systems such as lithium-ion batteries and/or other advanced energy storage technologies.
This position entails planning, design, modeling, data
collection and analysis of integrated power and energy storage systems and requires
highly detailed and intensive system analysis
Responsibilities of this position include developing
accurate models to assess, design and confirm the addition of energy storage
for renewables integration in grid projects; analyzing hosting capacities in
utility distribution grids and microgrids; evaluation of performance and
interaction of energy storage in the form of batteries, supercapacitors and
traditional thermal based generators in these circuits, and design and analyze
power systems to incorporate and reasonably integrate advanced energy storage
on existing and new grids and microgrids.
The primary duties will include sizing and simulation of
various advanced battery chemistries, advanced energy storage technologies and supercapacitors
and inverters in large systems in an environment of large solar and wind generation.
