Problems solved by technology
[0007] The disadvantages of the grid energy storage participating in frequency regulation schemes in the above prior art are: these schemes can only optimize the operation of the energy storage power station and analyze the economics, but for the auxiliary services of the regional power grid energy storage power station participating in auxiliary frequency regulation, Economic optimization is only the basis for the long-term operation of energy storage power stations, and there is a lack of economic compensation and reasonable pricing mechanisms suitable for regional grid hybrid energy storage to participate in frequency regulation

The invention provides a regional power grid hybrid energy storage auxiliary frequency modulation economic optimization and compensation pricing method. The method comprises the steps that a regional power grid hybrid energy storage auxiliary service scene is considered, and a regional power grid energy storage auxiliary thermal power generating unit frequency modulation model is established based on a set objective function, constraint conditions and decision variables; performing primary frequency modulation cost minimum economical efficiency optimization calculation on the regional power grid energy storage auxiliary thermal power generating unit frequency modulation model according to a set time interval to obtain a pricing mechanism of each type of energy storage power station; and independently carrying out settlement on each type of energy storage power station by utilizing a pricing mechanism, and determining a compensation cost pricing standard of each type of energy storage power station. According to the invention, the power distribution of the energy storage units in each energy storage power station in the hybrid energy storage system in the regional power grid is considered through the economical efficiency optimization method, so that the condition of mutual charging and discharging between each energy storage unit of each energy storage power station of the hybrid energy storage system is avoided; and determining a pricing mechanism according to the difference between the economic compensation income and the frequency modulation cost and considering a reasonable profit space.
Description
technical field [0001] The invention relates to the technical field of power grid energy storage management, in particular to a regional power grid hybrid energy storage auxiliary frequency regulation economic optimization and compensation pricing method. Background technique [0002] With the continuous increase in the proportion of new energy units in the power grid, the intermittent and fluctuating power supply of the power grid has become more and more significant, resulting in a decline in power quality and aggravation of frequency fluctuations, which seriously affect the safe and stable operation of the power grid. The defects of the traditional frequency modulation method of thermal power units are becoming more and more prominent: slow response, low precision and low ramping efficiency make thermal power units unable to track the AGC (Automatic Generation Control, automatic generation control command) of the current power grid very well. [0003] As one of the soluti...
