Abstract

Due to cross-level hierarchical control is usually adopted in China Power Grid, the regulating of direct-dispatching generators would have impacts on the calculation of ACE of the province, in which direct-dispatching generators locate. Closed area method that direct-dispatching generators are excluded from the provincial control area has been presented to solve the impact. However, there are not adequate theoretical explanations aimed at the method. This paper will show a theoretical proof of the necessity and effectiveness of the closed area method in detail with area control model. Then digital simulation on how closed method is applied in actual power grids will be carried out with load frequency control model, the result shows that closed area method significantly reduces the impacts on ACE of provincial control area from direct-dispatching generations, which proves closed area method to be feasible and effective.
