摘要：

Stabilizing discharge flow fluctuation by anti-regulating reservoir will provide support for the upstream hydropower station for deep peak-regulating of power grid, and will make for the consumption of high penetration intermittent renewable energy, as well as increases anti-regulating hydropower station output by increase upstream power station discharge flow, and then achieving win-win effect, In this paper, a coordinated scheduling model about upstream peak-regulating station and downstream anti-regulating reservoir in cascade hydropower is established, which include day-ahead scheduling layer and real time scheduling layer. In day-ahead scheduling, the peak-regulating output of upstream hydropower station will be priority arranged, and the application of moving average filtering method will stabilizing the unsteady water flow about upstream peak-reregulating, which will realizing the stable discharge of anti-regulating reservoir under constraints of the reservoir water level and the downstream river section flow, adjustting filter parameters and day-head output plan in order to avoid the damage of constraints. Real-time scheduling focuses on tracking and timely correction of the larger deviation between real-time operation and day-ahead plant, ensure the smooth implementation of day-ahead plant. Finally a cascade hydropower station for example, by MATLAB program simulation shows that: the proposed method has strong practicability of combined operation about peak-regulating andanti-regulating reservoir. © 2017, Power System Technology Press.
