Energy Storage Dispatching for Urgent Load and Price Response

Solution Overview

Problem

Existing energy storage systems lack effective dispatching measures to maximize economic value and supply power to user equipment, especially in unexpected electricity consumption scenarios, failing to account for demand urgency and system capabilities.

Innovation Solution

A method and apparatus for controlling an energy storage system that acquires real-time power dispatching demands, user quotations for electricity consumption, and energy storage information to determine and prioritize power supply to user equipment based on demand urgency, generating targeted dispatching instructions to optimize power distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If charge and discharge is performed directly in response to a dispatching instruction or based on a remaining capacity of the energy storage system, then the system operation is simple, but the economic value of the energy storage system cannot be maximized

Engineering Contradiction:

Improvesystem operation simplicityVSAvoideconomic value

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent implements dynamic dispatching strategies that adjust charge and discharge operations based on real-time electricity prices, load demands, and system state. The control system dynamically selects from multiple dispatching modes (economic dispatching, reliability dispatching, combined dispatching) to optimize economic value while maintaining operational flexibility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by introducing multi-level discharge prices, demand urgency levels, and dynamic pricing mechanisms. These parameter changes enable the system to respond to varying economic conditions and maximize revenue through optimized charge-discharge timing and pricing strategies.

Inventive Principle:

Principle #35Parameter changes

2Stability of the object's composition

If the energy storage system uses a fixed dispatching method, then the system control is stable, but the system lacks flexibility to supply power in unexpected electricity consumption scenarios

Engineering Contradiction:

Improvesystem control stabilityVSAvoiddispatching flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic dispatching strategies that adjust charge and discharge operations based on real-time electricity prices, load demands, and system state. The control system dynamically selects from multiple dispatching modes (economic dispatching, reliability dispatching, combined dispatching) to optimize economic value while maintaining operational flexibility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system incorporates real-time feedback mechanisms that monitor electricity prices, load demands, and system state to continuously adjust dispatching decisions. This feedback loop enables the system to adapt to unexpected scenarios while maintaining stable control through proven algorithms and multi-mode operation strategies.

Inventive Principle:

Principle #23Feedback

3Productivity

If the energy storage system prioritizes power supply to user equipment with high demand urgency, then the economic value is improved, but the system may disrupt ongoing tasks

Engineering Contradiction:

Improveeconomic valueVSAvoidsystem stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic dispatching strategies that adjust charge and discharge operations based on real-time electricity prices, load demands, and system state. The control system dynamically selects from multiple dispatching modes (economic dispatching, reliability dispatching, combined dispatching) to optimize economic value while maintaining operational flexibility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system prepares for potential disruptions by implementing combined dispatching modes that balance economic objectives with system stability requirements. The multi-mode approach includes pre-defined strategies to handle transitions and maintain reliability when prioritizing high-value dispatching operations.

Inventive Principle:
