A control method for a new energy power system in the multi-source and multi-control domain operation mode

Abstract

The invention discloses a control method for a new energy power system in a multi-source and multi-control domain operation mode, which belongs to the field of active power dispatching control of electrical engineering. The invention adopts a multi-source multi-domain control method, introduces closed-loop feedback, and controls the generator set to track the load increment in real time to ensure that the frequency is at the required level. By tracking the adjustable load (the load component with a change period between 10 seconds and a few minutes), defining the correlation coefficient between the adjustable load and the generator set, and realizing the effective control of the load weight, it can balance the power consumption load and the power generation system. stabilizing ability to realize the safe and stable operation of the power grid.

Description

technical field [0001] The invention belongs to the field of active power dispatching control of electrical engineering, and in particular relates to a control method for a new energy power system in a multi-source and multi-regulation domain operation mode. Background technique [0002] With the continuous and rapid increase in the scale and speed of the connection of energy storage equipment such as electricity storage and heat storage in various energy forms to the new energy power system, the load change curve in the large power grid and the fluctuation of wind power, photovoltaic and other new energy power generation forms and their Uncertainty, the traditional single control method has been unable to fully adapt to the various complex operation modes of the power grid under different load levels and its changing characteristics. [0003] Closed-loop control is often used in grid power generation control, which aims to reduce the frequency rise and fall of the grid caus...

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
