Research on Short-term Fine Operation of Hydropower Station Based on Optimal Flow Allocation
In the previous research on hydropower station scheduling,due to the different application scenarios of the"determining electricity by water"and"determining water by electricity"modes,short-term optimal dispatch or real-time optimal dispatch is usually used for hydropower stations alone.When short-term or real-time dispatching is carried out separately,due to the different output calculation methods of the two,the solution of the output in each period in the scheduling process is different,and it is difficult to ensure the consistency and optimality of the short-term scheduling and real-time scheduling output calculation.Therefore,this study,by building an optimal flow allocation model,couples the short-term dispatch model and the optimal flow allocation of units,to obtain the theoretical optimal output within the cal-culation period,so as to realize the coupling of power station and unit at the short-term and real-time scheduling level.Taking the power generation scheduling of Aertashi Reservoir as an example,through calculation,it is found that the power generation of the proposed method during the dispatch period is increased by nearly 9%,which is an additional 5.5%compared with the traditional optimized dispatch method,which greatly improves the economic benefits of the hy-dropower station.
