Preliminary Agenda


July 21, 2022

8:00 - 9:00 | Meet & Greet

The EMTP® development team is introduced, along with the program schedule and a brief history on EMTP®. Also, attendees will have the chance to learn about upcoming software developments, provide feedback to developers, request updated modules, features, and discuss EMTP-related issues.

This presentation covers the development of a generic grid-forming (GFM) inverter model in EMTP focusing on the simulation aspect. A general description of the model is given, followed by several case studies.

This presentation will discuss why the induction of AC lines near the DC line needs to be quantified and the challenge associated with having multiple AC circuits from different grids. It will also expose how batch simulations with Parametric Studio saved time for this case, as well as for studying the fault current at different locations.

EMTP's import tool function will be used to convert a PSS/E grid to EMTP. Transient studies are conducted for 100 breaker closing instances, along with statistical analysis and worst-case scenarios.

During this presentation, a few examples of the use of EMTP in transmission level planning research will be discussed.

12:00 - 13:30 | Lunch

This presentation covers the issue of the current Zero-Missing Phenomenon (ZMP), defined as a current not crossing zero value during several cycles because of the slowly decaying DC component.

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 this 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.

This work presents a brief introduction to SSCIs, followed by parametric studies involving three PLL models. Additional key findings during SSCI screening studies performed by IEEE working group J18 will be also presented.

This presentation shows a tool developed in EMTP to automatically determine the optimal model settings to fit an IBR recorded behavior. The optimization process uses a particles swarm optimization algorithm, which is an optimization technique used in artificial intelligence. The tool can estimate a mix of model parameter values.

15:30 - 16:00 | Coffee Break

The presentation will describe the studies performed to determine the expected performances of a VSC HVDC link that will become the main power source for an islanded network. The study includes the use of a full VSC EMTP model (generic) and also the interoperability with weak networks and wind farms, on both sides of the link.

This presentation shows a summary of EMT modelling experiences of PV power plants according to different grid operator requirements. Depending on the study that is demanded, aggregated or disaggregated representation is needed to characterize the internal network, a simplified method for obtaining an electric equivalent is presented.

Throughout this case study, you will learn about the California Oregon Transmission Project (COTP) and its goal of replacing the existing fixed series capacitor banks (FSCBs) with new equipment.
