چکیده
This article explores the potential impacts of integrating electric vehicles (EVs) and variable renewable energy (VRE) on power system operation. EVs VRE are integrated in a production cost model with 5 min time resolution multiple planning horizons to deduce effects generation EV charging operating costs, dispatch stacks, reserves curtailment. penetration scenarios light-duty vehicle fleet 10%, 20%, 30% considered RTS-GMLC test system, is 34% annual consumption. The investigated during peak summer four weeks year which high low loads lead overgeneration. Uncoordinated coordinated considered. In uncoordinated scenario, undertaken at convenience owners, modeled using data from Idaho National Laboratory’s Project. Coordinated uses an “aggregator” model, wherein scheduled minimize costs while meeting daily requirements subject availability constraints. results show that each level, were higher than costs. During high-VRE, low-load week, (3% penetration), load increased by as much 27%. Using charging, shifts hours prices, coincident either load, VRE, or both. Furthermore, substantially reduces curtailment PV nine times seasons, wind more half season, compared no charging. cycles, forecasts, “look ahead” period scheduling dispatching units was crucial creating utilizing flexibility

Different Electric Vehicle Charging Strategies to avoid Reducing the Insulation Oil Lifetime of Distribution Transformers
Abstract: The widespread presence of uncontrolled electric vehicles causes overloading of distribution network equipment. One of these equipments is distribution transformer, which should pay attention to overloading and reducing lifetime of this equipment due to charging of electric vehicles. First, strategies have been proposed to investigate the effect of electric vehicle penetration level a...
متن کاملElectric Vehicle Charging Modeling
With an electrified passenger transportation fleet, carbon dioxide emissions could be reduced significantly depending on the electric power production mix. Increased electric power consumption due to electric vehicle charging demands of electric vehicle fleets may be met by increased amount of renewable power production in the electrical systems. With electric vehicle fleets in the transportati...
متن کاملMetaheuristic Optimization of Electric Vehicle Charging Strategies in Uncertain Environment
Probabilistic power flow studies form essential investigations for both operation and analysis of electric power grids under stochastic conditions. Especially the increasing penetration of intermittent and non-dispatchable power plants like wind power plants cause probabilistic behaviour at the supply side. At the same time, the expected penetration of electric mobility at the demand side compl...
متن کاملOptimization of Power Flow Through Electric Vehicle Charging
In order for charging companies to make the most profit from electric vehicle charging, costs and profits must be optimized. One way of doing so is by optimizing the power flow. For a charging station, power is either flowing in or out. Thus, power is being purchased or sold. The objective of this research is to optimize the profits made from this process. To do so, the average power demanded o...
