Demonstrations

RIAPS at LF Energy Summit

RIAPS was demonstrated on Wednesday, October 24, 2018 at the first ever LF Energy Summit was held in Edinburgh, UK. This presentation describes the RIAPS platform and demonstrates how it can be utilized to run a simple application. Also shown is a microgrid resynchronization application created with this platform in collaboration with the NSF FREEDM ERC at North Carolina State University.

Nested Microgrid Reconfiguration Demonstration
This video shows the a distributed secondary control for a nested Microgrid reconfiguration application on the RIAPS platform by North Carolina State University NSF FREEDM ERC team. The application achieved seamless transition for microgrid reconfiguration while maintaining the voltage unbalance factor at critical loads within acceptable range. The system utilized an Opal-RT real-time simulator, TI F28377S DSP, TI Beaglebone Black single board computers and a controlling application on a Linux machine.

Timed Distributed Coordination Service
This application demonstrates the Timed Distributed Coordination services available on the RIAPS platform. This was presented at the 2018 ARPA-E Energy Innovation Summit by the Vanderbilt University team. This service enables group formation, leader election, consensus on an action and future execution time, along with execution of the action precisely at the same time across the group members.

Initial Microgrid Application (2017)
Demonstrates how a distributed Microgrid Re-synchronization application can be implemented running on four RIAPS nodes
  • One node is used to capture the data from the system
  • Three nodes are connected to a real-time power grid simulator

Initial Transactive Energy Application (2017)
Demo Abstract
This application demonstrates two distributed RIAPS nodes in a network interacting with a distribution level power system simulator (GridLAB-D) and each other. Each RIAPS node is hosting a different application actor, one is a Generator Actor and the other a Consumer Actor. The Generator Actor is setting the price of the energy based on the consumer usage, while the Consumer Actor is adjusting their heating setpoint based on the price.

Alternate Application - Adaptive Intersection Management
Demo Paper
The RIAPS platform provides a versatile framework to address other distributed application problems, such as intersection management in a smart city environment. This example utilizes a city simulation where the traffic lights in each intersection are controlled by a traffic controller application implemented with the RIAPS platform running on embedded single board computers. The simulation sends simulated “sensor data” to the intersection controllers consisting of the traffic density for the incoming road segments, as well as the current state of the traffic lights. Each intersection controller shares this information with its neighboring controllers, and each uses the information to estimate the traffic incoming on each segment. This information is used to change the state of the traffic light with the objective of improving the flow of traffic. The testbed utilizes 4 RIAPS nodes (using Beaglebone Black) connected through an Ethernet switch to a computer running a city simulation video game.
