  7. Abstract:
  8. The purpose of this thesis is the presentation of an outage management scheme in a multi-microgrids system with a decentralized structure. The proposed method is designed in a two-step method to prevent damage to all microgrids and network components due to blackouts. In the first stage of this scheme, each microgrid alone provides its required power or curtails load due to the power deficiency. In the second stage, microgrids exchange power in a transactive energy environment, which is one of the new changes in active distribution systems with participation in market and price bidding, and all players of this market earn profit from their exchanges. In this case, the curtailed load will be provided as much as possible and to the maximum extent of the excess power of the microgrids. Based on the interpreted scheme, during the occurrence of unpredictable disasters that causes load curtailment in one constituent of the grid, a part of other constituent's power generation control is admitted to DSO. In this way, the DSO will be able to perform outage management to the desired network standards. On the other hand, comparison with previous studies that reviewed outage management of centralized systems, the implementation of decentralized optimal power flow in the second stage of this scheme with the ADMM algorithm, provides efficient privacy for all network agents. This algorithm only exchanges limited information with neighboring microgrids without the need for a central controller. In addition to the described scheme, in this thesis, voluntarily, the possibility of microgrids participating in the outage management scheme is also examined. In this vein, previously microgrid with the specification of a participation factor determines its cooperation in other outage condition and then a contract is adjusted between microgrid and DSO. According to the rules of this scheme, at the time of outage of microgrid components, it will receive the same amount of power from the other microgrids, and also it can sell more energy than its contract and receive a reward for the surplus sold in case of having economic efficiency and surplus power. The used network in this simulation is IEEE-34 nodes test system. Modellings are accomplished with Quadratic Programing (QP) method and optimization toolbax of MATLAB software
