Abstract
- A feasible scheduling strategy of AGC capacity has been proposed. A mathematical model of AGC operating expense is built firstly, which include fuel costs that are incurred when units are operating on basic point, capacity costs that are associated with AGC capacity reserved, and the AGC adjustment costs of units. Then, based on the model, we construct the Lagrangian function and deduce the shadow prices of AGC electricity of scheduled units and the equilibrium of the shadow prices. Last, a feasible scheduling strategy of AGC capacity is designed. The numerical experiment indicates that the strategy can allocate real-time scheduled AGC electricity fairly and reasonably, which can ensure the system perform reliably and securely, and be economical simultaneously.
