The interest in electric vehicles (EVs) is rapidly increasing, and the upward trend seems to continue also in the future. As a result of the increasing energy consumption, the grid infrastructure has to be developed further, and moreover, it is necessary to analyze the network effects of the electric vehicle charging. In this paper, the challenge is approached by an actual case area in Finland and...
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...
For a large-scale introduction of electric vehicles (EVs) intelligent charging strategies are needed to adjust their energy demand to the production of renewable energy and the current load in the distribution grids. This paper presents an approach that puts the intelligence needed into the EVs, where most of the crucial information arise, thus minimizing the need of communication throughout the grid...
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....
This paper proposes an operating framework for aggregators of plug-in electric vehicles (PEVs). First, a minimum-cost load scheduling algorithm is designed, which determines the purchase of energy in the day-ahead market based on the forecast electricity price and PEV power demands. The same algorithm is applicable for negotiating bilateral contracts. Second, a dynamic dispatch algorithm is developed,...
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...
Plug-in electric vehicles (PEVs) represent both a new challenge for and a huge potential resource to the smart-grid. The secret to effective integration of renewable energy generation into the smart-grid is integration of enough storage to deal with the intermittency of the generation. However, there are several barriers to integrating enough storage to effectively harness renewable energy in the...
The current Renewable Energy Target (RET) of 20% renewables by 2010 commits Australia to a progressive introduction of renewable generation over the next 10 years. Due to the inherently intermittent nature of supply, this will require careful planning for efficient integration into the existing grid. It is shown that at an introduction rate of only 2% per annum, Electric Vehicles could provide sufficient...
It is mentioned that one million plug-in hybrid and electric vehicles will be on the road by 2015 in United States to reduce emission. If one million electric vehicles (EVs) are connected to the existing electric grid randomly, peak load will be very high. Electrified transportation based on a traditional thermal power system will be costly economically and environmentally though it has a great value...
