This paper presents a real-time co-simulation platform aimed to test control strategies for the management of the interaction between a smart grid and active prosumers. The main feature of the proposed framework relies on the multi-site approach that allows the decoupling between the network model and the system under test. This allows separate testing with the exchange of a limited amount of information...
An intermittent nature of the solar generation affects the micro-grid system noticeably when the micro-grid is disconnected from the power system through a fault, etc., and islanding operation is compulsory forced. So as to prevent anticipated problems, batteries are sometimes used for compensating surplus and shortage of the PV power output fluctuation. Two kinds of battery connections have been...
Batteries are extensively used as small to medium range energy storage devices in smart grids. The estimation of the internal states of the batteries such as state-of-charge (SoC) is critical to provide consistent and efficient energy storage capabilities for the grids. In general, the electrochemical batteries are represented by non-linear mathematical models. Hence, the non-linear filters such as...
Battery 2nd life storage systems are a result of the synergies between the automotive and power generation sectors. They leverage the sustainability potential of electric vehicles (EVs) and renewable energy grid integration simultaneously. The vast experience of automobile manufacturers in battery system manufacturing and long-term operation in EVs provide a strong basis for replicating their success...
The rising penetration of intermittent power sources such as solar photovoltaic systems is a concern for electric utility operators, and techniques to mitigate the effect of power variability have been proposed. One method is to use electric vehicle (EV) batteries, connected through fast bidirectional chargers, as short time scale storage devices for intermittent power sources. This allows the high...
Several European projects on smart grids are considering Electric Vehicles (EVs) as active element in future power systems. Both battery-powered vehicles and plug-in hybrid vehicles are expected to interact with the grid, sharing their energy storage capacity. Different coordination concepts for EVs are being investigated, in which vehicles can be intelligently charged or discharged feeding power...
In order to make smart grid feasible, the respective (a) topology and (b) control infrastructure should be determined first for the low level of the grid, i.e. microgrids or even smaller grids like a residential in-house grid, and be expandable in a larger scale. Additionally, the experimental investigation of properly designed interconnected microgrids could simulate the behavior of the whole distribution...
The development of smart solar grids will help to provide concentration of power within the grid and eliminate the power losses seen when panels are working insufficiently. It will also allow switching between panels to provide optimal battery charging. Each panel will be characterized by their open circuit voltage and short-circuit currents. This paper presents approaches to implementation of this...
Renewable energy generation, vehicle electrification, and smart grids rely critically on energy storage devices for enhancement of operations, reliability, and efficiency. Battery systems consist of many battery cells, which have different characteristics even when they are new, and change with time and operating conditions due to a variety of factors such as aging, operational conditions, and chemical...
