Abstract: In response to difficulties brought by load variation, load fluctuation, maintenance schedule change of generation and transmission, the mode, model and method of intraday rolling scheduling considering electricity quantity progress constraint are proposed. Based on optimization algorithm, the proposed method can follow the progress of unit power plan accurately through controlling nonlinear balancing target of electricity quantity. This real time rolling mechanism can improve its adaptability to the operation circumstance of power grid, through following changes of both power grid and unit operation conditions, thus the unit electricity quantity plan can be completed accurately by optimizing quantity distribution across time and space dimensions.

Key words: balancing dispatching, dynamic balance, intraday rolling, generation scheduling
