EMS Power Scheduling via Temporal Plan Standardization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy management systems (EMS) face challenges in interconnecting power delivery and reception plans across independent systems due to differing temporal gradings, making it difficult to maintain supply-demand balance and integrate systems hierarchically, especially when power storage equipment is not uniformly distributed.
Innovation Solution
A power demand and supply scheduling apparatus that exchanges reservation information between EMSs to create a unified power delivery and reception plan, utilizing storage battery capacity and predicting power generation and load to balance power amounts across each unit time zone, allowing for flexible and coordinated power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent EMSs create power delivery and reception plans independently, then each system maintains operational autonomy, but interconnection with integrity of plans becomes difficult due to differing temporal gradings
Solution Approach 1:
The patent introduces a standardized temporal grading structure as an intermediary framework that enables independent EMSs to exchange power plans with consistent time resolutions. This mediator allows autonomous systems to maintain their operational independence while ensuring plan integrity through standardized temporal representation, resolving the contradiction between autonomy and integration reliability
Solution Approach 2:
The patent transforms power plans by standardizing their temporal parameters to a common grading structure. By changing the temporal representation parameters of power delivery and reception plans to match a standardized framework, the system enables reliable interconnection while preserving operational autonomy through parameter harmonization rather than structural integration
2Adaptability or versatility
If power delivery and reception plans are created with different temporal gradings, then flexibility in power management is improved, but coordination and interconnection among EMSs becomes difficult
Solution Approach 1:
The patent segments power plans into standardized temporal units that can be flexibly aggregated or divided. By breaking down power delivery and reception plans into uniform temporal gradings, the system maintains flexibility in power management while enabling easy coordination through standardized segments that can be systematically combined and matched across different EMSs
Solution Approach 2:
The patent creates a universal temporal grading framework that serves multiple functions: it standardizes plan representation, enables flexible power management through consistent time units, and facilitates coordination among diverse EMSs. This universal structure allows the same temporal framework to handle various power management scenarios while maintaining ease of operation through standardized procedures
3Reliability
If supply-demand balancing is enforced at each unit time zone, then power system stability is improved, but the room for flexible power interchange among EMSs is reduced
Solution Approach 1:
The patent applies preliminary balancing actions within each unit time zone by pre-calculating and standardizing power delivery and reception plans before interchange. This preliminary action ensures supply-demand balance is maintained at each temporal segment, providing system stability while the standardized framework enables flexible interchange by resolving balancing requirements in advance, allowing EMSs to exchange power within established parameters
