Abstract: La actualización de los sistemas de energía en los últimos años debido a la proliferación de la generación distribuida con fuentes de energía renovables, usuarios activos y vehículos eléctricos se ha convertido en un desafío. En este nuevo escenario, los prosumidores juegan un papel importante para amortiguar la curva de consumo y, por lo tanto, contribuir a los requisitos de la red. Los conjuntos fotovoltaicos (PV) integrados en edificios residenciales atraen una atención especial, ya que pueden complementarse con sistemas de almacenamiento de energía (ESS), como baterías o ultracondensadores (UC) o incluso una combinación de ambos, con el objetivo de lograr que los clientes puedan administrar su energía. Las razones anteriores justifican la necesidad de un sistema de gestión de energía (EMS) que coordine el funcionamiento de los dispositivos de almacenamiento de energía de manera optimizada, ya que son caros. En este documento, se propone un sistema de control integral para intercambiar energía entre los dispositivos de almacenamiento híbridos (baterías y UC) de dos viviendas con instalaciones fotovoltaicas con el fin de aumentar la disponibilidad de sus ESS y soportar los requisitos de energía durante el mayor tiempo posible, optimizando tamaños y costos, y evitando la saturación.The upgrade of power systems in the last years due to the proliferation of distributed generation with renewable energy sources, active users and electric vehicles has become a challenge. In this new scenario, prosumers play an important role in order to buffer the consumption curve and, therefore, contributing to the grid requirements. Special attention is attracted by photovoltaic (PV) arrays integrated in residential buildings, because they can be complemented with energy storage systems (ESSs), such as batteries or ultracapacitors (UCs) or even a combination of both, with the aim to achieve that customers could manage their energy. The above reasons justify the need of an energy management system (EMS) that coordinates the operation of the energy storage devices in an optimized way, as they are expensive. In this paper, a comprehensive control system is proposed to exchange energy between the hybrid storage devices (batteries and UCs) of two dwells with PV installations in order to increase the availability of their ESSs and support the energy requirements during the most time possible, optimizing sizes and costs and avoiding saturation.
