Research On The Reservoir Scheduling Scheme In The Design Of The Yilqiang Casca De Hydropower Station

Reservoir optimal operation has been a hot issue of water resources research,but no method has been perfect so far,so the research of reservoir optimal operation method will continue to be thorough.Under the premise of constantly improving the existing reservoir optimal dispatching system,it is difficult to study thoroughly with an optimization method,so the coupling of the two or several methods will have great development space in the future.Along with the upsurge of the worldwide electricity market reform,China's electricity market reform is steadily advancing,and hydropower market has become the trend of the times.The new market environment to the traditional optimal scheduling of hydro proposed new requirements,how to coordinate the competition and the overall efficiency of cascade hydropower in the market environment has become a problem.In this paper,taking the Yeerqiang River cascade reservoirs as an example,the operation of cascade reservoirs were studied and the following results were obtained:(1)A scheduling particle swarm optimization based Yerqiang River cascade reservoir power generation,taking the Yeerqiang River reservoirs of Aertashi reservoir as an example,the establishment of the water supply on the condition of reservoir operation requirements for reservoir optimization scheduling model and the industry,analyzes the year-end level of multi-year regulating storage reservoir and power generation,to determine the reasonable level the reservoir of Aertashi reservoir interval.(2)Of the total output of the cascade cascade hydropower station and the total annual power generation is analyzed and studied,obtained the optimized cascade compared with the conventional calculation scheme by the group power plant energy index,to effectively improve the power generation efficiency of Yerqiang River cascade reservoirs.(3)In the analysis of power index based cascade reservoir optimal scheduling,to establish reservoir total energy index for the objective function of the reservoir group scheduling graph,and is widely used in Yerqiang River basin reservoir group scheduling.
