Abstract
Due to the increasing share of inverter-based renewable energy sources and the increased retrofitting of conventional hydropower plants with power electronics, novel possibilities arise for providing damping power in case of occurring inter-area oscillations in power systems. This paper presents a complete model of a variable-speed hydropower plant (VSHP) in a single-machine infinite bus system. The demonstrated analytical model is applied for small-signal stability analysis that contains all relevant converter dynamics and is verified by an additional non-linear time-domain simulation. The damping controller approach located in the full-size converter (FSC) consists of the classical power system stabilizer with additional phase compensation, to which an appropriate wide-area input signal is fed via a phasor measurement unit device. Subsequently, the FSC-VSHP with additional damping algorithm is examined with respect to the significantly higher damping performance with regard to inter-area modes in a three-machine model.
期刊介绍：
IET Generation, Transmission & Distribution is intended as a forum for the publication and discussion of current practice and future developments in electric power generation, transmission and distribution. Practical papers in which examples of good present practice can be described and disseminated are particularly sought. Papers of high technical merit relying on mathematical arguments and computation will be considered, but authors are asked to relegate, as far as possible, the details of analysis to an appendix.
The scope of IET Generation, Transmission & Distribution includes the following:
Design of transmission and distribution systems
Operation and control of power generation
Power system management, planning and economics
Power system operation, protection and control
Power system measurement and modelling
Computer applications and computational intelligence in power flexible AC or DC transmission systems
Special Issues. Current Call for papers:
Next Generation of Synchrophasor-based Power System Monitoring, Operation and Control - https://digital-library.theiet.org/files/IET_GTD_CFP_NGSPSMOC.pdf
