Summary:  The MRI instrument suite development enables transformative research in sensors and machine learning for energy applications.  The project will unleash creativity in integrating embedded electronics and machine learning to monitor and control solar arrays. Societal outcomes of research enabled by this MRI will have an impact on environmental initiatives by increasing efficiency in solar power generation. Results and patented technology will influence emerging international standards of utility-scale PV arrays. The shared research instrument will have a broader impact as it is an enabler for developing new integrated sensors and machine learning technology that can be ported in several other sustainability applications. The development of this instrument suite will greatly benefit a large number of graduate and undergraduate students taking courses in machine learning, solar systems, signal processing, and artificial intelligence.

 

MRI Equipment Acquisitions

The project involves several equipment acquisitions including:

 a) Prototype Components; Texas Instruments Data Conversion 20MHz, Power management Kits to enable measurements of solar array voltages and other parameters.

b) Skyline Cameras with computer interface; These will provide images and video sequences for cloud monitoring and shading prediction.

c) Programmable Solar Load. These will enable us to build a configurable resistive load to run long term experiments with various load conditions.

d) Solar Load Simulator. This is an instrument that will assist in making precise measurements for a programmable solar load.

e) Grid Simulator. This simulator will enable simulating various grid conditions. All experiments for fault detection and shading will be examined with regard to their effect on the grid.

f) Solar Array Simulator; This programmable simulator will enable various real-time experiments including those planned for inverter transient control.

g) Solar I-V Curve Tracer; This will enable measuring I-V curves for solar panels for various solar array experiments including fault detection, shading, soling experiments.

h) Irradiance Sensors; Three sensors that will enable obtaining irradiance measurements to fuse together with skyline camera info and predict cloud and shading conditions.

i) Programmable Inverters; Inverters will enable the team to assess and control transient effects. The inverters will have an interface for configuration, measurement, and control.

j) Deep Learning Computer and Server with 32GB NVIDIA cards;  To conduct training of ML algorithms and Deep Neural networks we requite computers equipped with GPUs.
