Analysis of the Self-Consumption Possibilities in Small Grid-Connected Photovoltaic Systems in Spain

This paper analyzes the self-consumption p ssibilities of the local electricity generated in a gridconnected to low voltage PV system. In particular, it focuses on theoretical and simulated studies of the energy flows and exchanges that take place within the system and the influence that Demand-Side Management and stor age systems have. Different factors based on the energy flows of the system have been defined for the stud y. Finally, an economic study, focused on the profitability shown by the self-consumption, has been included.
