Description

Control method for wind power and conventional energy networking based on frequency modulation task transfer

Technical Field

The invention belongs to the technical field of automatic control of power systems, and relates to a control method for wind power and conventional energy networking based on frequency modulation task transfer.

Background

With the implementation of new energy strategies, the proportion of wind power is continuously increased, but wind power generation mainly depends on weather resources which cannot be regulated and stored, has strong randomness and volatility characteristics, seriously threatens the safety of a power grid, and is even liked to be 'garbage power' in partial occasions due to the inverse peak-load regulation characteristic that the power generation peak valley and the power consumption peak valley are completely opposite.

Meanwhile, conventional power supply types represented by conventional hydropower stations and thermal power stations exist, the conventional power supplies take combustion heat energy and hydraulic potential energy of coal and natural gas as motive power sources of generators, so that the conventional power supplies have good adjustability and storability (depending on coal storage amount, gas storage amount or water storage capacity) compared with wind power, and are core supporting power supplies of power systems until now, but water and thermal power still have obvious performance difference in the adjusting process of primary frequency modulation and secondary frequency modulation due to different adjusting mechanisms, the comprehensive performance is that the adjusting performance of the secondary frequency modulation of the hydropower is obviously superior to that of the thermal power, and the adjusting performance of the primary frequency modulation is obviously inferior to that of the thermal power.

The unbalance between the power generation power and the power consumption of the power grid is represented by the deviation between the power grid frequency and the rated frequency (50Hz), when the deviation between the power grid frequency and the rated frequency exceeds a threshold value, the output active power of each grid-connected power station in a control range is regulated by scheduling, the power generation power and the power consumption of the power grid are restored to a balanced state, the difference between the power grid frequency and the rated frequency is ensured to be in an allowable range, and the whole process is called secondary frequency modulation. The secondary frequency modulation comprises the following steps: 1) the dispatching mechanism calculates the generating power variation required for enabling the power grid frequency to return to the rated frequency according to the power grid frequency deviation and the power grid frequency-power sensitivity coefficient; 2) the dispatching corrects the active power set value of each grid-connected power station in the control area according to the calculation result, and sends a power regulation instruction; 3) after each power station receives the new active power set value, the AGC distributes the total active power set value of the power station to each unit controlled by the AGC; 4) and the active power control system of each unit performs closed-loop feedback regulation on the active power of the unit according to the new single-unit active power set value.

When the deviation of the power grid frequency and the rated frequency exceeds a primary frequency modulation threshold value (most power grids in China are hydroelectric power 0.05Hz and thermal power 0.03Hz), the active power of each unit is adjusted by each unit speed regulator system according to a preset 'frequency-power' adjustment coefficient so as to make up the imbalance between the generating power and the consumed power of the power grid to a certain extent. Compared with secondary frequency modulation, because a unified control center is not provided for performing coordinated control on each unit participating in primary frequency modulation and is related to a calculation mechanism of an adjustment amount, the primary frequency modulation cannot enable the frequency of a power grid to be completely recovered to a rated frequency, so that the primary frequency modulation is also called as differential adjustment, but the primary frequency modulation has the advantages that: 1) because a uniform control center is not arranged, the risk of complete failure like secondary frequency modulation (for example, abnormal exit of a secondary frequency modulation function module is scheduled) is avoided, and thus extremely high overall reliability is obtained; 2) the regulating instruction is directly calculated by the unit, and processes of scheduling calculation, instruction transmission, AGC distribution of a power station and the like of secondary frequency modulation are omitted, so that the response speed to the power grid frequency abnormality is far higher than that of the secondary frequency modulation.

Wind power and a conventional power supply are used as an organic whole, and a power regulation task is executed aiming at the dynamic balance of consumption and supply of a power system. Compared with a single wind power supply or a single conventional power supply, the wind power supply has the advantages that the wind power supply has the adjusting capacity equivalent to the conventional power supply in scale, and meanwhile, under the condition of abundant wind power, the active power output of the conventional power supply can be correspondingly reduced, and the energy-saving aims of water storage and coal saving are achieved; however, the limitation is that the complementary integrated power supply of "wind power + conventional power supply" also has the aeipathia of the conventional power supply in terms of frequency adjustment, that is, "wind power + hydroelectric power" has the performance disadvantage of primary frequency modulation as well as hydroelectric power, and "wind power + fossil power" has the performance disadvantage of secondary frequency modulation as well as fossil power, and because of the inherent active power adjustment delay of the conventional power supply (no matter hydroelectric power or fossil power), "wind power + conventional energy" can only be suppressed to a certain extent and cannot solve the problem of random fluctuation of the output power of the wind power supply, in extreme cases, when the output power of the wind power supply oscillates in a manner of approximate simple harmonic, the conventional power supply may even have the resonant adjustment of the active power due to the adjustment delay, thereby exacerbating the overall output power oscillation of the complementary integrated power supply of "wind power + conventional energy".
