Problems solved by technology

However, the development of my country's energy storage industry is in the initial stage of exploration. The initial investment is large, and it is difficult to recover the cost and obtain considerable profits in the short term. There are relatively few domestic support and incentive policies and methods. Among the existing subsidy policies There is a lot of ambiguity and variability, resulting in a low enthusiasm for energy storage to participate in the provision of auxiliary services

Embodiment

[0070] Taking a 10kV distribution network in a certain area of ​​Shanghai as an example, the average annual growth rate of load in this area is 1.5%. The power grid area contains 15MW wind turbines, and the power supply company dispatches energy storage systems to meet the backup needs of the distribution network, so as to achieve the purpose of peak shaving and valley filling, improving the grid connection rate of new energy sources and power supply reliability. :

[0071] The benefits obtained by the distribution network and the operation of energy storage investment are shown in Table 1;

Abstract

The invention relates to a method for determining an economic subsidy standard for backup power generation provided by an energy storage system, comprising the following steps: calculating the annual benefit obtained when a power supply company dispatches energy storage to provide backup in a distribution network; Cost; calculate the annual expenditure and annual income of the energy storage system; determine the economic subsidy standard given by the government to the energy storage system. This method aims to design the economic subsidy mechanism given by the government to the energy storage system to ensure that the energy storage system can operate profitably under the current development level of energy storage technology, improve the market competitiveness of the energy storage system, and thus encourage independent investors to invest Energy storage construction.

Description

technical field [0001] The invention relates to a calculation method, in particular to a method for determining an economic subsidy standard for standby power generation provided by an energy storage system, and belongs to the technical field of in-store system assistance. Background technique [0002] With the gradual increase of renewable energy grid-connected scale and the continuous change of load demand characteristics, the peak-to-valley difference and backup demand in power grid operation are increasing. The quality of auxiliary services puts forward higher requirements. It is difficult to stabilize the fluctuation of system load after the intermittent new energy is connected to the grid only by relying on conventional peak-shaving and standby units. The problem of grid peak-shaving and reserve capacity is becoming more and more serious. In particular, it has brought great challenges to the security and stability of power grids that have lost the peak regulation of sm...
