Energy management of a multi-microgrid system

Existing optimization models (Ren et al. (2014); Kargarian et al. (2012); Nguyen and Le (2013)) only minimize the operational cost of a multi-micorgrid system and do not consider the pollutants (CO2, NOx, SOx, etc.) emitted by the controllable generating units within the microgrids and thermal power plants of the main grid (Lora and Salomon (2005)). These pollutants have a negative impact on the environment as they cause droughts, acid rain, heat waves, hurricanes, increase in sea levels, increase in average global temperature, increase in infectious and allergic diseases, etc. (Franchini and Mannucci (2015)). The aim of this study is to address this problem by formulating a constrained multi-objective optimization model which simultaneously minimizes the operational cost and environmental impact of a multi-microgrid system.
