Abstract

The embodiment of the invention discloses an energy scheduling method, a distributed energy system, and a distributed energy network system. The method includes that a first distributed energy system,when requiring energy scheduling, issues bidding information and receives the bidding information from a bidding distributed energy system, and determines, according to total scheduling amount, the demand-side response and the scheduling section of the bidding distributed energy system, and the unit energy cost of each scheduling amount in the scheduling section, respective distributed energy systems wining the bidding and respective scheduling amount. It can be seen that the first distributed energy system can determine, according to its own total scheduling amount, the demand-side responseand the scheduling section of the bidding distributed energy system, and the unit energy cost of each scheduling amount in the scheduling section, the respective distributed energy systems wining thebidding and respective scheduling amount. Therefore, the comprehensive energy utilization efficiency and supply-demand matching in the entire distributed energy network system can be improved.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to an energy scheduling method, a distributed energy system, and a distributed energy network system. Background technique [0002] Renewable energy such as wind power and photovoltaics has attracted widespread attention from all over the world due to its environmental friendliness and renewable characteristics. However, the uncertainty of its primary energy has a certain impact on the operation and power quality of the power system. To alleviate power fluctuations, power grid dispatching usually limits its output scale, thus causing serious wind and solar curtailment. [0003] Distributed energy system (DES) is one of the development directions to solve the problem of renewable energy consumption. Compared with the traditional centralized energy supply system, DES is composed of small distributed power sources (such as gas internal combustion engines, gas turbines, etc.) ), loads ...
