Clean energy active coordination control method by considering vibration interval of hydroelectric generating set

Abstract

The invention discloses a clean energy active coordination control method by considering a vibration interval of a hydroelectric generating set, which is applied to a control system of a plurality ofclean energy power stations of a power grid power flow section, wherein the plurality of clean energy power stations comprise wind power, photovoltaic and hydropower stations, and the control system comprises a coordination instruction. The coordination control method comprises the steps of: establishing an active power coordination control model of the plurality of clean energy power stations; constructing an operation state partition according to the consumption space and the load rate of the power flow section; performing coordination instruction optimization based on the active power coordination control model and the operation state partition; and performing coordination control on the plurality of clean energy power stations based on the optimized coordination instruction, and avoiding wind and light abandonment and operation of the hydroelectric generating set in a vibration interval through a partition coordination control mode.

Description

technical field [0001] The invention relates to the field of power system scheduling operation and control, in particular to a clean energy active power coordination control method considering the vibration interval of a hydroelectric unit. Background technique [0002] Considering factors such as environmental protection, the country vigorously develops clean energy power generation. With the rapid increase in the scale of new energy power generation, a large number of new energy power stations participate in the power supply system, and the number of clean energy sources participating in the same power flow section is gradually increasing. Due to The power generation characteristics of new energy power plants such as wind power and photovoltaic power plants are random, fluctuating and intermittent, and the current situation of peak-shaving resources in the power grid and insufficient transmission channel capacity have led to serious problems of abandoning wind and light for...

AI Technical Summary

Problems solved by technology

[0003] The existing technical achievements do not comprehensively consider the constraints of grid security and stability, hydropower vibration interval constraints, wind and wind independent constraints, and peak shaving constraints. When the load rates of each constraint are different, the upper and lower limits of the command of the new energy power station are not taken into account. New energy abandonment of wind and light is serious, and the capacity of the power grid is not fully utilized
