Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial and commercial scenarios, the demand for energy storage control is complex and variable, making it challenging to achieve economical and efficient energy management for electrochemical energy storage systems.
Innovation Solution
A dispatch method for an energy management system (EMS) that integrates with a cloud terminal and a third-party control system, allowing for three dispatching modes: third-party dispatching, active dispatching, and passive dispatching, to adapt to different user demands and optimize energy storage power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed dispatching mode is used in the EMS system, then the system structure is simple, but the system cannot adapt to complex and variable energy storage control demands in industrial and commercial scenarios
Solution Approach 1:
The patent implements dynamic dispatching mode switching capability in the EMS system, allowing the system to transition between multiple dispatching modes (third-party dispatching, active dispatching, passive dispatching) based on real-time control demands. This dynamic adaptability resolves the contradiction by enabling the system to adjust its operational characteristics according to varying energy storage control requirements without requiring a completely different system architecture for each scenario.
Solution Approach 2:
The EMS system is designed with multi-functional dispatching capabilities, integrating three distinct dispatching modes within a single unified platform. The system can perform third-party dispatching (receiving instructions from external systems), active dispatching (autonomous optimization), and passive dispatching (local control) functions, all through the same EMS infrastructure. This universality allows the system to handle diverse energy storage control demands while avoiding the need for multiple separate systems.
2Productivity
If the EMS system autonomously makes dispatch decisions, then the response speed is fast, but the economy and efficiency of power control may be compromised without coordination with external systems
Solution Approach 1:
The patent establishes feedback mechanisms between the EMS system and external systems (cloud terminals, third-party control systems). The system receives dispatch instructions, curve data, and control parameters from external sources, processes this information through its autonomous decision-making algorithms, and adjusts its dispatch decisions based on the feedback received. This two-way communication ensures that autonomous operations are informed by external coordination information, optimizing both response speed and economic efficiency.
Solution Approach 2:
The EMS system performs preliminary autonomous analysis and preparation of dispatch strategies based on available information, while maintaining the flexibility to adjust decisions based on subsequent coordination with external systems. The system can pre-process control demands, evaluate multiple dispatch options, and prepare optimal strategies in advance, then refine these decisions through coordination with cloud terminals and third-party systems, ensuring both fast response and informed decision-making.

AI summary
The present disclosure provides a dispatch method of an energy management system for energy storage and a photovoltaic system for industrial and commercial use. The dispatch method includes: determining whether a third-party control system issues dispatch instructions, and initiating a third-party dispatching mode in response to determining that the third-party control system issues dispatch instructions; determining whether the cloud terminal issues dispatch curves, and initiating an active dispatching mode in response to determining that the cloud terminal issues dispatch curves; and initiating a passive dispatching mode in response to determining that the third-party control system does not issue any dispatch instruction and the cloud terminal does not issue any dispatch curve.
