Overview of Storage System and EV Aggregation Charging Behavior in Energy Market

摘要

The Electrical vehicle (EV) technology is gaining popularity; it is because of many factors like reduction in carbon and green gas and usage of vehicle batteries as a storage element in the power system. However, the increasing usage of auxiliary loads i.e. EV and heat pumps creates adverse effects on the grid. Flexibility of power consumption due to uncertainty in modern day grid requires some storage elements. In this paper an overview of modern day grid is presented. Moreover the charging scheduling of Aggregators EVs battery is addressed. The mathematical formulation for generalization of EV, battery energy storage system (BESS) is presented with the constraints. Finally the case study for multi aggregator charging schedule generation is presented which can also be extended to a generalized modelling of storage system with different new energy sources in the future. The required results and the proposed mathematical modelling shows the effectiveness of the solution towards a more modern day grid friendly environment.
