Abstract:

In the existing load distribution solutions, there is little consideration on the rapid response of units to network speed and on the small change strategy of units. Moreover, the contradiction between the speed and the economy in the factory-level distribution has not been solved yet. To deal these problems, this paper proposes an algorithm based on the improved freworks algorithm, which changes the load boundary and climbs constraint adaptively, to dynamically achieve rapid response of load changes. At the same time, the algorithm sorts the units according to a predetermined priority order to achieve the minimum unit load changes under the certain constraints when unit load changing occurs. Finally, it introduces a switching mechanism to solve the contradiction among the lowest coal-consumption, quick adjustment and the little unit-change with flexible optimization. The paper presents a specifc algorithm of plant-level real-time online optimization of load distribution and conducts the simulation for an example with four units. The simulation results show the effectiveness of the algorithm.

Key words: load real time and online dispatch, minimum unit change, flexibility optimization, improved frework algorithm, fast regulation
