Overview

PEGASE is a four-year project dealing with high and extra high voltage transmission and sub-transmission networks in Europe, and implemented by a consortium composed of 20 Partners including: TSOs, expert companies, and leading research centers in power system analysis and applied mathematics. The heart of the PEGASE project involves advanced algorithmic build prototypes of software, demonstrations of the feasibility of real-time state estimation (SE), multi-purpose constrained optimization (OPF), and time-domain simulation of a large model representative of the Electricity Transmission Network (ETN), taking into account its operation by multiple TSOs.

Project Ambitions

The R&D ambitions of PEGASE were as follows:

• to relieve all knowledge barriers to provide TSOs with a synchronous display of the state of the ETN, very close to real time (typically each 5-10 seconds)
• to develop OPF programs determining realistic system operating points that include TSO operating rules and optimal preventive or corrective actions, typically for real-time congestion management
• to improve the existing state of the art technology in time simulation of very large systems to permit:
  • off-line studies of the ETN including possibly interconnections with neighboring systems
  • dispatcher training simulation
  • preventive security assessment, and in on-line emergency conditions, faster than real-time simulation opening new perspectives for an anticipative control of the system

Project Impacts

The availability of duly tested prototypes allows for a quick implementation of the developed tools in a central facility and in existing computing environments. A better management of crisis allows for decreasing conservative security margins and improving the identification of real risks. Eventually, the first European dispatcher training simulator will be at arm’s length for use in a European training center, allowing for the simultaneous training of dispatchers from several countries.
