Three aspects of Subsynchronous Resonance (SSR) related problems in power systems are addressed in this dissertation which aims at contributing to a better understanding of these problems. Subsynchronous Resonance (SSR) problems in series compensated steam-turbine power systems co-exist with the beneficial effects provided by the series capacitors. Since the early 1930s, numerous researchers have addressed issues relating to these problems. The development of a generalized frequency scan method for analyzing SSR in a Single-Machine Infinite-Bus (SMIB) power system equipped with fixed series capacitor compensation is presented. This method overcomes shortcomings present in the traditional frequency scan technique which is widely used in power system analysis. It has been noticed that there are nonlinear dynamic phenomena in power systems which can not be explained by linear system theory. This includes limited oscillations in a power system when it experiences SSR at a frequency close to one of the system modes. The phenomenon can be explained by Hopf bifurcations. This dissertation presents an analysis for a high dimensional model of a SMIB power system equipped with fixed series capacitor compensation. The results obtained can lead to a more precise understanding of this phenomenon than those available to date which use perturbation methods and highly simplified second-order power system models. Compared with fixed series capacitor compensation in power systems, the newly developed Thyristor Controlled Series Compensation (TCSC) scheme has some well known advantages with regard to flexible power system control. It has been noted that vernier mode TCSC operation can provide for SSR mitigation. In this thesis, such beneficial effect is demonstrated and analyzed for a simplified North-Western American Power System (NWAPS) model, based on EMTP simulations. Issues relating to modelling and simulation of power system and TCSC are addressed.

Conventionally transmission line power transfer capability can be increased by inserting the series compensation into the transmission lines. Though series compensation is an economical solution compared to building a new transmission line, it brings the risk of Sub-Synchronous Resonance in turbine-generator system-based power plants. In literature mitigation of SSR was actively studied using wind turbine generators and FACTS devices, where certain type of WTGs is vulnerable to SSR and FACTS devices are expensive and are not capable to exchange active power with the grid. The structure of PV farms can bring the can bring the capabilities of WTGs and FACTS devices together while addressing their problems at the same time. Among different renewables wind and solar are the fastest growing, according to DOE SunShot initiative studies by 2050 solar serves an estimated 27% of the U.S. electricity needs. The rapid growth in utility connected PV farms has opened new possibilities, and due to its flexibility and dispatchability PV farms can handle the grid support functions more effectively, whereas its ability to mitigate the SSR is rarely investigated. This thesis addresses the potential of PV Power Station to mitigate SSR problem particularly torque amplification in series compensated systems by augmenting the GSC control loop with damping controller using a control signal which is closely related to the network resonant mode, utility scale PV farms are a promising solution to combat the increasing demand and grid support functions simultaneously. The simulation studies are performed in MATLAB/Simulink software using IEEE Second Benchmark Model (SBM) for SSR studies.

This relevant and timely thesis presents the pioneering use of risk-based assessment tools to analyse the interaction between electrical and mechanical systems in mixed AC/DC power networks at subsynchronous frequencies. It also discusses assessing the effect of uncertainties in the mechanical parameters of a turbine generator on SSR in a meshed network with both symmetrical and asymmetrical compensation systems. The research presented has resulted in 12 publications including three top international journal papers (IEEE Transactions on Power Systems) and nine international conference publications, including two award-winning papers.
