An aggregator acts as a mediator between the system operator and residential customers, enabling mutually beneficial coordination for electric vehicle (EV) owners and the power system. The aggregator aims to maximize its profits from trading energy and regulation reserve in wholesale markets. Since the aggregator does not own EV batteries, the EV owners must be reimbursed for the degradation of their...
Without demand-side management, an increase in the number of electric vehicles (EVs) could result in overloads on distribution feeders. Aggregators could optimally manage the charging/discharging of the EVs, to not only maximize the consumers' welfare in response to real-time prices and accommodate their needs for transportation, but also to keep the distribution network within its operating limits...
This paper proposes a new transmission-constrained unit commitment method that combines the cost-efficient but computationally demanding stochastic optimization and the expensive but tractable interval optimization techniques to manage uncertainty on the expected net load. The proposed hybrid unit commitment approach applies the stochastic formulation to the initial operating hours of the optimization...
For a successful rollout of electric vehicles (EVs), it is required to establish an adequate charging infrastructure. The adequate access to such infrastructure would help to mitigate concerns associated with limited EV range and long charging times. Battery swapping stations are poised as effective means of eliminating the long waiting times associated with charging the EV batteries. These stations...
Integration of renewable generation is crucial in future generation mix of power systems as many are the benefits that it offers. At certain penetration levels, latent risks could materialize as a result of not adequately managing the additional variability, therefore this situation prompts the necessity of enhancing traditional tools to operate power systems. In this paper a sensitivity analysis...
It is expected that electric vehicles (EVs) will soon represent a large share of the demand for electricity. Several research works have extolled the advantages of these devices as flexible demands, not only to charge their batteries when it is cheaper to do so, but also to provide services in the form of vehicle-to-grid (V2G) power injections to the system. These services, however, could reduce the...
Electric vehicles' (EVs) penetration is expected to grow rapidly in the near future due to their low operating costs and low emissions as compared to conventional, fossil-fuel-powered vehicles. It is therefore essential for utilities to be equipped with the necessary tools to investigate the impact of these devices in their system well in advance. Since the operation, plug-in timing and energy consumption...
In response to the need for the decarbonization of the transport sector, it is expected that large fleets of electric vehicles (EVs) will constitute an important share of the electricity demand. This evolution is likely to be accompanied by a parallel evolution of the electricity supply business with the deployment of smart grid technologies. As a consequence, it is expected that demand will feature...
There is a growing body of evidence demonstrating how large penetrations of wind power generation in power systems contribute to increase the cost and the complexity of grid operations. Those costs and increased complexity are directly linked to the random nature of the wind over time, which requires system operators to carry more reserve capacity to cope with that randomness if current security and...
