Development of a benchmark on EMTP for the test of grid forming power electronic converters785

Abstract
In the next years, the grid forming control will become a reality in the transmission grid. This a major milestone for the grid in order to be able to integrate even more power electronic converters a... see morend it represents also a major challenge. For doing so, the TSO will need to develop a bench mark to test the behavior of this new types of control. This presentation gives a first proposal of benchmark and give some example of the test on several types of grid forming controls. All the simulation model are developed on EMTP.

EMTP® studies for IBR integration at Hydro-Quebec777

Abstract
Abstract:

Hydro-Quebec has been involved in EMTP® development since the 80s and has collaborated with several organizations worldwide through the Development Coordination Group of EMTP (DC... see moreG-EMTP). Hydro-Quebec was the key player in the EMTP recoding project that allowed the delivery of the latest generation of the software in 2003. The new EMTP was developed at IREQ (Hydro-Quebec’s research center) from 1998 to 2003.

Hydro-Quebec was the first organization to simulate its complete transmission grid in EMTP. Hydro-Quebec was also the first system operator to require that manufacturers of wind turbines provide detailed EMT-type (EMTP®) models for wind park integration studies. This webinar will present:
• How EMTP simulations are integrated into Hydro-Quebec’s work process?
• How EMTP simulations can complete RMS simulations?
• Future simulation challenges

Speakers:
• Karine Gauthier, ing.
• Pascal Prud’homme, ing.

Use of EMTP in Transmission Planning Research772

Abstract
The initiation of inverter-based generation (IBG), has been changing the characteristics of the grid. The addition of non-traditional generation sources gives rise to several grid concerns, such as re... see moreduced short-circuit fault current capacity and system inertia as well as ineffective voltage regulation. Because of this – the use of EMT studies has been becoming more common to accommodate “special” studies. This presentation will just highlight a few examples of the use of EMTP in transmission level planning.

Stability analysis of the CCS power plant769

Abstract
This work shows the simulations performed using EMTP before and after tuning the PSS of the Coca Codo Sinclair hydro power plant (1500 MW) of the National Interconnected System of Ecuador. Each machin... see moree in the plant is modeled and its control systems (AVR and PSS) are represented by models created by the user and by library models. The results obtained are compared with real signals taken by the Wide Area Monitoring Systems.

In addition, the analyzes performed are shown, from a point of view of the transient stability of the plant, to determine the adjustment of the single-phase reclosing dead time of the San Rafael – El Inga transmission line, at 500 kV, taking into account the secondary arc model of the EMTP library.

EMT models to evaluate traveling wave based protection in distribution system767

Abstract
This presentation will discuss the need for using wide-band models to model the traveling wave phenomenon in the distribution system. The distribution system is going through significant changes. On... see moree of them is the high penetration of inverter-based distributed energy resources in the distribution system. Due to this high penetration, there is a need for a better protection system. Multiple organizations are working on creating novel protection techniques for distribution systems with high penetration of inverter-based DERs. One such innovative method is the use of traveling waves to detect and locate faults. Transmission system protection utilizes this approach, and commercial solutions exist for the transmission system. Using this approach in the distribution system is not straightforward and presents some challenges for implementation.
