Systems and methods for sequential power system model parameter estimation

Abstract

A system for sequential power system model calibration is provided. The system includes a computing device in communication with at least one sensor monitoring a power system. The computing device includes at least one processor in communication with at least one memory. The at least one processor is programmed to store a model of a device. The model includes a plurality of parameters. The at least one processor is also programmed to receive a plurality of events associated with the device, filter the plurality of events to generate a plurality of unique events, sequentially analyze the plurality of unique events to determine a set of calibrated parameters for the model, and update the model to include the set of calibrated parameters.

Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of priority to U.S. Provisional Patent Application No. 62 / 833,492, filed Apr. 12, 2019, entitled “SYSTEMS AND METHODS FOR SEQUENTIAL POWER SYSTEM MODEL PARAMETER ESTIMATION,” the entire contents and disclosure of which are incorporated by reference in its entirety.BACKGROUND

[0002] The field of the invention relates generally to sequential power system model parameter estimation, and more particularly, to a system for modeling sequential power systems based on multiple events.

[0003] During 1996 Western System Coordinating Council (WSCC) blackout, the planning studies conducted using dynamic models had predicted stable system operation, whereas the real system became unstable in a few minutes with severe swings. To ensure the models represent the real system accurately, North American Electric Reliability Coordinator (NERC) requires generators above 20 MVA to be tested every 5 years or 10 years (depending o...

Embodiment Construction

[0029]In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of embodiments. However, it will be understood by those of ordinary skill in the art that the embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the embodiments.

[0030]One or more specific embodiments are described below. In an effort to provide a concise description of these embodiments, all features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another.
