WP2 - Smart Energy Network & IT Tools

WP2 objectives:

• Implement new market rules and associated incentives schemes related to

storage in a context of large renewable resources integration – T2.1 and T2.2

• Demonstrate the criticality of IT tools in enabling the deployment and efficient

use of storage systems in the framework of Smart Energy Networks – T2.3

Task 2.3 - Smart Dispatch Storage PSP

The intent within this task is to use smarter scheduling and dispatch techniques to

take advantage of variable-speed PSP assets, with the objective of providing as

much balancing flexibility as possible while meeting the main energy storage target

(i.e. energy transfer target)
