Closed-loop Synthetic Inertia Control of a Variable-speed Wind Turbine Generator834

Abstract
This presentation introduces a closed-loop SIC scheme of a doubly-fed induction generator (DFIG), which relies on the measured frequency. The SIC scheme employs an additional control loop that operate... see mores in conjunction with the MPPT control loop. Simulation results using an EMTP simulator will be presented under various wind and system conditions for the IEEE 14-bus system.

Screening Studies for Susceptibility to Sub Synchronous Control Interaction using EMTP848

Abstract
Sub Synchronous Control Interaction (SSCI) is can occur between type 3 wind turbines and a series capacitor. SSCI events can result in severe overvoltages that can damage equipment on the transmission... see more system. This presentation will provide a brief history of SSCI, its impacts on the power system, and how to perform screening studies for SSCI susceptibility using EMTP… The presentation will also include a discussion of challenges encountered, and key results observed, during screening studies performed by IEEE working group J18 for an example power system. Areas of future study will also be highlighted.

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

Transient immunity assessment of wind and solar parks773

Abstract
Abstract
Inverter-base Resources (IBRs), such as solar photovoltaic (PV) and wind parks are subject to transients which may cause more issues as compare to traditional generation due to the colle... see morector grid and the geographical spread between converters. In this webinar, we present several challenges which may be faced by planners and park developers:
- Transient immunity against utility-owned capacitor bank switching. Assessment of IEEE Std 1547-2018.
- Ferroresonance after open-phase faults.
- Temporary overvoltage (TOV) in a PV parks after a phase-to-ground fault
Events and EMTP simulations will be described and analysed during the webinar.
This work was performed with the collaboration of Bob Arritt, EPRI and Chest Li, Hydro One
