This study assesses the technical and financial impacts on voltage levels, peak demand, and technical losses of distribution systems due to the integration of battery energy storage systems (BESSs) associated with photovoltaic distributed generation (PVDG). It assumes that the BESS features (location and storage capacity) are chosen by consumers individually, aiming to directly benefit themselves according to self-consumption and price arbitrage uncoordinated control strategies. Computational simulations of several PVDG/BESS penetration levels in residential feeders of a Brazilian utility were performed via OpenDSS, employing real data of the load (consumption and load profiles) and photovoltaic generation (irradiance and temperature). We address the PVDG/BESS locations and the selection of solar irradiance, temperature, and load profile based on the Monte Carlo method. As the impacts on voltage levels, peak demand, and technical losses are expressed in different units, they were stochastically converted into monetary amounts to identify the control strategy that enhances the technical benefits in the distribution system. The results show that BESS installation with location, size, and control strategy defined by consumers creates technical benefits for the distribution system. The risk analysis allows us to conclude that price arbitrage should be prioritized in deciding incentives for penetration levels of up to 60%. Above these levels, self-consumption should be prioritized as an incentive. However, it is worth mentioning that the two strategies could be encouraged regardless of the penetration levels, as both create technical benefits for the distribution networks. The proposed method can support policy proposals to encourage BESS integration in distribution systems.

“…The trigger value was calculated by employing an optimization method based on the grid voltage sensitivity. The authors of [25] compared the impacts of uncoordinated and coordinated control strategies on voltage levels and energy selfconsumption. Both strategies aimed at supporting voltage regulation by assigning random values to the size of the BESSs.…”

“…Solar photovoltaic (PV)‐based distributed generation systems have been predominantly used for electrical energy generation around the globe in recent years due to their less carbon release, low fuel cost, less maintenance cost and high efficiency. Therefore, the use of a solar PV system is increasing rapidly in small industries and institutions at distribution end to compensate for the high electricity charges during peak hours [1]. The installation of the new roof‐top PV system‐based ancillary services comes good for system operators in terms of reducing losses and improving the power quality (PQ) when supplying local AC loads.…”

“…Energy Storage Systems (ESSs) are key elements in electrical systems especially in hybrid systems or smart grids. They allow for increased integration of renewable energy sources connected to the grid [18,24] as well as to increase reliability, stability and resilience of various systems [3,10,15,17,19]. There are several kinds of ESSs technologies such as: Pumped Hydro Storage, Compressed-Air Energy Storage, Battery Energy Storage (BES), Capacitor Storage, Super-Capacitor Energy Storage (SCES), Super-Conducting Magnetic Energy Storage, Thermal Energy Storage, Hydrogen Energy Storage (HES), and Flywheel Energy Storage.…”

This paper presents an original sizing method for Energy Storage Systems (ESS) based on directly matching their capabilities-as specified by their energy-power Safe Operation Area (SOA) in the Energy-Power (EP) plane-with the energy and power demand required to accomplish their missions. Starting from the system requirements and from an energy management strategy, the power demanded by a set of representative operating scenarios and its associated energy are calculated and represented as trajectories in the EP plane. The objective is to size the ESS such as its SOA contains these trajectories. Comparison between different technologies of Energy Storage Devices (ESDs) is possible using this SOA characterization. Special attention should be paid to compare specific SOAs across devices. Diverse energy management strategies can be synthesized in the EP plane where they can be compared and analyzed. The sizing method converges extremely fast and is suitable for its integration in an optimization loop. The method allows to determine directly and efficiently the technology and the size most appropriate (in terms of indicators such as mass or cost) to a given EP demand. In the paper, three different technologies (SuperCapacitor, Li-Ion and H 2 /O 2 batteries) are characterized and compared in terms of sizing synthesis.
