Nonetheless, electric vehicles can also provide supports to the power grid through Vehicle-to-Grid application by discharging battery energy into the power grid. This paper presents an optimal priority-based Vehicle-to-Grid scheduling with the objective to minimize the grid load variance. An optimal strategy was developed to optimize the amount of charging/discharging power based on the electric vehicle battery's state-of-charge. This study desires to find a central point which can benefit power utility and electric vehicle users. The algorithm can operate in three modes, which are valley filling, peak load shaving and priority charging. The charging of the electric vehicle can be performed in all three modes, as long as the charging of electric vehicle is required. Meanwhile, discharging of the electric vehicle only occurs during peak load shaving mode. To ensure the practicability of this study, numerous constraints were considered and the study was conducted in a commercial-residential area with electric vehicle mobility of 1300. The results indicated that the algorithm was able to minimize the grid load variance while prioritizing the electric vehicle with a low percentage of state-of-charge. The original maximum variation between peak loading and off-peak loading measured at 5 MW was effectively reduced to 1.5 MW following the deployment of the proposed algorithm. � 2021 Elsevier Ltd Final 2023-05-29T09:06:55Z 2023-05-29T09:06:55Z 2021 Article 10.1016/j.est.2021.102607 2-s2.0-85105306297 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85105306297&doi=10.1016%2fj.est.2021.102607&partnerID=40&md5=f6035fa9512d13e3098e0914778aeb1d https://irepository.uniten.edu.my/handle/123456789/26117 39 102607 Elsevier Ltd Scopus |
