Embodiment Construction

[0031] The present invention will be described in more detail and complete below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

[0032] New energy power generation technology refers to the technology that uses wind energy, light energy (solar energy), geothermal energy, etc. to generate electricity. New energy sources such as wind power and photovoltaics have inherent characteristics such as volatility, randomness, and uncontrollability. The instability of new energy power generation will further cause the instability and uncertainty of new energy power generation. Therefore, for the new energy power generation system that needs to be...

Abstract

The invention relates to the technical field of energy storage, in particular to a new energy power generation system and a method capable of making up power prediction accuracy. The system comprises a numerical weather forecast server, a computing system and a monitoring system, wherein the numerical weather forecast server is connected with the computing system and used for transmitting weather forecast data to the computing system; a power prediction server in the computing system predicts power according to related data information; the computing system is connected with the monitoring system and transmits the predicted power to the monitoring system; and an energy storage management unit in the monitoring system controls an energy storage unit to charge or discharge according to the predicted power to realize peak clipping and valley filling. The system realizes the peak clipping and the valley filling for ultrashort-term prediction precision and short-term prediction precision and makes up a prediction accuracy error through interaction between hardware. Therefore, stable power output of the new energy power generation system is realized after grid-connected operation.

Description

technical field [0001] The invention relates to the field of energy storage technology, in particular to a new energy power generation system that compensates for the accuracy of power prediction. Background technique [0002] New energy power generation technology refers to the technology that uses wind energy, solar energy, geothermal energy, etc. to generate electricity. New energy sources such as wind power and photovoltaics have inherent characteristics such as volatility, randomness, and uncontrollability. After the grid-connected application of the power generation system using new energy, if the power of the new energy power generation system cannot be effectively predicted and determined, it will cause hidden dangers to the safety and stability of the interconnected operation of the large power grid, and bring certain problems to the frequency regulation and reserve capacity planning of the power grid. The impact of power flow will have an impact on electrical chara...
