Decentralized Based Advance Optimized Scheduling Scheme to Charge and Discharge the Electric Vehicles

Abstract

Electric vehicles are more and more became come out in power systems. Electric cars, including the quantity and duration of charging and discharging their batteries, will give exceptional improvements to the structure of power networks if they use Optimum Scheduling Schemes. The energy costs in the entire architecture of the power system can be gradually modified by paying in periods of low power costs and releasing in periods of high-power costs. In addition, in high-demand cycles in the power system it can be supported to satisfy the electricity demand. On the other hand, at a time when a thought about the vast population of electric vehicles could be influential in their ideal planning, multiple down to earth considerations including the battery life. However, the scheduling problem has 2 major future challenges. First, the challenge is to cut down cost using decentralized optimal scheduling solution. Second, it is arduous finding distributed scheduling scheme, can maintain huge population and EVs abnormal arrivals. Localized optimum scheduling, globally optimal scheduling, and locally optimal scheduling are three EV charging and discharge techniques presented in this research. At the start we delineate global scheduling optimization issue by optimizing charging forces to reduce the cost of EVs performing charging and discharging for a day. Decentralized optimal solution offers the absolute minimum cost. The globally optimal scheduling scheme, however, is not realistic because it entails details dependent on potential base loads from EVs, arrival times and charging times that will arrive in the future time of day. To build concrete scheduling schemes, we need to delineate the decentralized scheduling optimization in order to minimize the total cost of EVs in the current ongoing local community EV collection. Here, a distributed EV charging controller is developed to achieve “valley filling” (flattening demand profiles during nighttime charging), thereby fulfilling diverse individual charging requirements and addressing distribution network constraints significantly improved than others.
