Development of a Preventive and Curative Congestion Management Module for Close to Real-Time Transmission System Operations

Inhalt:
To reduce costly preventive measures, existing system capacities should be more efficiently utilized in normal system state. In consequence, quick and relieving measures are needed in times of disturbances because of the higher loading of the lines. This approach of so-called curative measures is more and more discussed. To manage the proper ratio of preventive and curative measures according to system security requirements, optimization tools are needed. Furthermore, a decision support has to be provided for system operators to handle system security in an increasingly complex system. In the joint research project “InnoSys 2030”, PSI Software AG in cooperation with TenneT TSO GmbH, develop a “Preventive and Curative Congestion Management” (PCCM) module, which combines preventive and curative measures for congestion management considering an improved utilization of existing system capacities. This paper describes the concept of PCCM’s calculation cycles, its visualization concepts and the planned operation in the control center environment of TenneT.
