چکیده

Optimal energy management in microgrids will increase their economic and technical efficiency, and it is usually carried out as an optimization problem for day-ahead operation strategies. Although many perspectives have been proposed for optimal operation, with increasing energy demand and imbalance between production and consumption, the lack of coherent planning to reduce costs and environmental consequences is still felt. Therefore, creating a new framework to consider uncertainties and operation issues simultaneously is necessary to increase reliability. For this purpose, in this paper, a two-level energy management system is presented at the first level determines the role of the load response program, the unit Synchronization, the generator unit production rate, and the storage charge and discharge rate, then the network reconfiguration in the presence of renewable energy sources is considered with the aim of maximizing the network operating profit and minimizing environmental pollutants at the second level. Also, the output power of renewable energy sources, including solar and wind, with uncertainty and scenario generation, has been considered. The presented model has been tested as a combination of two software, MATLAB and DigiSilent, on a 33-bus IEEE network to make it more realistic and increase the accuracy of the simulation. The results show that the load response program, along with the network feeder rearrangement and the problem of bringing the units into orbit simultaneously, in addition to reducing losses by 20% and increasing reliability by 10%, results in profitability for the microgrid operator.
