Analysis of an electric vehicle agent based management model
Abstract
An agent based control system that manages the charging of electric vehicle batteries according to distribution network constraints and electricity market price signals, is described. The system is adapted to the EV-ON platform and Microgrid equipment of Tecnalia-Lab. A case study is defined to evaluate the behaviour of the control system and the results are discussed. Uncontrolled Electric Vehicle (EV) battery charging is anticipated to modify voltage profiles of distribution feeders, overload transformers and cables, and increase power losses . The Multi Agent System (MAS) technology has emerged as a potential solution to manage dispersed energy resources in distribution networks. In this research, an MAS is proposed to manage the charging of EVs. This MAS comprises a hierarchical structure based on the European Union's (EU) project Mobile Energy Resources in Grids of Electricity (MERGE) . A description of the MAS and its adaptation to the EV-ON platform and Microgrid of Tecnalia-Lab is provided. A case study of the MAS operation is defined and the results are analysed. The MAS considers two entities: (i) the EV Supplier/Aggregator (EVS/A), which facilitates the participation of the EVs into the electricity markets and (ii) the Distribution System Operator (DSO), responsible for the technical operation of the distribution system. The aggregator's hierarchy consists of: the Regional Aggregation Unit (RAU) agent, located at the primary substation; the Microgrid Aggregation Unit (MGAU) and the Clusters of Vehicle Controllers (CVC) agents, located at the secondary substation; the Vehicle Controller (VC) agent. The DSO is represented by the Central Autonomous Management Controller (CAMC) agent located at the primary substation.
