Abstract: One or more embodiments relates to a smart inverter used in a photovoltaic (PV) generation system. In one embodiment, the smart inverter includes a PV control logic device; and at least one low pass filter coupled to and in communication with the at least one PV control logic device.

Abstract: Disclosed herein are methods, systems, and devices for implementing trusted execution environments in the context of data security and data storage. Systems may include a login node comprising one or more processors configured to receive a request from a user, and a secure access port communicatively coupled to the login node and configured to process the request in accordance with one or more data access policies. Systems may further include a secure processing device communicatively coupled to the secure access port and comprising an encrypted portion configured to implement one or more data processing operations associated with the request. The systems may also include an encrypted data repository communicatively coupled to the secure processing device, the encrypted data repository comprising one or more storage devices, and being configured to encrypt and store data in the one or more storage devices.

Abstract: Disclosed herein are methods, systems, and devices for identifying computational operations based on power measurements. Disclosed herein are systems that may include a phase measurement unit configured to generate a first measurement based on a power signal, the first measurement characterizing a phase angle of the power signal. The systems may also include a power measurement unit configured to generate a second measurement based on the power signal, the second measurement characterizing an amplitude of one or more aspects of the power signal. The systems may further include a processing unit configured to identify a computational operation implemented by a target processing device, the identifying of the computational operation being based on a comparison of the first measurement and the second measurement with reference measurements.
