RT23 |Real time simulation to test hybrid state estimation and WAMPAC functionalities

Within the PROGRESS research project, different aspects of curative network operation management are to be investigated. A strong focus of the work is on the testing of curative measures in field tests, which are flanked by analytical considerations of the research partners and tested in demonstrators. The project foresees two dedicated field tests, each with its own focus: Field Test I focuses on the exchange between different TSOs in the context of curative network management, whereas Field Test II focuses on the exchange of information between TSOs and DSOs. Furthermore, aspects of hybrid state estimation as well as steady-state and dynamic stimulation of curative grid operation management are investigated in the analytical support. A laboratory setup will be build at the Otto-von-Guericke-University to have a real time grid model connected to a control center through different communication protocols such as IEC 60870-5-104 and IEEE C37.118. The idea is to show the benfit of hybrid state estimation using PMU measurements in a real control center environment. Hybrid state estimation uses both PMU and Supervisory Control and Data Acquisition (SCADA) data. SCADA data provides information about the topology of the system, while PMU data provides real-time voltage and current measurements. This combined information is used to estimate the state of the system, taking into account both the static and dynamic characteristics of the system. Furthermore the laboratory setup is used to test WAMPAC functionalities. Wide-Area Monitoring Protection and Control systems (WAMPAC) enable various functionalities for monitoring network conditions and protection functionalities in network operation. One of these WAMPAC protection functionalities are Special Protection Schemes (SpPS, ENTSO-E Report). System automations do not serve the sole purpose of protecting specific equipment in cubicles (such as conventional protective relays), but rather serve to maintain the integrity of the entire power system and the security of supply over a larger observation area. The combination of the PMUs' ability to detect network conditions in real time and the protection functionalities of system automations creates a relevant research area for application in network operation.
