A Security-constrained Flexible Demand Scheduling Strategy based on Robust Optimization with Box Set

Driven by the challenge of keeping supply and demand balance all the time, using the flexible demand as an additional participation in the power grid dispatching and decision-making processes is a crucial issue in accommodating wind power. Firstly, flexible demand scheduling cost and the demand response uncertainty cost is considered simultaneously in the objective function. Secondly, the static algorithm was proposed to calculate the amount of flexible demand. On this basis, an optimization flexible demand scheduling model considering network security is established. Finally, the validity and feasibility of the model are analyzed with a numerical test system. The simulation results demonstrate that by employing the proposed strategy the flexible demand can efficiently accommodate wind power with security constraint satisfied.
