Electric vehicles (EVs) are playing an important role in power systems due to their significant mobility and flexibility features. Nowadays, the increasing penetration of renewable energy resources has been observed modern systems, which brings many benefits for improving climate change accelerating low-carbon transition. However, intermittent unstable nature sources introduces new challenges b...

Energy systems need a complete decarbonization within the next 20–30 years, calling for introduction of CO2-free renewable energy sources (RES). All final uses must face this challenge, now finally including transportation sector which should mostly be electrified. This option could constitute both challenge and an opportunity electric grid. In fact, connection to grid all vehicles (EVs) togeth...

The mitigation of peak-valley difference and transient power fluctuation are both great significance to the economy stability grid. This paper proposes a novel vehicle-to-grid behavior management method that can provide peak-shaving fast balancing service grid simultaneously. Firstly, multi-time scale framework is designed enable large-scale optimization real-time control at same time in schedu...

With the global net-zero strategy implementation, decarbonisation of transport by massive deployment electric vehicles (EVs) has been considered to be an essential solution. However, charging EVs and integration into electricity grids is going a fundamental challenge future systems. Hence, in this situation, how effectively deploy numbers EVs, meantime what can developed deliver vehicle-to-grid...

Two predominant areas of ongoing transport electrification are the uptake electric vehicles (EVs) in personal transportation and electrically powered trains for mass - both significantly increase demand stresses on power grid. In this research, a novel V2G application to support rail is proposed. A local network can reduce peak grid arising from electrified traffic enable brake energy recovery ...

Variability and uncertainty of wind power generation increase the cost of maintaining the short-term energy balance in power systems. As the share of wind power grows, this cost becomes increasingly important. This thesis examines different options to mitigate such cost increases. More detailed analysis is performed on three of these: flexibility of conventional power plants, smart charging of ...

The physical structure of the lab is shown in Figure 3. The plug-and-supply interfaces to which resources can be connected are marked in green. Starting from the feed-in, the ring connects a solar photovoltaics (PV) simulator shown in blue. It consists of a commercially available inverter and a solar panel emulated by a controllable electronic amplifier. Loads are shown in yellow. A single fami...

The integration of plug-in electric vehicles (PEVs) to power systems has impacts on the stability characteristics of the integrated systems. Wide area controllers (WACs) are used in power systems to provide auxiliary control signals to the generators or other devices in order to improve the stability of the system. The necessity of WACs becomes more relevant during grid-to-vehicle (G2V) or vehi...
