Raza S. 57192673539 8136874200 57928298500 49561491700 56572184500 Electric power supplies to apparatus; Energy resources; Battery energy storages (BES); Exponential smoothing; Moving averages; Output fluctuations; PV smoothing; Ramp rates; Smoothing parameter; Solar PVs; Energy storage In this paper a new ramp-rate control strategy based on exponential smoothing (ES) method is proposed. Different from conventional ES, the proposed method varies the smoothing parameter �?� according to PV ramp-rate. The proposed smoothing parameter is used to determine the switching status of the battery energy storage (BES). It is also used in determining the amount of power to be injected or absorbed by the BES in order to smooth the PV output power. The proposed ramp-rate control strategy is compared with moving average (MA) and conventional exponential smoothing (CES) methods. It has been found that MA and CES method exhibit memory effect that caused BES to operate all the time. The proposed ramp-rate control strategy overcomes this limitation by operating the BES only during significant fluctuation. As a result, the size of the BES capacity can be reduced and increasing its life span. � 2017 Elsevier Ltd Final 2023-05-29T06:52:51Z 2023-05-29T06:52:51Z 2018 Article 10.1016/j.ijepes.2017.10.015 2-s2.0-85032859283 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85032859283&doi=10.1016%2fj.ijepes.2017.10.015&partnerID=40&md5=c896049975aa1f7573f40f03fa9fb024 https://irepository.uniten.edu.my/handle/123456789/23890 96 296 305 Elsevier Ltd Scopus |
