Embodiment Construction

[0019] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. However, it should be understood that many implementation-specific decisions must be made in developing any such practical implementation in order to achieve the developer's specific goals, and that these decisions may vary from implementation to implementation . Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0020] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure closely related to the solution according to the present invention is shown in the drawings, and the relationshi...

Abstract

The invention discloses a method and equipment for controlling an energy storage device. The maximum power of the energy storage device is set as PMAX. The method comprises the following steps of: receiving an automatic generation control (AGC) instruction from an electricity grid, wherein the AGC instruction comprises a target power PAGC of output electric energy; detecting an actual power PGEN, generated by a generator according to the AGC instruction, of the output electric energy; when the target power PAGC is greater than the actual power PGEN, controlling the energy storage device to supply the electric energy within an interval between 0 and PMAX; or when the target power PAGC is smaller than the actual power PGEN, controlling the energy storage device to absorb the electric energy within the interval between 0 and PMAX. Generation equipment which is provided with the energy storage device can respond to the AGC instruction of the electricity grid more quickly and more accurately, and the generation equipment has higher ability to help an electric power system to solve the problems of power balance and frequency fluctuation, so the stability and reliability of the whole electric power system are improved.

Description

technical field [0001] The invention relates to the field of electric power, in particular, to a control method and equipment for an energy storage device. Background technique [0002] The power system includes the power grid, generators that provide electrical energy, and various electrical equipment. It is hoped that the electric energy provided by the generator and the electric energy consumed by the electrical equipment are balanced in real time, so as to achieve stable and reliable operation of the entire power system. However, those skilled in the art know that due to the fluctuation and randomness of electric energy consumed by electrical equipment, for example, a certain electrical equipment is suddenly switched on or off, or due to random accidents of generators and power grids, etc. Possibility to achieve complete power balance. However, it is always desired that the electric energy provided by the generator be balanced with the electric energy consumed by the e...
