Battery DR Control Planning for Grid Power Resource Increase
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems do not effectively maximize the energy storage function of batteries to increase the power resource that can be supplied to a power grid during demand response (DR) periods.
Innovation Solution
A control device that adjusts the charging and discharging of multiple power storage systems by formulating a charging and discharging plan before the start of DR, utilizing an acquisition unit to gather participation intentions, a resource ensuring unit to identify power resources, and a communication unit to transmit the plan to the systems, thereby increasing the power resource available during DR execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If batteries are used for vehicle driving without preliminary control, then vehicle mobility is maintained, but the power resource that can be supplied to the power grid during DR execution is insufficient
Solution Approach 1:
The control device performs preliminary control by formulating a charging and discharging plan during a preliminarily controllable period before the DR execution period. This preliminary action adjusts the battery's charging state in advance, ensuring that sufficient power resources are available when the DR execution begins, thereby resolving the contradiction between maintaining vehicle mobility and increasing power supply capability during DR.
2Productivity
If the battery charging state is not adjusted before DR, then operational simplicity is maintained, but the power supply capability during DR execution is limited
Solution Approach 1:
The system performs charging state adjustment during a preliminarily controllable period that is predetermined before the DR start time. By executing the charging and discharging plan in advance, the system improves power supply capability during DR execution without causing time loss during the actual DR period, as all adjustments are completed beforehand.
3Power
If multiple power storage systems are coordinated without a formulated plan, then system flexibility is maintained, but the power resource optimization during DR is insufficient
Solution Approach 1:
The control device acquires information from multiple power storage systems about their driving plans and power capabilities, then formulates a coordinated charging and discharging plan based on this feedback. The system continuously monitors and adjusts the charging states of multiple batteries to maximize power resource availability during DR execution, resolving the contradiction between system flexibility and power resource optimization.

AI summary
A control device for controlling charging and discharging of power storage systems includes: an acquisition unit configured to acquire an intention to participate in a DR for adjusting a power supply and demand balance in a power grid from consumers when the DR is contracted in a power transaction; a resource ensuring unit configured to ensure, from the power storage systems, a power resource that the power storage systems are able to supply to the power grid during an execution period of the DR; a plan formulating unit configured to adjust a charging state of each of the power storage systems during a preliminarily controllable period that is a predetermined period before a start of the DR and formulate a plan for increasing the power resource able to be supplied during the execution period; and a communication unit configured to transmit the plan to the power storage system.
