Aggregated and distributed battery energy storage systems improve distribution grids operability by providing advanced energy management schemes and energy resources allocation. Charging over consumer’s peak power is one of the implementations of energy contracts that incentivize storage, even if it does not provide a direct interconnection between intermittent renewables and storage increasing its benefits. In this paper, an aggregated battery energy storage system is computed based on measured electrical power consumption patterns of a residential distribution network. Aiming to estimate the techno-economic factors that could potentially incentivize the installation of the battery system, the consumption patterns at both the transformer and the load side are analysed. The parameters that affect the economic viability of the system are evaluated in order to perform financial calculations about the profitability of the system.
