Embodiment Construction
[0064] A short-term power prediction method for small hydropower classification, which includes:
[0065] Step 1. Collect regional run-of-river small hydropower and non-run-off hydropower data;
[0066] The run-off small hydropower data information collected in step 1 includes meteorological data, output data, and start-up and shutdown data. The meteorological data should include temperature, air pressure, humidity, wind direction, wind speed, and rainfall data in the area where the run-off small hydropower is located. The data information of the non-runoff hydropower includes meteorological data, output data, outbound water volume, start-up and shutdown data, and the meteorological data should include temperature, air pressure, humidity, wind direction, wind speed, rainfall data and The medium and long-term power generation plan of non-river small hydropower and the peak and valley electricity price data of the regional power grid.
[0067] Geographic location data should in...

The invention discloses a method for power dispatching by using mini hydropower classification short-period power prediction. The method includes the steps of 1) collecting regional mini hydropower data information, 2) conducting short-period power prediction for radial flow type mini hydropower at j-moment, 3) conducting short-period power prediction for non-radial flow type mini hydropower at j-moment, 4) obtaining the regional mini hydropower short period power predicted value according to the short period power predicted values of regional radial flow type mini hydropower and non-radial flow type mini hydro power at j-moment, 5) adding the regional mini hydropower short period power predicted value in current power generating plan at the j-moment of a prediction day, 6) determining whether the regional mini hydropower short period power predicted value passes the power transmission section safety check, if not entering into 7) and if yes entering into 8), 7) adjusting the mini hydropower output, and 8) compiling and sending down the current power generating plan containing the mini hydropower short period power predicted value for execution. The method solves the technical problem that mini hydropower installation greatly threatens the safety and operation stability of a power grid in the prior art.
Description
technical field [0001] The invention belongs to the technical field of small hydropower dispatching, and in particular relates to a method for participating in grid dispatching by utilizing classified short-term power prediction of small hydropower. Background technique [0002] As a green renewable energy recognized by the clean development mechanism, small hydropower has the largest reserves of hydropower resources in the world. At the same time, it has the advantages of small scale, no pollution, promotion of local economic construction, short start-up and shutdown time, and flexible operation arrangements. , has brought a lot of positive significance to the safe, stable, high-quality and economical operation of the power grid, especially the regional power grid, stable and reliable continuous power supply, and operation mode arrangements. Although the installed capacity of small hydropower is generally small, with the continuous increase of installed capacity of small hy...
