Abstract :
Load shedding is one of the challenging problems in deregulated power systems. This paper studies the load-shedding problem with a dynamic power market model. To establish this model, the characteristic of the power market is analyzed first. Then the parameters in this model are estimated by a recursive weighted least square method. The full model is incorporated into the load shedding problem in a new industry environment. The entire problem is formulated as an optimization problem with differential equations as constraints. A discretization technique is applied to transfer the differential equation into an algebraic equation. Finally, it is solved by mathematical programming. This method is tested on a small and a large system.
