Assessing the viability of battery energy storage systems coupled with photovoltaics under a pure self-consumption scheme

Abstract

Over the last few decades, there is a constantly increasing deployment of solar photovoltaic (PV) systems both at the commercial and residential building sector. However, the steadily growing PV penetration poses several technical problems to electric power systems, mainly related to power quality issues. To this context, the exploitation of energy storage systems integrated along with PVs could constitute a possible solution. The scope of this paper is to thoroughly evaluate the economic viability of hybrid PV-and-Storage systems at the residential building level under a future pure self-consumption policy that provides no reimbursement for excess PV energy injected to the grid. For this purpose, an indicator referred to as the Levelized Cost of Use is utilized for the assessment of the competitiveness of hybrid PV-and-Storage systems in the energy market, considering various sizes of the hybrid system, battery energy ✩ This research has been co-funded by the European Union and National Funds of the participating countries through the Interreg MED Programme, under the project "Promotion of higher penetration of distributed PV through storage for all -StoRES".

Shared Solar and Battery Storage Configuration Effectiveness for Reducing the Grid Reliance of Apartment Complexes

“…In a time-of-use tariff market, this could become a good case since consumers usually prefer to schedule electricity usage during an economically advantageous tariff time interval. These results corroborate that adequate battery capacity with PV yields high self-sufficiency [45]. Li-ion technology facilitated in providing higher self-sufficiency targets [44], which resulted in reduced grid usage [38,48].…”

“…DRES in residential systems have been widely investigated in the literature with the primary intention to mitigate grid usage and increase self-consumption [38,41] and self-sufficiency [37,39,44]. In this regard, the role of battery storage in maximizing self-sufficiency and grid usage reduction has been widely considered as the primary objective [45].…”

A Cross-European Analysis of the Impact of Electricity Pricing on Battery Uptake in Residential Microgrids with Photovoltaic Units

“…Studies find that there is either no economic benefit of integrating ESS with PV at a household level in the UK [15] and Ireland [16], or it can only succeed for relatively small storage size [17], a low price of batteries [18] in Germany, but with optimistic prospect under assumptions of higher retail electricity prices [19]. These results are contradicted by an analysis for Cyprus, which finds that the addition of batteries is beneficial especially to large and medium prosumers [20]. In Portugal, demand response has been found to have better impact on the system's economic performance, than batteries [21].…”

An Optimal Methodology for Sizing and Selection of Battery Energy Storage System in Standalone Solar Pv Systems / Uma Metodologia Ótima Para O Dimensionamento E Seleção Do Sistema De Armazenamento De Energia De Bateria Em Sistemas Solares Fotovoltaicos Autônomos

“…( Barzegkar-Ntovom et al, 2020) evaluates the economic viability of a hybrid gridconnected PV-storage system for residential applications under a pure self-consumption scheme where no compensation is provided for injecting excess PV energy into the grid. (Vonsien and Madlener, 2019) presents the economic modeling of the economic efficiency of Li-ion battery storage where the increase in self-consumption of electricity from a solar PV system by means of a home battery storage system is quantified using a hybrid model which is a combination of a self-developed economic model and a technical battery-aging model.…”
