Systems and methods for managing an in-person transaction process are provided. In example embodiments, a network system receives, from a first user device, information regarding a service or an item. Using the received information, the network system generates an unpublished listing and associates the unpublished listing with a session identifier. The unpublished listing is temporarily stored to a datastore. The network system then generates a scannable code that provides a uniform resource identifier (URI) associated with the session identifier. The scannable code is presented on the first user device, whereby the scannable code can be scanned by a second user device to access, via the URI, a transaction user interface associated with the session identifier. In response to a request to access the transaction user interface triggered by the second user device scanning the scannable code, the transaction user interface is displayed on the second user device.

Systems and methods for processing measurement data in an electric power system include acquiring the measurement data by a phasor measurement unit (PMU) coupled to a line of the electric power system, and inputting a plurality of the measurement data within a predetermined time window into a K-nearest neighbor (KNN) for identifying bad data among the plurality of the measurement data, wherein when one of the plurality of measurement data contains a bad datum, the machine learning module sends the bad datum to a denoising autoencoder module for correcting the bad datum, wherein the denoising autoencoder module outputs a corrected part corresponding to the bad datum, and when one of the plurality of measurement data contains no bad datum, the machine learning module bypasses the denoising autoencoder module and outputs the one of the plurality of measurement data as an untouched part.

Systems and methods of bad data identification and recovery for electric power systems

A method for managing a power load of a grid includes performing a statistic-based distribution estimation of a composite load model using static and dynamic models with Gibbs sampling; deriving a distribution estimation of load model coefficients; and controlling grid power based on a simulation, a prediction, a stability analysis or a reliability analysis with the load model coefficients.

Bayesian estimation based parameter estimation for composite load model

Systems and methods are disclosed for power management by estimating power contingency of a grid at a cloud control center; performing decentralized real-time measurement and making local decisions at one more computer controlled outlets connected to the grid; and aggregating distributed loads to provide emergency frequency support to the grid.

Adaptive method for aggregation of distributed loads to provide emergency frequency support

Systems and methods are disclosed to control the power grid frequency by capturing the frequency change using an extended Kalman filter method with the distributed smart outlet devices at the low-voltage distribution level; and locally control the relay that provides power to the appliance by comparing the captured frequency with the threshold sent from the cloud control center.
