Problems solved by technology

Electric power generation equipment must be able to be switched on and off quickly. For example, the response time of micro gas turbines is longer, and the input time of pumped storage power plants is shorter. However, fossil fuel power plants and nuclear power plants are not suitable for frequent start and stop.

Embodiment Construction

[0065] An energy storage power station includes an energy storage module and an energy storage control center.

[0066] The control center system of the energy storage power station includes an adjustable capacity prediction module, a module and a data management system. The specific description of each module is as follows:

[0067] The charge and discharge control module and the energy management adjustable capacity prediction module make predictions on the available capacity range of the energy storage unit in each period. Through the data management system, the statistical information of the energy storage system can be obtained in real time (including the total capacity up, the total capacity down, the number of energy storage units, etc.), the real-time information and historical data can predict the range of available capacity at any time, and upload it to the grid as a Reference basis for scheduling instructions. Of course, there may be a deviation between the expecte...

Abstract

Through calculating a capacity model of an energy storage power station and calculating adjusting power and a constraint condition of an electric quantity power model, a power adjusting capability and a power adjusting mode of the energy storage power station are determined and a control mode of a convertor is set. The energy storage power station absorbs power-grid electric power or supplied the electric power to the power grid. Power grid fluctuation is not caused. Voltage stabilization of the energy storage power station can be maintained. Peak-clipping flat valley of power of the power grid, rapid response of a frequency and fluctuation of the restrained power grid are realized. A power support is provided for emergency power supply of the power grid.

Description

technical field [0001] The invention relates to the technical field of power grid energy storage, in particular to an energy storage power station for power grid energy regulation. Background technique [0002] In order to improve the utilization efficiency of electric energy, the use of appropriate electric energy storage system can meet the demand during peak load without increasing the investment in grid capacity. A fundamental problem is that load conditions may vary daily, hourly, and seasonally, and equipment with sufficient capacity must be available to meet peak demand. In theory, electricity generation and electricity consumption should be equal. Electric power generation equipment must be able to be switched on and off quickly. For example, micro gas turbines have a longer response time, and pumped storage power plants have a shorter input time. However, fossil fuel power plants and nuclear power plants are not suitable for frequent start and stop. Furthermore, t...
