In order to satisfy the rapid load adjustment requirements of coal-fired units in the situation of alternate electrical power system, the optimal load dispatch in power plant prevents frequent coal mills operation based on speediness is studied in this paper. Firstly, the mathematical formulation of PPLD with POZs based on speediness is presented, and then strategy of POZs constraints and improved ga-ts algorithm to find the optimal solution are introduced. Finally, through simulation the effectiveness of the mathematical formulation of PPLD with POZs based on speediness is tested. The simulation result show: when the load is distributed with the economy and speediness as target separately, the distribution results are significantly different, and the load adjustment time with the aim of speediness is obviously shorter than that of economy. It shows that the optimal load dispatch in power plants based on speediness is an effective control strategy for the rapid load adjustment of units, which can contribute to the further improvement of the operating flexibility of coal-fired units in the new energy power system situation.

Minimum mills and Prohibited Operating Zones(POZ) are introduced as constraints for thermal power plant load re-dispatching. New feasible solutions searching method based on possible solution spaces combination, and an improved Genetic-Tabu algorithm is proposed. Simulations are done on a simulation example with 8 thermal power units, and results show righteous and effectiveness of the proposed work.
