Abstract: This work has outlined the model for the optimal placement of storage devices in low-voltage grids. The CIGRE low voltage benchmark is used as a case for fixing the optimal location and storage sizing devices. The purpose is to increase the renewable energy sources in the local area network with all grid problems. The identified problem is a mixedinteger quadratic program with an objective function equal to total annual costs. The costs include annualized investments in storage devices, operation and maintenance costs and electricity cost-electricity and network losses. This work considered the variations in energy production and consumption by using daily variation curves for each month of the year. The experimental procedures prove that the storage devices, when placed, help increase the use of renewable energy sources, besides bringing the cost down.

Keywords: Storage Devices, Power Systems, Low-Voltage Grid, Photovoltaic, Optimization Reduced Energy Consumption in Low Voltage Networks
