Aggregators in smart grid are business operators providing services to aggregate and visualize electricity information, balance demand and supply, reduce energy consumption, and do the other activities with Energy Management Systems (EMSs). An aggregator for Apartment Building Energy Management Systems (Apartment-BEMSs) balances demand and supply considering all households in its building. The buildings...
We propose the vehicle-originating-signals (VOS) approach for charging control of a fleet of electric vehicles (EVs) in an electricity distribution network (DN). The goal of the approach is to manage the EV load such that the aggregate power consumption, including inflexible demand and solar generation, closely follows a given target profile. The VOS approach enables EVs in a fleet to compute signals...
We propose and benchmark a new approach for electric vehicle charging control to match arbitrary power profiles. The approach enables vehicles to compute signals reflecting their need for charge and willingness to supply power. An aggregator collects these signals and implements the control with minor computational effort. We benchmark our approach against a centralized optimization, focusing on the...
Integrating electric vehicles (EVs) into future smart power systems is challenge and opportunity in one. Achieving system optimization, renewables integration and quick diffusion requires coordination of EVs with the power system. This paper analyzes price differentiation as a means to incentivize smart EV operation. For smart EV operation time, location and volume are important dimensions of price...
The objective of this paper is to present a double-layer charging control model which can be utilized by an Electric Vehicle Supplier/Aggregator (EVS/A) for scheduling and managing the electric vehicle (EV) charging demand. The first layer is a cost-minimization load scheduling algorithm considering the EV demand forecast and wholesale prices. EVS/A can be incentivized by the DSOs to offer load management...
The paper presents an agent-based scheduling and energy management system for a smart distribution feeder which is installed on a test site and includes an electric car sharing fleet. Distributed Energy storage systems provide flexibility in the operation of the test site, where the integration of multiple power sources including Renewable Energy Sources and Distributed Generators is implemented....
Photovoltaic generation (PV) output power varies depending on the time, weather, and season. Especially, PV output power can be low in the night or under bad weather conditions. In these cases, an electric vehicle (EV) battery can serve as a substitute for the storage system, and enables to attain in-house generation power continuously regardless of these bad conditions. In this study, we constructed...
There is much interest regarding the future possibilities - and risks - arising from integrating increasing numbers of plug-in vehicles with power system network operations, in particular demand-side management. There has been comparatively less enthusiasm directed towards addressing the question of what can and cannot be done with existing technology. This paper discusses what could be achieved and...
