   Cooperative Operation of Renewable-Integrated Multi-Energy Microgrids Under Dynamic Rolling Horizon Strategy
By Zhengmao LI, Jorma KYYRÃ„, Xu YAN, Tianyang ZHAO, Yunqi WANG [View]
[Download]

Abstract: In this paper, a cooperative operation method is proposed in a multi-energy microgrid with high penetration levels of renewable energy sources. To handle uncertainties rising from wind turbines and photovoltaic cells, the rolling optimization approach is thus applied to achieve online multi-energy management with the constantly updated information. Through the effective coordination of energy markets, multi-energy networks, energy storage systems, and generators, a reliable and economic operation scheme is fulfilled. At last, to show the effectiveness of our proposed method, a case study with two compassion cases for the operation of multi-energy microgrids is done. The simulation results indicate that our method is more cost-effective for the cooperative operation of renewable-integrated multi-energy microgrids under uncertainty sources.

   Hierarchical Power Flow Voltage Assessment of a Multi-Microgrid in Interconnected Operation Mode
By Gibran David AGUNDIS TINAJERO, Juan C. VASQUEZ, Josep M. GUERRERO [View]
[Download]

Abstract: This paper presents a voltage assessment of the IEEE six-bus system including two controlled microgrids using the hierarchical power flow approach. Two case studies are presented, the first case considers only primary droop controls for the distributed generation units, and the second caseconsiders primary droop and secondary controls. The results shown that there is a difference in theanalysis results if only primary controls are considered or hierarchical controls. In this way, itis shown that the microgrid connection impacts in the overall system voltage profile and indicatethat planning analysis, considering the detailed modelling of the different distributed generationunits' hierarchical controls, is required for the optimal inclusion of microgrids into the main grid.
