Abstract

The invention provides a generating cost grade-based power distribution control system and a method. The system comprises a coordinating controller, distributed energy sources and a distributed controller, wherein the coordinating controller calculates a unit time generating cost of each distributed energy source, and then the generating cost grade of each distributed energy source is determined according to the calculation result; the coordinating controller controls the distributed energy sources in areas to work according to a calculated output power of each area, and then achieves that: for every area, one of the distributed energy sources with the lowest generating cost grade works at an output power higher than a first preset value, and the remaining distributed energy sources with the lowest generating cost grade work at an output power higher than the first preset value; when the output power of any one of the distributed energy sources reaches a rated value, the distributed energy sources of which the output power is higher than the first preset value but not higher than a second preset value are increased in priority; moreover, the lower the generating cost grade is, the distributed energy sources are controlled to be increased in a higher priority.

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...
