Decentralized PEVs Energy Management Scheme for Supplementary Frequency Regulation Considering Mobility Behaviour

摘要

Need of reduction in CO₂ emissions and increased oil demand in automobile sector resulted in development of Plugin Electric Vehicles (PEVs). It has a rechargeable battery and can act as storage device. This mobile battery storage device is utilised to implement Vehicle 2 Grid (V2G) technology. In this paper, the mathematical model has been suggested to serve the grid in term of ancillary service such as frequency regulation. The regulation signal from PJM is used to simulate the proposed scheme. To meet the regulation signal effectively, thousands of PEVs have to participate in this scheme. So, the idea of the aggregator is integrated into the proposed scheme to control the fleets of PEVs. The regulation signal is used to determine the total charging and discharging power of PEVs to regulate the frequency. The results show the proposed scheme is able to meet the high negative regulation signal with G2V action due to availability of PEVs for charging. But it fails to perform properly during high positive regulation signal with V2G action due to unavailability of PEVs for discharging. The arrival of PEVs at the Charging Station (CS) is governed by mobility data of Korean Transportation Safety Authority.
