Abstract

The present invention provides a power distribution control system and method based on power generation cost levels. The system includes a coordination controller, a distributed energy source, and a distributed controller. The coordination controller performs the power generation cost per unit time of each distributed energy source Calculate, and then determine the power generation cost level of each distributed energy source according to the calculated result; the coordination controller controls the work of the distributed energy sources in the area according to the calculated target output power of each area, and then makes: for each area, the power generation One of the distributed energy resources with the lowest cost level works with an output power higher than the first preset value, and the remaining distributed energy resources with the lowest power generation cost level work with an output power higher than the first preset value; When the output power of any one of the distributed energy sources reaches the rated value, the distributed energy sources whose output power is higher than the first preset value and not higher than the second preset value are given priority to increase; moreover, the lower the power generation cost level, the lower the Increased by priority control.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to a power distribution control method based on power generation cost levels. Background technique [0002] The power distribution system consists of a distribution substation (usually reducing the transmission voltage of the grid to a distribution voltage), a high-voltage distribution line (that is, a voltage above 1 kV), a distribution transformer, and a low-voltage distribution line (below 1 kV Voltage) and corresponding control and protection equipment. The distribution voltage is usually 35-60 kV and 3-10 kV. It is actually a link that is directly connected to the user and distributes electric energy to the user. At the same time, distributed energy is also widely used in the field of power supply. [0003] Active power distribution technology refers to the introduction of an active control mechanism in the distribution network to achieve the optimal configuration of the di...
