Embodiment Construction

[0101] In order to clearly illustrate the technical characteristics of this solution, the following will describe this solution through specific implementation modes and in conjunction with the accompanying drawings.

[0102] The energy storage system in this patent is to compensate the prediction error of wind power, so that the output of the wind power plant can track the planned output. According to the planned output curve, the charging and discharging process of the energy storage is controlled, so that the actual output power of the wind power plant is as close as possible to the planned output. Here, the predicted output of wind power is used as the planned output.

[0103] The power configuration of the energy storage system is based on the wind power forecast error. The energy storage system compensates the difference between the actual wind power and the planned output in real time (that is, the forecast error e), so that the wind power plant can be converted from a...

Abstract

The invention discloses an energy storage system optimization method with wind power prediction errors compensated, which comprises the following steps: (1) the wind power prediction errors of a windpower plant are analyzed to obtain a prediction error distribution law; (2) a mathematical model of rated power and rated capacity of the energy storage system is built; (3) under a certain error compensation degree, an objective function with the purpose of maximizing the income of the wind power plant is built; and (4) the influence of the change of the electricity price and the energy storage cost on the income of the wind power plant is considered from the perspective, and an electricity price interval and an energy storage cost interval which enable energy storage to have investment valueare found out.

Description

technical field [0001] The invention relates to the technical field of wind power plant energy storage, in particular to an optimization method of an energy storage system for compensating wind power prediction errors. Background technique [0002] As a high-quality renewable energy, wind power has developed rapidly in recent years. However, as the penetration rate of wind power continues to increase, while wind power supplies a large amount of clean power to the grid, its power output is uncertain, random, and fluctuating. It also poses a huge challenge to the safe and reliable operation of the power grid. [0003] The energy storage system can provide fast response capacity for the power system. It has the characteristics of dynamically absorbing energy and releasing it in a timely manner. It can realize the time migration of power and energy and help to achieve the power and energy balance of the power system under various working conditions. Configuring a suitable energ...
