Participation of storage devices for steady-state voltage management in LV grid with PV integration

International audienceThis paper focuses on the implementation of two main solutions (reinforcement and energy storage systems) in a low-voltage (LV) network with an important photovoltaic (PV) integration. The electrical network considered is a rural low voltage network which includes 20 clients and its PVs. The study is carried over 30 years with constant consumption and a rate of installation of PVs set to 3%. The model uses a Monte Carlo approach to model consumption and PV production. It can determine a planning of reinforcement and also the power of batteries needed to prevent overvoltage. The results indicate that energy storage systems have more benefits than reinforcing cables in this particular situation. Sensitivity analysis have been performed on different parameters which show the different conditions where reinforcement can compete with energy storage systems
