Python and Power System Modeling Engineer III

Job DescriptionThe daily duties of the job will be performing EMT PSCAD simulation and python code development.

PSCAD is an EMT simulation software it is the center of the modeling for the PV and BESS systems.

Plants are generally greater than 20MVA.

PSSe software is used to benchmark (overlay) PSCAD results to confirm model matching.

The group is responsible for international grid code compliance.

This is achieved with python wrapping for automation of simulations and python-based plotting and analysis of the results.

You will contribute over time to building an international compliance software that can confirm that new firmware meets requirements and does not introduce bugs.

You will also be exposed to R&D control algorithms in grid forming and grid following PV and BESS, and the latest developments in grid compliance.

Key ResponsibilitiesRun EMT simulations in PSCAD, identify issues with behavior of PV and solar farms control.

Run PSSe dynamic simulation and configure grid scale PV and BESS systems >20MVA.

Run ETAP and other power system solvers for detailed design modeling of PV and BESS inverter systems and compliance.

Develop test sources in EMT and RMS simulation software to test grid scale PV and BESS systems >20MVA.

Develop python code that is used to automatically validate compliance of grid scale Solar Farms and BESS systems.

Be responsible for the compliance analysis python library at a code level, which will include Plotly, matplotlib, numpy and pandas.

Will run EMT (PSCAD) and PSSe (RMS) automations and compliance analysis of CSV results.

Identification and conversion of input file formats to standard arrays, i.e. numpy, pandas.

Time domain data analysis in Python and Python plotting in Plotly and Matplotlib.

Advanced python implementations including: modularity of code, installable libraries, backward compatibility, library version control, etc.

Compliance analysis data processing, for example, full multiple simulation to reporting workflow.

Develop algorithms to process time domain data, for example: rise time, intersection of shapes, signal exceeds 5% bounds.

Experience with EMT or RMS power systems study automation (python wrapping) required.

PSCAD and PSCAR PMR / super-compute experience a plus.

Experience with Solar Farm Dynamic and 2D analysis a plus, like PQ characteristics of solar inverters and aggregate solar farms.

Test compliance of models supporting the optimized design of integrated systems of utility-scale PV, ESS, battery management systems, power converters and their connection to medium voltage power systems.

Collaborate regularly with cross-functional teams to enhance system design, safety, and performance.

Document system designs, modeling results, and testing documentation, providing regular updates on project milestones.

QualificationsBachelor’s or Master’s degree in Electrical Engineering, Computer Engineering or a related field.

Required 1 year of experience in python automation of power systems studies.

Talented graduates considered.

Expertise in engineered applications and solutions for PV/ESS installations.

Understanding of IEEE1547 and IEEE2800, grid codes or other equivalent grid codes for Dynamic and Two-Dimensional assessments of P, Q, I, V characteristics of Solar Farms.

Very strong python skills with a core passion for Python coding.

Strong time domain and two dimensional mathematical skills.

Strong in spatial mathematics.

Preferred experience with power systems simiulations such as PSCAD, PSSe or equivalent EMT and RMS simulation tools.

You bring a passion for renewable energy combined with a love of advanced python automation.

Strong problem-solving, attention to detail, and safety awareness.

Excellent communication and collaboration skills in cross-functional teams.

Ability to thrive in high-pressure environments while ensuring safety and regulatory compliance.
