SMART LOAD SCHEDULING STRATEGY UTILISINGOPTIMAL CHARGING OF ELECTRIC VEHICLES IN POWERGRIDS BASED ON AN OPTIMISATION ALGORITHM

Abstract

One of the main goals of any power grid is sustainability. The given study proposes a new method, which aims toreduce users’ anxiety especially at slow charging stations and improve the smart charging model to increase the benefits for theelectric vehicles’ owners, which in turn will increase the grid stability. The issue under consideration is modelled as anoptimisation problem to minimise the cost of charging. This approach levels the load effectively throughout the day by providingpower to charge EVs’ batteries during the off-peak hours and drawing it from the EVs’ batteries during peak-demand hours ofthe day. In order to minimise the costs associated with EVs’ charging in the given optimisation problem, an improved version ofan intelligent algorithm is developed. In order to evaluate the effectiveness of the proposed technique, it is implemented onseveral standard models with various loads, as well as compared with other optimisation methods. The superiority and efficiencyof the proposed method are demonstrated, by analysing the obtained results and comparing them with the ones produced bythe competitor techniques
