Abstract

The invention provides a consumption optimization method and device for an energy unit, and the method comprises the steps: simulating the obtained output historical data of the to-be-consumed and optimized energy unit through a Monte Carlo method, generating the output scenes of the energy unit, and carrying out the clustering of the output scenes of the energy unit through a clustering algorithm, obtaining each typical output scene of the energy unit; according to each typical output scene of the energy unit, the operation information of each pumped storage power station corresponding to the energy unit and the operation information of the power grid where the energy unit is located, constructing a pumped storage optimization model of the energy unit; and solving the pumped storage optimization model through the simulation platform to obtain an operation state result of each pumped storage power station and a consumption result of the energy unit. By applying the method, the optimization efficiency can be effectively improved, the wind curtailment rate and the light curtailment rate are reduced, and the maximum consumption of energy in each typical scene is realized.

Description

technical field [0001] The present invention relates to the technical field of power systems, in particular to a method and device for optimizing the consumption of energy units. Background technique [0002] Modern life has become more and more inseparable from electricity. Common technologies mainly generate electricity through thermal power, water power, wind power, etc. to obtain electricity. With the improvement of environmental protection awareness, people are more and more inclined to use renewable clean energy for power generation. In order to reduce greenhouse gas emissions, protect the ecological environment, and achieve the goal of "carbon peaking and carbon neutrality", wind power will be used in the future. The proportion of renewable energy power generation represented by photovoltaic power generation in the power system will be higher and higher. [0003] However, renewable energy power generation is uncertain and easily affected by factors such as the enviro...
