Hello! I'm Raymund

I am a passionate electrical engineer and fitness fanatic

After graduating from ERCOT's EDP program, I've started working as an Operations Analysis Engineer specializing in analyzing renewable generator performance and renewable forecasting.

Outside of work, you can probably find me climbing at Crux Central.

Operations Analysis Engineer

Electric Reliability Council of Texas (ERCOT)

  • Investigate and resolve renewable generation telemetry and performance issues that occurred in real-time.

  • Evaluated new renewable generator dispatch technique that would result in improved interface flow control and efficiency.

  • Created web-based displays using javascript and html to visualize ERCOT's net load forecast and impact of icing on wind generation.

  • Defended proposed changes to protocol language about evaluating real time ancillary service shortages at stakeholder meetings using retroactive analysis.

EDP Engineer


Electric Reliability Council of Texas (ERCOT)

  • Developed Python tool to automatically compare and validate power flow solutions of GE Alstom EMS and PowerWorld

  • Created web display using SAS data queries describing the relationship between reliability metrics and a component of a system-wide price adder

  • Developed VBA tool to identify late outage extensions

  • Evaluated ride-through and exciter performance of wind turbines with dynamic simulations in PSS/E

2018 Summer


PJM Interconnection 

  • Developed PJM's GMD model using PSS/E and Python, meeting NERC TPL-007 compliance deadline

  • Validated accuracy of model using field measurements and data visualization


Research Assistant

Teaching Assistant

Texas A&M University

  • Used PowerWorld to simulate how the effect of geomagnetic storms or EMPs on a power system vary with different earth conductivity models

  • Developed a MATLAB tool to automate calculating the magnitude of an EMP, caused by a high altitude nuclear blast, at any latitude and longitude.

  • Teaching Assistant for Power Systems Operations and Control

Research Paper Publications

  • Electric Grid Impacts of E3 HEMP With Detailed Ground Modeling (1st Author, Accepted to IEEE Trans. of Power Systems)

  • Comparing the Impact of HEMP Electric Field Waveforms on a Synthetic Grid (1st Author, Accepted to NAPS 2018)

  • Impact of 1D vs 3D Earth Conductivity Based Electric Fields on GIC (3rd Author, Accepted to ISGT 2018)

Electrical Maintenance 

and Reliability Engineer

Ascend Performance Materials

  •  Managed multidisciplinary project team of electrical, chemical and mechanical engineers who installed a 1250HP cooling tower motor on schedule and under budget

  •  Composed detailed electrical switching procedures, lock out plans, and executed maintenance work on time despite unexpected changes to the scope of the plant shut down

  • Replaced 20kVA UPS system while maintaining critical loads by developing detailed drawing packages, installation procedures and electrical switching procedures

  • Performed investigation of variable frequency drive (VFD) failure by reviewing evidence, interviewing operators, and researching technical documents. Revealed s systemic problem with the way VFDs were grounded all throughout the production unit.

  • Simplified site-wide lightning protection strategy by reducing number of arresters by 50%

Dynamic Simulation of EMP

Dynamic Simulation of HEMP

This video is a side-by-side comparison of two dynamic studies in which an HEMP was applied to a 10,000 bus synthetic grid. The only difference between the two simulations is the ground conductivity model used to calculate the HEMP electric field. The video clearly shows that the uniform model yields more severe impacts to the grid's voltage stability.

The HEMP electric fields used in this video were calculated using a tool I developed using MATLAB.

At any point of time in my life, I have been obsessed with at least one sport.  My major obsessions have been taekwondo, running, basketball, and most recently, rock climbing.  My involvement in these sports has shaped my mentality of continual self-improvement in all aspects of my life.
