Production and Operations Management · 2018

Key Findings

01A mixed rental-trading strategy for EV fleets in VPPs can be profitable for fleet owners.
02EV VPPs can reduce wind power curtailment, offering ecological advantages.
03Integrating EVs into VPPs can lead to reduced energy expenses for consumers.
04Fourier series accurately capture car-sharing demand patterns when weighted with asymmetric payoffs.

Application

Design takeaway

Designers of fleet management systems and EV charging infrastructure should integrate VPP functionalities to enable dynamic energy trading and optimize revenue generation for fleet operators.

How to apply

Fleet operators can explore partnerships with energy providers or VPP aggregators to monetize the idle time of their EV fleet by offering grid balancing services.

Project actions

01Investigate the potential for vehicle-to-grid (V2G) technology in your design project.
02Consider how dynamic pricing in energy markets could influence user behavior or product design.
03Explore business models that leverage underutilized assets for additional revenue.

Method & Evidence

AimWhat is the optimal strategy for managing an electric vehicle fleet within a Virtual Power Plant to maximize profitability by balancing grid service provision with vehicle rental demands?

MethodSimulation and Optimization

ProcedureA simulation model was developed to represent a fleet of 1500 electric vehicles. The model incorporated realistic demand patterns for car-sharing, using a Fourier series approach. An optimization strategy was employed to manage charging, discharging to the grid, and rental availability, considering dynamic pricing on an electricity spot market and the spatial preferences of renters. The model was evaluated on a North European electricity market.

ContextElectric vehicle fleet management, smart grid operations, energy markets

Variables

IV["Fleet management strategy (rental vs. grid discharge)","Electricity prices (dynamic)","Rental demand patterns"]

DV["Fleet profitability","Grid balancing effectiveness (e.g., reduction in wind power curtailment)","Customer energy expenses"]

CV["Fleet size (1500 EVs)","EV charging/discharging capabilities","Market structure (Nord Pool Spot)"]

Strengths & Limitations

Strengths

+Realistic simulation of EV fleet dynamics.
+Inclusion of both economic and environmental factors.
+Application to a real-world electricity market.

Limitations

The complexity of real-world energy markets and EV charging infrastructure can be difficult to fully replicate in a design project.

Reliability & validity

The study uses a simulation based on real-world data and market conditions, enhancing its validity. The use of Fourier series for demand modeling suggests a robust approach to capturing patterns. Reliability would depend on the accuracy of the input data and the stability of the simulation parameters.

Think critically

How might the 'location matters' aspect of rentals conflict with the 'location doesn't matter' aspect of grid discharge, and what design solutions could mitigate these conflicts?

Design Principles

"Maximize asset utilization by integrating distributed energy resources into broader grid management strategies."

This research highlights a novel approach for fleet operators to generate additional revenue streams beyond traditional rentals. By leveraging parked EVs as a distributed energy resource, businesses can contribute to grid stability and renewable energy utilization, creating a more sustainable and economically viable operation.

What This Means for Your Design

Electric cars that are part of a rental fleet can make money for their owners not just by being rented, but also by selling electricity back to the power grid when they are parked. This helps balance the electricity supply, especially when renewable energy sources like wind are involved.

How to use in your project

1.Reference this study when discussing the economic viability of electric vehicle adoption or fleet management strategies.
2.Use the findings to support arguments for incorporating smart grid technologies into product designs.
