Impact of batteries in the hosting capacity of a grid with photovoltaic generation

Abstract

This paper analyses the impact of batteries in the hosting capacity of a low voltage grid with prosumers with photovoltaic generation installed under different scenarios. Storage location in the grid has been selected with the criterion of reducing congestion. Two scenarios have been considered: the first with current demand of consumers in the grid and the second by increasing their demand profile proportionally, whilst maintaining the daily load curve shape, until a congestion situation is reached. Simulation of increasing PV generation and storage capacity is performed until a congestion is given, resulting for the first scenario an increase of 140% of PV production is achieved with 100kWh of storage. In the second scenario 230 kWp of maximum hosting capacity can be achieved with 400kWh of storage.
