need for utility-imposed control that might compromise comfort, as the consumer retains full control over their electric loads while achieving energy management objectives.
Solution Approach 2:
The system implements continuous feedback by monitoring power grid transients and using this information to dynamically adjust control signals applied to electric loads. The processor continuously analyzes transient characteristics and modifies control signals in real-time, creating a closed-loop system that responds to actual power grid conditions while maintaining consumer comfort through adaptive control.

AI summary
The present specification relates to a power grid electric transient detector, a method of detecting a power grid electric transient, and an electric provisioning system detecting the power grid electric load. The power grid electric transient is estimated by receiving an electric parameter for electricity received from a power grid at a consuming facility. A digital filter extracts transient of the electric parameter. A processor analyzes the transients of the electric parameter and generates a power grid performance index based on the analyzed transient of the electric parameter.
