Modelling platform for control design purposes and large-scale power system studies

The main objective of this task is to conduct power system integration studies to establish control strategies and procedures that give hydropower plant with the proposed generator&converter technology robust Fault Ride Through capability and the ability to provide balancing and ancillary services to transmission system operators. A smart controller will be developed to enable conventional and converter-connected hydropower plants to provide the full range of AS including those with fast time-scales, such as synthetic inertia and dynamic voltage control, and those with slow time-scales, such as balance regulation and power gradient constraint.

Converter sizing and main circuit component selection for the application

The inverter for the hydro generator provides substantial new possibilities for a flexible driving of the whole electric drive train system, and accordingly the generator and the inverter will in this project be derived in parallel. For the power electronic converter, multilevel converters such as the NPC in a 3 and 5-level set-up, as well as a MMC set-up, are to be compared with a classical 2 level converter. Component selections will be made-, here the electric generator design plays an important role giving various amounts of reactive power needed and accordingly various sizes of the power electronic semiconductors. Apart from Si IGBT’s also the consequence of using SiC Mosfets will be investigated. The effect of the ripple induced by the switching on the inverter as well as on the dc-link capacitor, also accounting for the consequence of switching losses are to be investigated. Moreover, control algorithms fulfilling the requirements from WP2 will be derived. Finally the control speed of the inverter-generator system will be investigated for being utilized in various ancillary service actions, such as reactive power steps, and transition from generating power to absorbing energy for storing (.i.e. pumping power).

Intelligent control mechanisms for enhanced Fault Ride-Through performance and provision of Ancillary Services

The control strategies will ensure the secure operation under fault conditions, addressing issues such as system control under communication failure, faults in the HVDC system and faults in AC main grid.

Report defining three European energy scenarios

Three global – in a European scope – scenarios are defined with respect to different generation- and transmission-situations in the power system. Due to the importance of the scenarios for the subsequent work the entire consortium is involved incorporating the input of each partner. For this purpose, relevant parameters (e.g. percentage and profile of volatile producers, type and amount of installed storage, connection of Nordic grid to central European grid etc.) are identified first. Secondly, a meta-analysis of existing national and international scenario studies will be performed in order to get an overview within the European scope. Part of these scenarios will also be an estimate on how market prices for flexible operation and, thus, remuneration will evolve so that the financial revenue of highly dynamic hydropower plants can afterwards be evaluated in WP5.
