Part 1 - Modeling the New York State Grid in EMTP861

Abstract
PART 1 - The New York state electric grid is transitioning to significantly higher shares of inverter-based resources (IBR) to achieve the clean energy goals of customers and the state. To address th... see moreis challenge, more detailed whole-system modelling in electromagnetic transient (EMT) domain has recently been used for system-level studies including long-term planning and IBR interconnection studies. Along the same line, an EMTP model of the New York State grid was developed and benchmarked in NYPA’s Advanced Grid Innovation Laboratory for Energy (AGILe). This presentation talks about the developed model and its use cases including interconnection studies for High-Voltage Direct Current (HVDC) and renewables.

Simulation of Inductive EM Interference Caused by an HVDC Underground Cable Link on a Railway System853

Abstract
Scope of the presentation is to present results regarding inductive electromagnetic interference (EMI) between a real HVDC link and the nearby communication cables of a railway system under pole-to-gr... see moreound fault conditions.
?he HVDC and the railway system route in parallel at a part of the onshore section of the HVDC link. The inductive EMI on the communication cable arises from magnetic field variation of the high-frequency components contained in the transient response of the fault current, excited by the HVDC link.

Consequently, it is expected that no inductive EMI will occur by the DC current in the case of the HVDC system normal operation (steady-state) either in bipolar or monopolar (current return though the electrode) mode. The induced transient voltages and currents are calculated using the Electromagnetic Transients Program (EMTP-RV).
