“…The OTS control is based on what manufacturers provide as general description of the basic operating principles and corresponds to the following: when generation exceeds demand, the BES system charges from all the surplus PV generation. When PV generation falls below the household demand, the BES discharges to meet the local demand [5]. This is demonstrated in Fig.…”

“…) is dependent on the demand and PV profile of each customer. For each customer, the methodology found in [5] was used to define the BES profile for the OTS control, and in [11] for the AD control. The BES systems are sized at 5kW/13.5kWh with 100% depth of discharge and 88% roundtrip efficiency.…”

“…However, existing self-consumption controllers embedded in commercially available BES systems, hereafter referred to as off-the-shelf (OTS), are ineffective in this matter providing little to no benefits to reverse power flow reduction. As demonstrated in [5], on a sunny day with no one at home, OTS BES systems start charging from the excess PV generation relatively early in the morning, quickly reaching full state-of-charge (SOC) even before high levels of PV generation occur. Consequently, given that the OTS BES system cannot store more PV generation after that time, the excess PV generation will be fed back to the electricity network.…”

“…However, [10] assumes that households with PV only or with a PV/BES system will not export into the grid at all times. As shown in [5], both these types of customers can export large amounts of PV generation into the grid, and therefore the effect that this can have at a system level as PV penetration increases needs to be assessed. This can lead to an underestimation of system costs as PV penetration increases; due to aggregated exports displacing baseload generation during midday.…”

The declining cost of residential battery energy storage (BES) and photovoltaic (PV) systems enable customers to significantly reduce their energy dependency from the grid. By absorbing excess PV generation, BES systems could reduce impacts associated with the 'duck curve'. However, since off-theshelf (OTS) BES systems are controlled for customer benefits, this absorption might be limited at times, resulting in similar duck curve effects. This work proposes a bottom-up modelling approach to demonstrate the system-level generation cost effects from residential BES systems. Using a modified IEEE 9-bus system with real anonymized smart meter data, results show that with the OTS BES control, the overall reduction in system net demand due to peak PV generation still occurs which leads to baseload generation shutting off, incurring additional costs. Alternatively, the adoption of smarter BES controls aimed at mitigating impacts on distribution networks by reducing PV exports can bring significant system-level generation cost reductions.

“…Os fabricantes fornecem apenas descrições gerais relacionadas aos princípios operacionais básicos de seus produtos. Assim, com base nos princípios operacionais mais comuns dos sistemas de armazenamento comercial, bem como nas informações encontradas na literatura (Petrou et al, 2018), este estudo pressupõe que os SAEB carreguem com base na geração fotovoltaica excedente (geração líquida Pgrid positiva) e descarreguem quando a demanda Pd for maior que a geração Pg (geração líquida Pgrid negativa). Tal estrutura de controle está descrita no Algoritmo 1 (Petrou, 2019):…”

In the current scenario, the increasing penetration of microphotovoltaic distributed generation (MPVDG) in the low voltage distribution networks (LVDNs) has caused technical problems, such as reverse power flow, voltage fluctuation and overvoltage. The overvoltage issue occurs due to the high LVDN R/X ratios of cables associated with active power injection by MPVDG. Such problems, in turn, have generated financial losses for both utilities and residential consumers. In the technical literature, emerging technologies and equipment, such as smart inverters with advanced Volt-VAr and Volt-Watt functions and battery energy storage systems (BESS), rise as potential solutions to mitigate the mentioned problems. This article comparatively evaluates the performance of Volt-VAr and Volt-Watt control techniques and a residential BESS charge/discharge control, highlighting the potential and limitations of each technique. The simulations are performed in a real LVDN. Time-series power flow simulations evaluate the mitigation techniques.
