“…where M i is the inertia, P mi is the prime power, P gi is the electrical power, D i is the damping constant, δ i is the rotor angle, and ω i is the frequency derivation (away from the synchronous frequency ω 0 ). Should the generator have a prime mover, the mechanical power P mi is the output of a second-order turbine/governor model [34]:…”

A novel wide-area control design is presented to mitigate inter-area power frequency oscillations. A large-scale power system is decomposed into a network of passivity-short subsystems whose nonlinear interconnections have a state-dependent affine form, and by utilizing the passivity shortage framework, a two-level design procedure is developed. At the lower level, any generator control can be viewed as one that makes the generator passivity-short and L2 stable, and the stability impact of the lower-level control on the overall system can be characterized in terms of two parameters. While the system is nonlinear, the impact parameters can be optimized by solving a data-driven matrix inequality (DMI), and the high-level wide-area control is then designed by solving another Lyapunov matrix inequality in terms of the design parameters. The proposed methodology makes the design modular, and the resulting control is adaptive to operating conditions of the power system. Standard test systems are used to illustrate the proposed design, including DMI and the wide-area control, and simulation results demonstrate its effectiveness in damping out inter-area oscillations.

“…However, these works do not focus on the impact and technical challenges that the widespread integration of solar PV systems poses on the interconnected power system. Similarly, various control strategies have been reported in [14][15][16][17][18], for optimal control of synchronous machine-based power systems.…”

This paper proposes a disturbance‐observer‐based control (DOBC) scheme for frequency and voltage regulation in modern power systems with high renewable energy sources (RES) penetration. The proposed approach acts as a feed‐forward control that improves the dynamic performance of the conventional proportional‐integral‐derivative (PID) controller. The proposed voltage and frequency control has been validated through hardware‐in‐loop (HIL) implementation on OPAL‐RT, and testing on laboratory‐scale experimental test setup. The robustness of the proposed control scheme has been validated through simulations under worst‐case and stochastic uncertainties to mitigate real‐time variability in RES output and load. Real‐time simulation results depict superior performance of the proposed control strategy in comparison to several well‐established techniques under practical operating conditions, in the presence of communication delay and white noise. To validate the proposed control on laboratory‐scale experimental setup, the digital twin of the physical plant transfer function has been designed. Results reveal that the proposed DOBC control scheme drastically improves the system performance without rendering much computational burden under practical operation scenarios.

“…However, the effectiveness in damping the inter-area modes is limited , because the inter-area modes are not as highly controllable and observable in the generator's local signal as the local modes. Meanwhile, the Governor-side PSS with local signals are also theoretically developed and discussed [5][6][7][8]. However, the performance of the governor-side PSSs with local signals are also limit, especially for the inter-area modes, since inter-area modes are mainly influenced by the global states, while the local Governor-side PSSs also use the local signal as the control input, which is similar to LPSSs.…”

Low frequency oscillation (LFO) is harmful to power system security and stability. The traditional solutions for LFO are the power system stabilizer (PSS) with local or global signal implemented on the excitations. This paper explores the global governor-side damping controllers for LFO, i.e., controller with input from the wide area measurement system (WAMS). Design strategy of global governor-side damping controller with remote signal from WAMS is proposed, based on the partial state feedback theory. Simulation results in a 4-generator-2-area power system show the effectiveness of the proposed global governor-side damping controller.
