Seminar: A Microinverter Based, Self Forming Nanogrid for ON and OFF Grid Applications @ Algonquin College, T-Building, Room T129
May 24 @ 18:00 – 20:00

SPEAKER: Edward Keyes M.Eng, Solantro Semiconductor Corporation

  • Refreshments, Registration and Networking: 18:00
  • Seminar: 18:30 – 20:00.


This talk will disclose a novel, microinverter based, all AC nanogrid architecture using photovoltaic panels and lithium ion battery storage. Much of the nanogrid’s hardware is based on Solantro’s Digital Power Processor chipset. The nanogrid is capable of on-grid and off-grid (islanded) operation with “hot” switching between modes. While in grid tied mode the nanogrid can provide a variety of grid support services to increase the percentage of renewables on the utility grid. These include power smoothing, peak limiting, time shifting of PV generation, and California Rule 21 behaviors. The architecture is granular and highly scaleable. It can be scaled from a single microinverter and battery into the hundreds of devices. In islanded operation the nanogrid is self forming with battery operation controlled by a novel resistive droop control method.

The ease with which we recognize our beloved black cat from hundreds similar to it or read handwritten characters belies the astoundingly complex processes that underlie these common scenarios. Which is why researchers in Machine Learning have been focused on developing a wide range of classification algorithms called classifiers with the goal of tackling these situations with the best possible accuracy. However, most accurate classification models regularly perform like black-boxes, thus neglecting the premise that understanding is an essential part of any learning process, even when the process itself is quite subjective.

In this talk, we will discuss how to exploit information granules in the form of rough sets to design a transparent neural classifier. This model comprises three well-defined steps that are materialized through the Rough Cognitive Networks. In the first step, we discover information granules on the available information using the Rough Set Theory. In the second step, we build a Fuzzy Cognitive Map where input neurons represent the previously discovered granules, while output ones denote the decision classes to be considered. The last step focuses on performing the neural reasoning process using intelligible inclusion equations and causal relations.

Rough Cognitive Networks are capable of computing high-quality predictions (when compared to traditional classifiers) even using a very small network topology. More importantly, the weights are prescriptively established, no further learning is required.

This presentation highlights the industry best practices for measurements on modern
power electronics devices such as SiC and GAN devices. These modern devices introduce new
complexities into power conversion circuits requiring the need for precise circuit timing and higher
sensitivity for gate threshold voltage and timing.
Common measurement pitfalls can be avoided by using differential and floating measurements and
understanding the link between CMRR and signal frequency. Today’s power designs can have
common mode voltages in excess of hundreds or even thousands of volts, while still needing to
measure small differential voltages, this common mode error can be even more severe. Wide
bandgap devices allow switching of higher frequencies, higher voltages and faster rise times, which
requires higher bandwidth scopes and probes with high CMRR. In this presentation, some solutions
for improving the measurement accuracy on SiC and GaN devices during switching will be
