Abstract
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.

Summary
Photovoltaic (PV) generation is one of the most widely applied forms of renewable energy generation (REG), which converts universally available solar energy into electricity through the photovoltaic effect [1]. The whole generation process is nearly independent of fossil fuels, and the rapidly growing usage of PV technologies is in line with sustainable goals and renewable targets proposed worldwide. According to the World Bank, electric power consumption per capita in the United Arab. Emirates (UAE) is more than three times higher than the world average [3]. Massive PV projects are a promising solution to compensate the high energy budget, especially suitable for countries like the UAE, which is abundant in solar energy
