  7. Abstract:
  8. Distribution power systems are undergoing a fundamental transition with the introduction of microgrids (MGs) and proliferation of renewable energy sources inspired mainly by privacy and environmental concerns. In this regard, energy management methods employed by utilities should take into account the intermittent nature of RESs power production while coping with the independent operation of MGs. Transactive energy (TE) is an emerging concept which utilizes economic-based mechanisms to facilitate the dynamic and decentralized management of active agents of the system. However, the energy transactions between transactive agents could have adverse impacts on the technical aspect of the system if not properly managed and coordinated. In this thesis, a transactive energy management framework for distribution systems with multi-MGs structures is proposed to deal with the economic issues in energy trading and the technical issues in distribution system operation in a holistic manner. Moreover, the alternating direction method of multipliers (ADMM) is utilized for distributed implementation of the proposed scheme. As a result, the proposed energy management framework does not rely on a central coordinator and communication is only required between adjacent agents. This could dramatically reduce communication complexity and enhance system’s security. In addition, distribution locational marginal price (DLMP) is suggested as a transactive control signal to coordinate the operation of microgrids. In this respect, a new approach that enables agents to distributedly estimate DLMP in the context of ADMM procedure is developed. Furthermore, the proposed scheme provides the possibility that different control mechanisms be employed to schedule local resources in each microgrid. Here, the robust optimization technique is deployed in the MG operational scheduling to handle the uncertainty and variability associated with renewable energy resources. Finally, numerical tests on IEEE 37-bus distribution system demonstrate the effectiveness of the proposed framework and the efficiency of the distributed algorithm
