Update: Power2Peer Demonstrates Cloud-Based Software Defined Network Control with Battery Backup

January 24, 2019

Power2Peer Reaches Another Important Milestone

A team of engineers under the guidance and supervision of Dr. Nish Sonwalkar (ScD, MIT), founder and chief scientist of Power2Peer, has successfully completed the demonstration and efficacy of Power2Peer’s Software Defined Network (SDN) controller platform.

This technology will allow Power2Peer to control solar power generation systems remotely via cloud computing systems with Wi-Fi connectivity. Currently, control systems use software embedded in the hardware on site to control the flow of electricity.  But with this latest innovation from the Power2Peer engineering team, power systems can be controlled with cloud computing architecture complete a battery back-up system (see Figure 1).


As shown in Figure 1, the four panel solar system is connected to 12 loads representing 12 households powered by the solar panels. The system sends information to the cloud-based controller. When there is a failure in the system, the software sends messages to hardware relays in order to reconfigure the electric network, ensuring that alls twelve households all receive power from the available solar panels.  If all panels fail to generate electricity, then the battery backup is used to power all 12 households until the electrical supply is restored.  The battery backup also supplies power to the households at night when there is no sunlight.

As shown in Figure 2, this is all accomplished from the cloud. The Software Defined Network Controller has the AI logic to make decisions about which relays need to be activated to ensure electricity is always available to each household.  This kind of resilient solar power system is thus called a self-healing power system.


With this development Power2Peer takes a critical step towards the creation of a resilient energy marketplace that will ensure uninterrupted power supply to consumers.
