POET Structured energy management and efficiency improvement of a grid-integrated electric vehicle energy Charging Stations

Abstract

Sustainable energy supply plays a pivotal role in the successful deployment of electric vehicle charging station (EVCS). The EVCS’s daily operation is governed by the availability of resources to meet the energy requirements without any load rejection. Developing countries have now turned to renewable energy powered vehicles to reduce their dependency on fossil fuels. They have been successful in their attempts to deploy EVCS in their respective countries whilst constantly working on the improvement of this infrastructure. However, the same cannot be uttered in South Africa. The county has limited power-generating capacity, which limits it capability of fully sustaining the existing load. An additional burden on the already ailing grid could have dire consequences on the local grid. Load shedding is imposed on customers as a temporary solution in order to avoid imminent blackouts. Conversely the ever increasing fossil fuel prices threatens the livelihood of an ordinary citizen. As an increase in this resources leads to an increase in transportation cost and food prices. To combat this problems, an efficient, sustainable and cost effective electric vehicle charging station that will be beneficial to the grid as well as the environment is necessary. POET (performance, operation, equipment and technology) energy efficiency improvement and management framework is utilized as an effort to analyse and initiate a feasibility and sustainability of the system to be implemented, by holistically looking at the performance, operation, equipment as well as technology. The afore mention POET energy efficiency improvement and management will look into the two of the three processes, namely targeting and planning in fourth level: An engineering level as an attempt to improve the efficiency and economical nobility of the system. A review in to the impact of technological advancement, of the proposed grid-integrated hybrid peer to peer electric vehicle energy sharing at a Charging Station in South Africa will be conducted.
