Active power distribution network economic operation method for distributed energy interaction consumption

Abstract

The invention discloses an active power distribution network economic operation method for distributed energy interaction consumption. The method comprises when the total power generation amount and the total electricity consumption amount are not balanced, and the actual value of the electricity consumption of the current time period of a distributed energy resource deviates from the day-ahead planning amount, calculating the cost of the distributed energy resource for asking other distributed energy sources in the active power distribution network to consume the power deviation value deviating from the day-ahead planning amount; receiving the consumption response price fed back by the distributed energy resource for consuming the power deviation value, and generating an interactive operation scheme by adopting the consumption response price less than the cost; calculating the actual economic benefit generated by the interactive operation scheme by means of a constructed active powerdistribution network interactive operation economy model; performing safety verification on the interactive operation scheme with the optimal actual economic benefit by adopting the operation parameters of the active power distribution network; and when the interactive operation scheme of the optimal actual economic benefit meets the safety verification, controlling the active power distribution network to operate by adopting the interactive operation scheme.

Description

technical field [0001] The invention relates to the fields of energy distribution, electric power dispatching and electric power market, in particular to an economical operation method of an active distribution network for distributed energy interactive consumption. Background technique [0002] Active distribution network refers to a distribution network that contains distributed energy and has self-control, management and operation capabilities. A large number of distributed energy equipment is connected to the power grid, which is easy to cause problems of overvoltage, blocking, and relay protection, and the output of distributed energy generation is highly volatile, which often restricts distributed energy from connecting to the grid, resulting in a large amount of abandoned power generation. Promoting the interactive consumption of distributed energy in the active distribution network will avoid the waste of distributed energy, improve the capacity of the active distrib...

AI Technical Summary

Problems solved by technology

[0003] Existing active distribution network operation methods, such as "residual electricity connected to the grid", "forced quota system", "power generation subsidies" and "priority connected to the grid", have promoted the consumption of distributed energy to a certain extent, but they all sacrificed the benefits of some market players. Economic interests can only improve the competitiveness and market participation of distributed energy in the short term
