Providing a comprehensive energy management strategy for operation of multi-microgrids considering uncertainty of the fault occurrence

Today, the increased use of distributed generation units along with the storage devices as well as telecommunication enhancements have led to the formation of microgrids and thus multi-microgrids (MMGs). In this type of networks, the probability of the fault occurrence in different places of the network is not out of expectation, and it can be argued that the failure of the network not only increases the losses, reduces the efficiency and increases the outage, but also, it disrupts network operation and makes the operation process of the system more complex. From this point of view and with the aim of filling the existing research gaps, in this paper a comprehensive energy management strategy for operation of multi-microgrids considering uncertainty of the fault occurrence in the different part of the system is presented. In the proposed comprehensive energy management strategy, a novel problem formulation for both self-healing and cost effective operation, as well as the network operators’ relationship are considered. In this situation, at first, an appropriate method is proposed to address the contingency faults which can be occurred in the different places of the network, then intended energy management strategy is implemented. The proposed methodology is implemented in the MATLAB software environment and its effectiveness is demonstrated in the modified reliability based test system with considering some other traditional methods.
