Control method of a new energy power system in a multi-source multi-regulation-domain operation mode

Abstract

The invention discloses a control method of a new energy power system in a multi-source multi-regulation-domain operation mode, which belongs to the field of active scheduling control of electrical engineering. The multi-source multi-domain control method is adopted, and closed-loop feedback is introduced, the generator set is controlled to track the load increment in real time so as to ensure that the frequency is at a required level. The load component with the adjustable load (changing period between 10 seconds to several minutes) can be tracked, and the correlation coefficient of the adjustable load and the generator set can be defined, so that the load weight can be effectively controlled. The electric load and the stabilizing capacity of the power generation system can be balanced, and safe and stable operation of the power grid can be realized.

Description

technical field [0001] The invention belongs to the field of active power scheduling control in electrical engineering, and specifically relates to a control method for a new energy power system in a multi-source multi-regulation domain operation mode. Background technique [0002] With the continuous and rapid increase in the scale and speed of energy storage equipment such as power storage and heat storage in various forms of energy being connected to new energy power systems, in view of the load change curve in the large power grid and the fluctuation of new energy generation forms such as wind power and photovoltaics, and its Uncertainty, the traditional single control method has been unable to fully adapt to the multiple complex operation modes of the power grid under different load levels and changing characteristics. [0003] Grid generation control mostly applies closed-loop control, which aims to reduce the frequency fluctuation of the grid caused by the difference ...

However, it does not take into account the control capability of the unit itself, and it is necessary to fully consider the role of abandoning wind, light, and nuclear power in regulating the output of the unit

[0007] There is no mention of the division and design of multi-source and multi-domain in the prior art. In order to respond to different control requirements and functions of different domains, improve the independence of different controller designs, and seek a balance between control accuracy and complexity, the present invention Propose a multi-source multi-domain control method
