Regional hydropower peak regulation limit output estimation optimization method and system

Abstract

The invention discloses a regional hydropower peak regulation limit output estimation optimization method comprising the implementation steps that the limit output total control quantity A of the target region and the basic information of all the hydropower station units are inputted; three rounds of scheduling is performed so that three rounds of scheduling output Ji of any hydropower station unit i is obtained and the total limit output quantity Xi is obtained through summation; the deviation degree Ri of any hydropower station unit i is calculated and the total limit output quantity Xi and / or the limit output starting time is corrected; and the final total limit output quantity of the hydropower station unit and the limit output starting time are issued to each hydropower station unit so as to form a limit output operation instruction. The output of all the hydropower stations can be allocated with reference to strict implementation of the relevant provisions of "openness, fairnessand justice" when water abandoning of the hydropower stations cannot be avoided in case of power grid peak regulation, and the interests of all the hydropower stations are considered through combination of the present situation of all the hydropower stations so that the powerful aid can be provided for the on-duty dispatcher, and "open, fair and just" hydropower dispatching work can be ensured.

Description

technical field [0001] The invention relates to a regional electric peak-shaving limited output scheduling technology, in particular to a regional hydropower peak-shaving limited output estimation optimization method and system. Background technique [0002] As the power grid's low-valley load continues to decrease, the peak-to-valley difference widens, coupled with the rapid development of wind power and solar energy, the contradiction between supply and demand has become more prominent. When small hydropower is abundant and widely distributed in the regional power grid, and affected by other factors such as installed capacity, the hydropower dispatching automation system is not high enough, and water and wind abandonment will become the norm. [0003] When hydropower peak shaving limits output, if only relying on the on-duty dispatcher to control, a large amount of information needs to be collected, which will inevitably consume a lot of computing time on load distribution...

Problems solved by technology

[0003] When hydropower peak shaving limits output, if only relying on the on-duty dispatcher to control, a large amount of information needs to be collected, which will inevitably consume a lot of computing time on load distribution, and the implementation of "three public dispatching" cannot be well guaranteed. Carry out a large amount of data statistical analysis work, which not only increases the labor intensity of the dispatcher, but also lowers the work efficiency
