Problems solved by technology

[0008] The existing three pricing methods Because the current initial investment price of energy storage projects is too high, the discharge electricity price of energy storage determined according to the cost pricing method is much higher than the power generation price of coal-fired units, and a certain subsidy mechanism needs to be established

Embodiment 1

[0098] The present invention is a two-tier pricing method for energy storage aggregation platforms, such as figure 1 as shown, figure 1 It is an overall flow chart of the two-tier pricing method of the energy storage aggregation platform of the present invention.

[0099] Specifically, the present invention is a two-tier pricing method for the energy storage aggregation platform, which refers to the pricing method between the aggregation platform and the power grid for the distributed energy storage and aggregation platform. In the first layer, the aggregation platform centralizes and distributes distributed energy storage and prices it through long-term contracts. In the second layer, the power grid sets prices for different aggregators through real-time electricity prices.

[0100] The present invention is a two-tier pricing method aimed at the energy storage aggregation platform, which is aimed at the pricing method between the distributed energy storage and the operation ...

Embodiment 2

[0156] The present invention is a two-tier pricing method for energy storage aggregation platforms, such as figure 1 as shown, figure 1 It is an overall flow chart of the flexible self-starting method of the wind storage isolated grid system of the present invention. It is consistent with the steps in Example 1, it is worth noting that from figure 1 It can be seen from the process in the figure that the energy storage aggregation platform participates in the auxiliary services of the power grid through bidding and bidding. Since the power grid company occupies a dominant position, there is a master-slave game in the bidding process. Distributed energy storage devices are numerous and scattered, so different aggregators have different distributed energy storage devices.

[0157] The power grid company will anticipate the impact of the output it decides on the following aggregation platform. It is in consideration of this influence that the decision of the power grid company...

Abstract

The invention belongs to the technical field of power system economy, and particularly relates to a double-layer pricing method for an energy storage aggregation platform. The method aims at a distributed energy storage and aggregation platform and a pricing mode between the aggregation platform and a power grid; in the first layer, the aggregation platform concentrates and disperses distributed energy storage and prices through a long-term contract, and in the second layer, the power grid prices different aggregators through real-time electricity prices. According to the method, the power deviation prediction model of the wind storage isolated network system is established, power and voltage regulation is implemented under the condition of considering the power deviation, and the reliability and practicability of self-starting of the wind storage isolated network system are greatly improved. According to the double-layer pricing method, pricing of the energy storage aggregation platform is effectively and reliably carried out, and a technical basis and a practical method are provided for double-layer pricing of the energy storage aggregation platform; and the distributed energy storage pricing efficiency is effectively improved, complex pricing of a large number of energy storage devices by a power grid is simplified, implementation is easy, commercialized development is facilitated, and the method has good commercial development prospects.

Description

technical field [0001] The invention belongs to the field of power system economy and technology, and in particular relates to a two-tier pricing method for an energy storage aggregation platform, specifically a pricing method for distinguishing between a distributed energy storage device and an aggregation platform, and between an aggregation platform and a power grid. Background technique [0002] Energy storage is an important link in modern energy systems and one of the key supporting technologies for smart grids. The large-scale development of renewable energy power generation and a high proportion of grid connection put forward higher requirements for the flexible adjustment capability of the power system, thus giving birth to the development of the energy storage industry. Energy storage systems can be widely used in the generation, transmission, distribution, and utilization of power systems, which can improve the safety, reliability, and flexibility of power grids. ...
