Abstract
The large-scale integration of new energy into the grid has caused increased frequency fluctuations in the grid,making the frequency modulation task of thermal power units heavy and frequent,exacerbating the aging of the unit,flywheel energy storage assisted thermal power unit frequency modulation can improve the frequency modulation performance of the unit.The principle of primary frequency modulation of flywheel energy storage auxiliary unit is discussed,and the flywheel energy storage's frequency modulation characteristics are analyzed.Combining with the world's largest capacity flywheel energy storage,the full power control strategy for primary frequency modulation of flywheel energy storage auxiliary units is proposed,and applied to the shakedown test of China's first set of flywheel energy storage auxiliary thermal power unit's primary frequency modulation to verify the effectiveness of the control strategy.The field test results show that,the primary frequency modulation performance of the flywheel energy storage auxiliary thermal power unit is good.After the proposed primary frequency modulation strategy is adopted,the qualification rate of the primary frequency modulation action of the unit increases by 21.26%,and the integral electricity contribution index of the primary frequency modulation increases by 3.45 times.The primary frequency modulation mode of flywheel energy storage auxiliary thermal power unit has certain guiding significance to solve such problems.
