An Innovative Sustainable Multi-Energy Management Framework for Full Renewable Grid-Tied Microgrids Under the Transactive Energy Paradigm

Abstract

The significant growth in thermal and electrical energy demand along with the simultaneous emergence of hybrid energy systems have made the uninterrupted clean multi-energy supply with adequate sustainability and flexibility a critical challenge under the current independent energy structures. This paper develops an innovative sustainable multi-energy management framework by adopting transactive energy capabilities in the energy sharing of multi-carrier multi-microgrids. The developed model allows microgrids to benefit from the optimal integration of 100 % renewable energy sources for fully producing carbon-free energy. The proposed framework enables microgrids to fairly trade energy with each other in the local multi-energy sharing environment for effectively realizing environmental and economic objectives. Herein, the stochastic volatilities of the solar irradiation, multi-energy prices, and wind speed are simultaneously modeled by developing the distributionally robust chance-constrained methodology to ensure the achievement of a sufficient level of robustness as well as a satisfactory economic advantage. The results highlighted achieving 11.36 % cost savings for microgrids when they are operated under the proposed model. Indeed, the outputs indicated the applicability of the suggested model in reducing microgrids’ dependency on the grid, supplying continuous multi-energy, and improving the system's robustness and economic benefits.
