This paper develops a system frequency response (SFR) model and proposes a control parameter design strategy, accounting for the communication-free frequency support of offshore wind farm (OWF) connected through high voltage direct current (HVDC) transmission system. By incorporating the power dynamics of OWF and HVDC during frequency disturbance, the traditional SFR model is extended to quantitatively evaluate the contribution of HVDC-connected OWF to onshore grid frequency dynamics. Furthermore, the control parameters to provide frequency support are optimally designed based on the extended SFR model by considering constraints on wind turbine power variation and DC voltage fluctuation. Compared to the works relying on detailed simulations, the salient novelty of the paper lies in the fast and accurate system performance analysis and control parameter design, ensuring efficiency and practicality for real-world applications. Comprehensive case studies in the PSCAD/EMTDC and the MATLAB/SIMULINK platforms demonstrate that the system frequency response characteristics can be evaluated accurately and improved significantly while satisfying the operational constraints.

The rise of inverters integrated into power systems has raised enormous concerns about potential system instability. This paper aims to investigate the correlation between phase-angle and voltage dynamics and their impacts on the stability of power systems, focusing on damping perspectives. To this end, we first formulate a generic model to unify the dynamics of synchronous generators and diverse inverter-interfaced devices. By exploring systems’ damping characteristics, we find that angle-voltage coupling tends to undermine stability by redistributing the system’s damping in a more dispersed manner, consequently rendering the system more vulnerable to inadequate or even negative damping. Our work also involves analyzing and quantifying the factors affecting coupling strength, including power flow, control parameters of devices, and the number of integrated inverters. A cross-loop control is also introduced to demonstrate the potential benefits of utilizing angle-voltage coupling to enhance stability. We validate these findings through simulations on a modified IEEE 39-bus system with heterogeneous inverters and other standard benchmarks with up to 500 buses. Simulations show the coupling’s impact on dispersing individual damping under 100% of the tested benchmarks. The rightmost eigenvalue shift varies from 20% to 80% under the coupling, which significantly influences the stability evaluation results. This comprehensive investigation yields insights into the complexities of angle-voltage coupling, which offers useful implications for the analysis and control of power systems.

Distributed generation in power systems is currently attracting significant attention as a means to reduce energy generation costs through the exploitation of low-cost decentralized sources. Cost reduction becomes especially relevant when a large portion of the energy supplied by a centralized generator is replaced by energy from a few high-power distributed sources. However, the effectiveness and safety of this approach critically depend on the proper allocation of distributed generators. To this end, this paper presents a novel sensitivity analysis for system losses that highlights the nonlinear dependencies on power-injecting sources. It is shown that the parameters of the nonlinear model allow easy identification of a small subset of grid buses that are suitable candidates for large-power injection. At these buses, source sizing can be determined using standard optimal power flow techniques that minimize the energy cost function. The proposed allocation strategy is validated on the IEEE 69 and 85 benchmark bus grids, and its robustness is further confirmed through simulations that account for stochastic load fluctuations. Comparison with state of the art and robust source allocation approaches, such as the Iterative Search Method, shows that for similar accuracy the proposed method is two/three orders of magnitude faster.
