Converter coordination control method and converter coordination control device

Abstract

The invention discloses a converter coordination control method and a converter coordination control device. The method comprises the following steps: acquiring electric quantity data and signal data;calculating an acquired result, and issuing a corresponding control instruction according to a control target to be realized in different application scenes; and transmitting a control instruction toeach converter according to the control target. The device comprises a data acquisition device, a control device, a rapid communication device and a controlled power generation device; the data acquisition device is used for acquiring electric quantity data and signal data; the control device is used for calculating an acquired result and issuing a corresponding control instruction according to acontrol target to be realized in different application scenes; and the rapid communication device is used for transmitting a control instruction to the controlled power generation device according toa control target. According to the method, the problem of control consistency of converters with different characteristics and different parameters can be solved, and rapid control and output distribution of converter clusters are realized.

Description

technical field [0001] The invention relates to the field of new energy power generation control, in particular to a converter coordinated control method and a converter coordinated control device. Background technique [0002] With the increase in the proportion of new energy access, significant changes in the grid form and operating characteristics, due to the randomness, intermittent nature of new energy output, and poor controllability of units, large-scale new energy grid integration has brought new challenges to the operation of the grid. Stability, transmission, peak regulation, frequency regulation, reactive power / voltage and other issues threaten the safe and stable operation of the power grid. This puts forward higher requirements for new energy grid-connected technology and grid strength. [0003] At present, the research on the participation of new energy in grid security and stability control mainly focuses on the performance optimization of single-unit grid co...

Problems solved by technology

This kind of technology has a large communication delay and slow adjustment speed, which cannot give full play to the rapid response ability of new energy.

Especially in distributed power grids such as island power grids, when multiple machines need to cooperate to support the power grid, they can only rely on the droop control of the single machine itself for differential adjustment
