Study on Cascade Energy Storage Operation Chart Optimization of Li Xianjiang Basin Based on Progressive Optimal Algorithm

Abstract:

Based on the cascade reservoirs of Li Xianjiang basin, the study of cascade energy storage operation chart was carried out in this paper. Combining the commonly used discriminant method in joint dispatching of cascade reservoirs, the drawing method of energy storage scheduling figure was described detailedly, especially the calculation process of deriving the typical runoff that corresponds to the up and down basic scheduling lines. Considering the power generation reliability was enhanced when implementing the joint operation for cascade reservoirs, the maximum power generation model based on energy storage operation chart was proposed in this paper, and the progressive search method is used in the solving process of the model in a certain range of guaranteed output. In addition, result of the model was further optimized by using Progressive Optimal Algorithm, and comparing the optimized result with the conventional dispatching scheme under the unchanged guaranteed output, the power generation has increased 0.04 million kWh and assurance rate increased 9%.
