Description
Technical Field
The invention relates to the field of peak-shaving frequency modulation application, in particular to a regulation and control system of an electric heat storage device and a use method of the regulation and control system.
Background
In recent years, with the improvement of the living standard of people and the rapid increase of power load, the peak-to-valley difference of the power grid load is gradually increased, and meanwhile, the random, fluctuating and non-schedulable renewable energy sources are connected to the power grid in a large scale, so that the problem of peak regulation of the power grid is more prominent, and a series of difficulties are caused to power scheduling. Power sources and power transmission and distribution equipment in the power system are planned and constructed according to the peak load of a power grid, but the peak load of the power grid has short duration, so that the utilization rate of assets of the power equipment planned and constructed for meeting the peak load requirement is low. The research on solving the peak regulation problem of the power grid and improving the asset utilization rate is an important subject faced by the power grid construction at the present stage.
The power supply structure in China mainly uses thermal power, most conventional thermal power generating units can flexibly adjust the capacity of output which is 50% of the rated capacity, when the load peak-valley difference is lower than the adjustment range of the thermal power generating units, part of small-capacity units are required to start and stop peak regulation or suppress the peak regulation, even more units need to be invested and constructed, and the operation mode of the thermal power generating units is improved to meet the peak regulation requirement, so that the operation cost of the system is greatly increased. According to statistics, in recent years, the peak-valley difference of the Chinese power grid load is 38% -48%, taking the Liaoning power grid as an example, the peak load of the Liaoning power grid in 2011 is 22362MW, the valley load is 12708MW, and the peak-valley difference is 43.2%. The problem of peak shaving is a fundamental problem in the operation of the power grid. The peak regulation technology with rapid start and stop and flexible operation mode meets the application requirements of the power grid peak regulation technology. In the conventional peak regulation technology of an electric power system, compared with a thermal power generating unit, the hydroelectric generating unit is quick in start and stop, flexible in operation mode, and near 100% in peak regulation depth, but the construction of the hydroelectric generating unit is limited by geographical conditions, so that the hydroelectric generating unit cannot be popularized and applied on a large scale.
In order to ensure stable and reliable operation of the power grid and corresponding power quality, the operation frequency of the power grid needs to be controlled. The essence of frequency control is to control the real-time balance of the generated energy and the power consumption in the network, and the frequency control is realized by primary frequency modulation, secondary frequency modulation and tertiary frequency modulation, and the primary frequency modulation plays an important role in maintaining the frequency stability of the power network. Meanwhile, as new energy power generation with the characteristics of intermittence, uncertainty and volatility such as wind power generation and photovoltaic power generation is connected to a power grid in a large scale, severe power fluctuation or fault exit of the new energy power generation can generate non-negligible influence on the frequency stability of the power grid, the new energy power generation does not have the frequency modulation capability, and a conventional unit must bear the frequency modulation task caused by the power fluctuation or fault exit. At present, domestic frequency modulation power supplies are mainly thermal power generating units, however, due to the defects of low response speed and low climbing speed, the dynamic characteristics of the power supply are influenced by nonlinear factors such as frequency modulation dead zones, frequency modulation upper and lower limits, unit hysteresis rate and the like, the frequency modulation quality and flexibility are difficult to meet requirements, even a power back-modulation phenomenon occurs, and the situation is particularly obvious in isolated operation regional power grids. Although the frequency modulation performance of the hydroelectric generating set is superior to that of the thermal power generating set, the construction of the hydroelectric generating set is limited by geographical conditions, and the available frequency modulation capacity is limited.
