Historically, power distribution systems did not require elaborate monitoring schemes. With radial topology and one-way power flow, it was only necessary to evaluate the envelope of design conditions (i.e., peak loads or fault currents), rather than continually observe the operating state. But the growth of distributed energy resources, such as renewable generation, electric vehicles, and demand response programs, introduces more short-term and unpredicted fluctuations and disturbances [1] . This suggests a need for more refined measurement, given both the challenge of managing increased variability and uncertainty and the presence of a higher level of narrowband and broadband interference and measurement noise. |
