Embodiment 1

[0066] The present invention provides a method for coordinating wind storage access to network sources, including:

[0067] Determining the benefits of combined wind-storage systems and grids;

[0068] Taking the wind-storage combined system and the power grid as game participants, the optimal coordination scheme for wind-storage access to the grid source is determined according to the pre-built wind-storage-grid coordination planning game model;

[0069] The wind storage-network coordination planning game model is constructed according to the income of the wind storage combined system and the power grid.

[0070] When implementing the present invention: as figure 1 As shown, the flow chart of the coordination method of wind storage access network source based on complete information dynamic game includes the following steps:

[0071] A. Based on the dynamic game theory of complete information, take the combined wind storage system and power grid as game participants, analyz...

Embodiment 2

[0181] Based on the same inventive concept, the present invention also provides a coordination system for wind storage access to network sources, including:

[0182] The collection module is used to collect relevant parameters of the combined wind-storage system and power grid, and generate a game tree;

[0183] The determination module is used to determine the optimal coordination scheme of the wind storage access network source according to the game tree and the pre-established wind storage-network coordination planning game model;

[0184] Wherein: the pre-established wind storage-grid coordination planning game model includes an investment benefit model with the wind storage combined system and the power grid as game participants, and the investment benefit model of the game participants is based on the operating parameters of the wind storage combined system and the power grid and economic parameters to construct.

[0185] Further, it also includes a building block for p...

Abstract

The invention relates to a coordination method and system for a wind storage access network source. The method comprises the steps that the benefits of a wind storage combined system and a power gridare determined; the wind storage combined system and the power grid are taken as game participants, and the optimal coordination scheme of the wind storage access network source is determined according to a pre-built wind storage-network coordination planning game model; and the wind storage-network coordination planning game model is built according to the benefits of the wind storage combined system and the power grid. According to the invention, in the market environment, the dynamic game planning of both sides of the wind storage-network is conductive to improving the enthusiasm of the power grid to absorb wind power, and is conductive to avoiding the blind configuration of energy storage; and an improved scheme is provided for source network uncoordination in the current planning of awind storage combined power plant.

Description

technical field [0001] The invention relates to a coordination method in the fields of new energy power generation, energy storage and power system planning, and in particular to a coordination method and system for wind storage access to network sources. Background technique [0002] In recent years, energy storage system grid connection and grid expansion planning are considered to be one of the powerful measures to solve the current problem of wind power consumption. However, due to the independent planning of wind power, energy storage, and power grid stakeholders, while investment is wasted, the problem of wind curtailment has not been well resolved. Therefore, in the current market environment, how to realize wind-storage-grid coordinated planning has become a key issue worth studying. [0003] With the large-scale development of wind power, the impact of its volatility and intermittency on the system is becoming more and more prominent, which has become a serious obs...
