Offer Description

The NO and CO2 emission reduction targets agreed in COP21 and the Paris Agreement are ambitious and require a profound transformation in society’s way of life and production. One of these transformations is the insertion of the electric vehicle since, the transport sector is one of the most polluting among human activities. The electrification of the transports generates several technical and technological challenges for the road, energy, and automotive industry. One of these challenges is the need to develop a charging infrastructure for these new vehicles. It is important to realize that electric vehicles are becoming a reality in several countries, in particular in Europe, where currently 20% new vehicle sales are electric.

At the same time, the electrical power system is currently undergoing a dramatic change from centralized generation to distributed generation. Most of these distributed/renewable-energy generators comprise variable-frequency Alternative Current (AC) sources, high-frequency AC sources, or Direct Current (DC) sources, and hence, they need power converters to interface with the public-utility grid that is currently in AC. The distributed generation is in addition often located in the low or medium voltage grids, who were not designed to integrate generation. Furthermore, most storage systems like batteries, supercapacitors and fuel cells are in DC, while modern loads like electric vehicles, computers, tablets and cell phones are also in DC.

MicroGrids, and in particular mixed AC/DC MicroGrids, are an interesting solution for the integration of electric vehicles, distributed/renewable sources, storage systems and modern loads. It is then expected in the future to see the rise of such MicroGrids with island capabilities. For this reason, it is capital to study the control and management of such DC and AC MicroGrids, in particular the possibility of using the DC one to provide ancillary services to the AC one. With the advent of different charging technologies, this scenario becomes more complex. Dynamic and semi-dynamic wireless charging stations, bi-directional and fast charging are some examples of the future charging infrastructure for all kinds of electric vehicles. In an urban scenario, these systems need to be integrated with the actual power grid infrastructure or a new one needs to be designed. On the other hand, electric vehicles provide storage capacity connected to the grid, and that may be used to support this grid, most likely in parallel to stationary storage systems. This support is particularly important concerning very fast ancillary services that are capital for the future electric grid.

Another important point in this future grid comes from the fact that the increase of power converters, and the interaction with DC MicroGrids, will continuously reduce the amount of inertia, ultimately leading to MicroGrids only composed of power electronics, and as a consequence, inertia-less. One of the most important challenges for systems with small amount of inertia like islanded MicroGrids is that they are more sensitive to system disturbances due to less stored energy to compensate energy imbalances and to slow the rate of change in frequency. In small power systems, individual generators tend to be large in comparison with the system size and the electricity demand. A loss of a generation unit is hence likely to result in a large percentage of imbalance in the power system. This all means that for example in the event of a sudden generator malfunction, the power system frequency will fall very quickly and there is a high likelihood of a power system black out.

The proposed work means to investigate how to use MicroGrids to connect electric vehicles charging (dynamic and static) to legacy power grid, to local distributed energy sources, storage systems, and the Smart City. The main goal is to stabilize and manage this grid based on the control of power inverters, and in particular MicroGrids, to provide inertia emulation and to help stabilizing the reduced inertia main AC grid. This is a strategic topic for future distribution grids and will allow their development aiming to mitigate the effect of future increase of DC elements as renewables, electric vehicles and storage systems like batteries and supercapacitors.

Therefore, the main topics addressed at this work are:

• Design of MicroGrids for interconnecting electric vehicles to the main grid

• MicroGrids control and stabilization

• New charging infrastructure technologies and their impact on the grid (dynamic wireless charging)

• Electric vehicles as a load, storage, and service provider

• Power electronics converters control

• Renewable energy power sources and energy storage integration in a MicroGrid

• AC, DC, and mixed MicroGrids
