  7. Abstract:
  8. Nowadays, with the expansion of restructuring and privatization in power systems, energy markets are growing rapidly, within distribution networks. In order for such markets to be implemented in practice, the technical constraints and issues of the distribution network, which are mainly the power loss and congestion of lines and also the bus voltage violations, must also be considered within the framework provided for them. Hence, this dissertation presents some new structures for Peer-to-peer (P2P) energy markets, in which the technical issues of the distribution network could be considered. Moreover, a model predictive control method is used in the proposed structures of this dissertation in order to enhance the precision of the agents’ optimal decisions in the P2P market. These structures are designed within a multi-agent system concept, which assumes the distribution power grid or microgrid to be consist of several independent agents.In this regard, in this dissertation, in the first step, a decentralized peer-to-peer active power market framework in a microgrid is presented without considering the technical issues of the network. In the second step, considering the congestion and loss of lines, a decentralized peer-to-peer market framework is designed for active power; and in the last step, considering the voltage violation of the network’s buses, a decentralized peer-to-peer market framework is designed for reactive power, in the distribution network. In order to test the performance of the proposed frameworks, the designed active power market structure for microgrids is tested within a 10-bus microgrid system, and the designed active and reactive power market structures for distribution systems, are tested within the modified 37-bus IEEE test system
