With the advent of smart electricity grids, a new organizational model has been established in the electricity sector, driven by the growing integration of distributed energy resources (DERs) into the grid. The integration of DERs offers flexibility in the operation of electricity networks, allowing prosumers to act in the business chain offering services such as energy balance, reactive support, restoration of supply, among others. In this context, this thesis proposes a computational simulation model for smart electricity grids (SiMSG) as well as an instance of this model applied in the construction of an architecture of transactive energy systems (TES), the SiMTES, which uses SiMSG for its implementation in a case study. SiMSG is based on three main concepts: the recasting methodology for composing computer simulation models, the integration of multidomain tools via co-simulation and the implementation of distributed behavior via multi-agent systems (MAS). The proposed simulation model enables the integration of the different domains of the smart electricity grids through the joint use of simulators that compose a multi-domain analysis platform, enabling the representation and simulation of control actions, optimization, network analysis, communication, etc., which are necessary for modern electrical power systems. The SiMTES architecture, proposed as an application of the SiMSG model, is used as a proof of concept for the simulation model, being modeled based on the MAS concept and having as its main operational characteristic the definition of two phases: operation programming phase and real-time operation phase. The developed model is applied in a medium/low voltage electrical energy distribution network with 74 nodes, and a Low Power Wide Area (LPWA) type communication system. The results obtained in the simulations show the coherence of the SiMSG/SiMTES architecture and the usability of the simulation model, with the activation of directly controllable network storage devices as a priority and the clear influence of the change in energy prices on the programming of storage energy devices of prosumers. Furthermore, the times established between the operational phases were validated both for the topology and for the parameters of the proposed LPWA communication network
