Flood Risks of Cyber‐Physical Attacks in a Smart Storm Water System

Water Resources Research, Volume 60, Issue 1, January 2024.
Abstract The rise in smart water technologies has introduced new cybersecurity vulnerabilities for water infrastructures. However, the implications of cyber‐physical attacks on the systems like urban drainage systems remain underexplored. This research delves into this gap, introducing a method to quantify flood risks in the face of cyber‐physical ...

Integrating Demand Response with Unit Commitment in Insular Microgrid considering Forecasting Errors and Battery Storage

International Transactions on Electrical Energy Systems, Volume 2024, Issue 1, 2024.
In this paper, DR programs are integrated with the unit commitment economic dispatch model for a single day to lower total operating costs for an insular microgrid. The proposed model takes into account the forecasting errors associated with wind, solar, and load demands.

Unit commitment with valve-point loading effect [PDF]

, 2014
Valve-point loading affects the input-output characteristics of generating units, bringing the fuel costs nonlinear and nonsmooth. This has been considered in the solution of load dispatch problems, but not in the planning phase of unit commitment.
