| Sumario: | This work seeks to study stability from a technical-economic approach, in the context of future grids in which there will be a high penetration of renewable energies and flexible demand. A new way of operating and modeling electric power systems is studied, where the dynamics of the electric power system and the market, are coupled. The thesis postulates as a hypothesis that the coupling of the physical system dynamics with those of the electricity market, under a demand response scheme, in a smart grid with high penetration of renewable generation, could destabilize the system when the feedback signals, such as the price signal, are not correctly controlled. The results of the work indicate that it is possible to use a dynamic market mechanism to decrease the imbalance in real-time, and it is observed that market parameters, such as the speed of market-clearing or the elasticity of demands, can cause a stable base system to become unstable. As future work, it is proposed to adapt the models to better represent the reality of electricity systems, for example, by modeling the discontinuity of price signals or considering a multi-nodal market. |
