Abstract

The invention discloses a micro-grid robustness multi-target operation optimization method containing renewable energy resources. The method comprises the steps of: collecting micro-grid operation information, generating an uncertainty implementation scene in micro-grid operation, constructing a robustness multi-target model according to micro-grid attributes, inputting the robustness multi-target model and the uncertainty implementation scene into a two-stage solving strategy, carrying out iterative solving respectively on an internal layer maximum optimization problem under the uncertainty scene and an external layer minimum optimization problem under an operation scheme until an ending condition is met and circulation is stopped, forming an optimal operation scheme set, and selecting an optimal operation strategy according to real-time prediction data. The optimal robustness non-domination leading edge of economy and environment can be obtained under a worst uncertainty condition. Compared with an existing operation optimization method, the operation optimization method provided by the invention realizes interference inhibition of uncertainty in the micro-grid operation under a multi-target framework.

Description

technical field [0001] The invention relates to a robust multi-objective operation optimization method for a microgrid containing renewable energy. Background technique [0002] In view of the efficient energy utilization and high economic and environmental benefits of microgrid, it has been widely recognized in the field of power and energy. And it is considered an important part of the Energy Internet, and even regarded as a powerful substitute for large power grids in remote areas and urban industrial parks. However, with the increase of renewable energy penetration rate and load uncertainty, the operation of microgrid seriously deviates from the optimal economic and environmental benefits, and the imbalance between supply and demand often occurs. Therefore, it is particularly critical to rationally dispatch distributed power output in the microgrid. [0003] In addition, the existing operation technology lacks the comprehensive consideration of the uncertainty and mult...
