Optimal energy scheduling of a stand-alone multi-sourced microgrid considering environmental aspects

A standalone microgrid with renewable and regular power resources along with storage system play an important role in remote areas in order to solve power supply problems. In this research, an optimal energy management of a standalone microgrid under different operational modes is studied. The objective of the optimization model is to improve energy utilization efficiency; reduce fuel cost and gas emissions by scheduling productions of energy resources in each hour on the next day. In another word, the problem is modeled as a constrained single-objective programming to minimize cost of power and emission generations. The system is tested under two different operational policies where microgrid power generation sources work with and without battery storage system. Then the final results are compared and investigated. The results show a considerable reduction in system total cost and generated emission in comparison with previously proposed methods.
