摘要：

In order to control the distributed renewable energy (DRE) and controllable load flexibly to participate in market transactions and optimal dispatch, an optimal dispatching model for AC/DC hybrid microgrid (AC/DCHM) with virtual power plants (VPP) based on bi-level multi-objective robustness is proposed. The VPP technology is used to suppress the uncer-tainty of power generation and consumption, and the robust theory is used to construct the uncertain aggregate which can adjust the boundary flexibly. According to the characteris-tics of the model, multi-objective moth-flame optimization (MOMFO) is used. The results show that the model can make up for the lack of traditional robust optimization that is too conservative, and deal with the defects of microgrid load, poor source predictability, and insufficient dispatchable resources and means. It will balance the income entities of each level, the profit of microgrid can be increased by 7.3% with VPP. On the premise of ensur-ing the stable operation, the confidence probability of the uncertain variables of load and source can be reasonably selected, and the profit can be increased by 22.8%. Therefore, the sustainable development of electric power economy can be effectively realized. © 2020, High Voltage Engineering Editorial Department of CEPRI. All right reserved.
