With the expansion and enhancement of the power transmission network, short-circuit current (SCC) has become a major concern in grid operations. While transmission switching is one effective solution to reduce the SCC without investing in additional equipment, switching lines could threaten system N-1 security. To find an efficient, and secure, yet economic switching solution, this paper proposes...
This paper introduces a dynamic multiplier-based Lagrangian relaxation approach for the solution to multi-area economic dispatch (MAED) in a fully decentralized manner. Dynamic multipliers refer to the multipliers associated with power balance equations at tie-line buses in each area. Dynamic multipliers can be approximated as linear functions of tie-line power exports via sensitivity analysis and...
The equivalent modeling method is extensively used in the area of power system optimization. The thermal power system can be simplified into an equivalent thermal unit in the studies where the performance of individual units is not the focus. Conventionally, the equivalent ramp rate for the equivalent thermal unit is the summation of each unit's ramp rate. However, the equivalent ramp rate relies...
