Title:
APPLICATION METHOD FOR HYDROELECTRIC-PHOTOVOLTAIC COMPLEMENTARY SCHEDULING GRAPH OF CLEAN ENERGY BASE
Document Type and Number:
WIPO Patent Application WO/2024/032483
Kind Code:
A1
Abstract:
Disclosed in the present invention is an application method for a hydroelectric-photovoltaic complementary scheduling graph of a clean energy base. The method comprises: dividing a hydroelectric-photovoltaic complementary scheduling graph into two scheduling sub-graphs according to a runoff guarantee rate and a critical guarantee rate within a scheduling period, wherein each scheduling sub-graph is divided into different scheduling areas by means of scheduling lines, and each scheduling area has hydroelectric output information; predicting the runoff within the scheduling period, and a predicted photovoltaic output; selecting a corresponding scheduling sub-graph according to the runoff guarantee rate, determining a hydroelectric output of a reservoir in the current month according to the water level of the reservoir at the beginning of the current month and a scheduling area where the water level is located, and obtaining the water level of the reservoir at the end of the current month by means of carrying out runoff calculation until the calculation of the hydroelectric outputs and water levels of the reservoir in all months within the scheduling period is completed; and obtaining a long-term hydroelectric output process and a long-term reservoir water level process in a clean energy base, and calculating a hydroelectric generation guarantee rate, thereby completing scheduling. By means of the present invention, the grid-connected consumption of photovoltaic power is also taken into consideration during a reservoir scheduling process, such that the consumption level of photovoltaic power is improved on the basis of guaranteeing a hydroelectric output.
