Abstract:
The paradigm of smart energy community refers to a set of households that share a Microgrid and have local renewable production and distributed energy storage. In this context, the main issue is the low dispatchability of the renewable generation, which requires large storage capacities to maximize the degree of self-consumption. A more favorable scenario is found when considering a grid connected system, which reduces the dependence on the stochastic nature of renewable resources, allowing the consumers to import energy from the grid when neither local production nor storage is available. Moreover, the surplus generation could also be injected into the electrical network, having in some cases feed-in tariffs. Thus, this paper aims to present a simulation scenario where the interaction between a Smart Community with high penetration of Photovoltaic generation and the main grid is studied, and how this integration can drive to a net-zero energy system. Results for self-consumption and self-generation indexes are presented for different Photovoltaic power rates and storage capacities, showing that net-zero smart energy communities are a plausible scenario when bidirectional energy flows with the grid are considered.
