Description
Technical Field
The invention relates to the technical field of network source coordination control, in particular to a flywheel energy storage compensation device capacity selection method based on a power grid primary frequency modulation examination performance index.
Background
The large-scale utilization of fossil energy brings outstanding problems of resource shortage, environmental pollution, climate change and the like, brings great challenges to social sustainable development, and green energy and comprehensive energy become necessary choices. China is the country with the largest global new energy scale and the fastest development. The wind power grid-connected capacity is increased by 100 times in 10 years, the photovoltaic capacity is increased by 100 times in 5 years, and the installed capacities of wind power and photovoltaic are the first in the world. By 2018, the capacity of the wind and light new energy reaches 3.6 hundred million kilowatts, and accounts for 19 percent of the total installed capacity. China is forming a new pattern of energy development, and the development of green energy revolution, acceleration of energy structure transformation and improvement of energy utilization efficiency become the tasks of the times. The intermittent and fluctuating property of renewable energy power generation and the continuous improvement of permeability provide a serious challenge for the safe and stable operation and scheduling of the existing power system. The fluctuating and intermittent nature of new energy sources requires that the system must match a certain flexible power source. The power supply structure of China is mainly based on thermal power, the proportion reaches about 60%, particularly the proportion in the 'three north' area reaches 70%, the power supply is flexibly adjusted to be 6% in national pumping energy storage, fuel gas and the like, and the proportion in the 'three north' area is less than 4%.
The energy storage technology is used as an effective means for improving the consumption capacity of new energy, network source coordinated operation can be realized in multiple time scales such as millisecond level, second level, minute level and the like, and the stable operation capacity of a power grid under the condition of high-proportion access of the new energy is improved. At present, an energy storage technology is applied to the field of frequency modulation and peak shaving in the power industry, but generally, chemical energy storage is adopted, such as lead-acid batteries, lithium iron phosphate batteries and the like, and the problems of limited charging and discharging times and the like exist, so that the energy storage technology is generally applied to AGC (automatic generation control) and belongs to the field of secondary frequency modulation. Flywheel energy storage (abbreviated as FES) is an advanced physical energy storage technology from aerospace, and is an energy storage mode that a Flywheel is driven by electric energy to rotate at a high speed, the electric energy is converted into mechanical energy, a motor is dragged by inertia of the Flywheel to generate electricity when needed, and the stored mechanical energy is converted into electric energy to be output (and the Flywheel discharges electricity). Different from other battery technologies, the advantages of the battery are realized on the charge-discharge characteristics of short time, high frequency and high power. The method is mainly applied to the fields of power grid frequency modulation, new energy station grid connection and the like. The flywheel has good energy storage power characteristics and high response speed: millisecond-level high-power charging and discharging and high reliability; high efficiency, maintenance-free: the magnetic suspension support has no friction loss, and the system maintenance period is long; the service life is long: the method is not influenced by repeated deep discharge times, and the service life is generally more than 15 years; green and environment-friendly, and has no pollution: physical energy storage, no chemical substance and no cell later-stage pressure recovery.
The stabilization of the transient frequency of the power grid is mainly realized by a primary frequency modulation function, and for the main components and the main frequency modulation of the current Chinese power grid, the primary frequency modulation of the thermal power generating set is realized by adjusting an air inlet adjusting door of a DEH (digital electric Hydraulic Control System, steam turbine digital electro-Hydraulic Control System), utilizing the heat storage of a boiler, quickly responding to the requirement of the power grid when the power grid is abnormal, stabilizing the power grid frequency, so as to make up the load difference of the power grid, and further maintain the safety of the power grid. The primary frequency modulation of grid-connected power plants of regional power grids of various domestic regional power grids is basically the same, for example, the primary frequency modulation qualification rate of northwest regional power grids is not less than 60%, and the primary frequency modulation qualification rate of Shandong power grids is not less than 70%. As shown in fig. 1, the primary frequency modulation lattice rate is equal to the percentage of the ratio of the actual integral electric quantity of the primary frequency modulation of the unit to the theoretical monthly integral electric quantity, that is, the ratio of the integral area a formed by the theoretical power curve 2 to the integral area B formed by the actual power curve 3.
Compared with AGC, the primary frequency modulation has the characteristics of high action frequency, small action amplitude and the like, so that the quick attenuation of the service life of a battery can be caused by selecting the conventional chemical batteries such as lithium iron phosphate and the like for the primary frequency modulation compensation, and the selection of a flywheel energy storage device for the primary frequency modulation compensation is all practical and feasible schemes. Because the price of the flywheel energy storage device increases along with the increase of the capacity, reasonable compensation capacity selection needs to be carried out according to the performance of primary frequency modulation of the unit.
