Design and optimization of a grid connected residential PV-system with battery energy storage system

© 2018 IEEE. his paper studies a single-phase bidirectional grid tied inverter connected to a common DC-bus, together with a photovoltaic installation and a battery energy storage system. The design of this system and its control mechanisms are discussed. Appropriate components are determined and the system is implemented in the SIMULINK environment. The DC-link voltage is controlled by the battery which leaves the reference current provided to the inverter undetermined. This free parameter leaves room for optimization purposes. In this work an optimization for the electricity price is studied as nowadays variable price contracts and even spot price tied contracts are available on the energy market. Consumers could benefit of these types of contract when making use of a battery energy storage system. The results of this optimization and a full economic analysis of the system conclude this work. The full analysis furthermore discusses an optimal sized battery and inverter for given input parameters of the system. Finally a sensitivity analysis is carried out to study the effects of these parameters.
