Coordinated Control of EV Charging Stations for Grid Frequency Support Using Dual Droop Control Strategy Employed For VSC & DAB Converters888

Abstract
Battery technology and power electronic converters have facilitated the widespread use of Electric Vehicles (EVs), resulting in reduced rotational inertia and frequency stability of the power system. ... see moreTo address this issue, grid frequency support must be provided through various methods, including the regulation of power exchange between the grid and grid-tied inverter. Virtual inertia can be obtained from the energy stored in the DC link capacitors of the grid-tied VSC and the battery charging points. Coordinated droop control strategies from the VSC and EV charging ports can provide frequency support to the grid during disturbances. This session will discuss the use of EMTP® simulations to develop coordinated droop control strategies for mitigating frequency stability issues.

Development of a benchmark on EMTP for the test of grid forming power electronic converters785

Abstract
In the next years, the grid forming control will become a reality in the transmission grid. This a major milestone for the grid in order to be able to integrate even more power electronic converters a... see morend it represents also a major challenge. For doing so, the TSO will need to develop a bench mark to test the behavior of this new types of control. This presentation gives a first proposal of benchmark and give some example of the test on several types of grid forming controls. All the simulation model are developed on EMTP.
