“…Furthermore, the impact of an inverter should not be ignored in realistic applications. Authors in [32] capture the clipping effects when inverters reach the limit of converting DC power based on fuzzy logic. More harmonic components are generated in line with clipping effects, which further diminishes the performance overall of a PV system.…”

The high penetration level of photovoltaic (PV) generation in distribution networks not only brings benefits like carbon savings, but also induces undesirable outcomes, like more harmonic components and voltage fluctuations. Driven by decreasing costs of energy storage, the focus of this paper is to investigate the feasibility of applying energy storage in the grid-connected PV system to mitigate its intermittency. Firstly, to appreciate the functionality of storage, a generic PV-battery-supercapacitor model was simulated in MATLAB/Simulink, and a flat load profile was obtained to enhance predictability from the network management point of view. However, the usage of supercapacitors at the residential level is limited, due to its high startup costs. Secondly, a detailed residential PV-battery model was implemented in the System Advisor Model (SAM) based on local data in Dubai. The optimal sizing of a battery system was determined by assessing two criteria: The number of excursions, and average target power, which are contradictory in optimization process. Statistical indicators show that a properly sized battery system can alleviate network fluctuations. The proposed sizing method can be also applied to other PV-storage systems. Finally, economic studies of PV-battery system demonstrated its competitiveness against standalone PV systems under appropriate tariff incentives.

“…Moreover, it may be especially valuable in regions with aggressive renewable portfolio standards-and related solar carveouts, storage carveouts, and storage mandates-which provide an incentive for the recovery and utilization of otherwise curtailed PV generation (Gorman et al 2020;Ahlstrom et al 2019;DiOrio, Denholm, and Hobbs 2020;Denholm, Margolis, and Eichman 2017;Hledik et al 2019;Mai et al 2021).

“…In UK, PV plants present annual load factors close to 10% [2], which are calculated considering the rated power of the converter. A common practice is to increase annual plant factor by oversizing the power rating of the PV array, with respect to the converter [3]. The ratio between PV array rated power and the inter AC rated output power is known as Inverter Loading Ratio (ILR) [4]; in places with high irradiation variability such as UK, PV array power ILR oversizing can reach as much as 40%, whereas, in places with lower irradiation variability, such as central Chile, oversizing is closer to 15%.…”

Moreover, the continuous drop on PV module prices have encouraged the increase of ILR in PV plants [3]; some authors have even proposed ILR oversizing up to 80% [4].…”

Energy Storage Sizing Strategy for Grid-Tied PV Plants under Power Clipping Limitations

This paper presents an analyses of an Energy Storage System (ESS) for grid-tied photovoltaic (PV) systems, in order to harness the energy usually lost due to PV array oversizing. A real case of annual PV power generation analysis is presented to illustrate the existing problem and future solutions. Three PV modeling techniques have been applied to estimate non-measured non-harnessed PV power to provide an ESS energy and power sizing strategy. Moreover, a control strategy to store or release power from the DC-link, without modifying the Maximum Power Point Tracking (MPPT) strategy, is presented. The results show an estimation of the annual power loss caused by oversizing the PV array. The ESS sizing strategy gives insight into not only the energy requirements, but also the power requirements of the system. Simulation results show that the proposed ESS control strategy is capable of harnessing the extra power without modifying the existing power converter of the PV plant nor its control strategy.
