What's New in Simplex Nodal

2.3

May 22, 2020

Tidied up the displays so they look good on iPhone 11 and iPad (and prepared for macOS... yes, there is now a Mac version).

User reviews

Intuitive interface with great depth and portability

I've used the app to quickly put together ad hoc models of the NZ electricity transmission network. Using the Simplex Nodal example models it's interesting to play with the boundary between the financial market and electrical security to see what really determined prices.

It's useful for my Operations Research uni studies to have a quick reference to remind me of the concepts. I wonder how it would be useful for electrical engineers and sparkys?

The results and model can be emailed out. I've taken them into work and run them through the commercial solvers and the results line up. Reading through the online user guide you can see that it covers all the significant inputs for a working transmission system like optimising energy and reserves and let's you customise even how the electrical losses are calculated.
