Value of Bidirectional V2G Smart Charging Responsive Services: Insights from a Simple CA Model

TL;DR

This paper uses cellular automaton models to evaluate how vehicle-to-grid (V2G) responsive services enhance the controllability of electric vehicle aggregators, revealing limited but valuable contributions.

Contribution

It introduces modified CA models to simulate V2G discharge/recharge capabilities and assesses their impact on system controllability.

Findings

V2G adds limited controllability to the system.

CA models effectively simulate load-sifting and V2G responses.

Results suggest modest benefits of V2G in system management.

Abstract

In this paper, particle-hopping cellular automaton (CA) models of elastic demand are used to investigate the value added to plug-in electric vehicles (PEV) aggregators by adopting vehicle-to-grid (V2G) responsive services. CA models used earlier to study load-sifting responses are modified to capture discharge/ recharge capabilities of V2G. Results on ramping responses from CA are then analysed to discuss the small contribution to system controllability added by V2G responsive services.
