This paper presents the stability-improvement results of a synchronous generator (SG)-based one-machine infinite-bus (OMIB) system with a hybrid doubly-fed induction generator (DFIG)-based and permanent-magnet synchronous generator (PMSG)-based offshore wind farm (OWF) using a static synchronous compensator (STATCOM). The operating performance of the studied PMSG-based OWF is simulated by an eq...

This article discusses the development of a Power System Stabilizer (PSS) utilizing Virus Particle Swarm Optimization Algorithm (VEPSO) to enhance power system stability. PSS is commonly used in industry suppress oscillations. The proposed algorithm was implemented on Single Machine Infinite Bus (SMIB) system, and controller coefficients were optimized using VEPSO. simulated under specific dist...

This paper presents a methodology for implementing artificial neural network (ANN) observers in estimating and tracking synchronous generator parameters from time-domain online disturbance measurements. Data for training the neural network observers are obtained through off-line simulations of a synchronous generator operating in a one-machine-infinite-bus environment. Nominal values of paramet...

The ongoing decarbonization, and the rapid increase in renewable penetration electric grid, will demand enhanced flexible operational schemes of conventional hydropower plants. This paper explores a grid-connected plant’s best-efficiency operating conditions when meeting energy transition. Power loss models combined with various voltage control methods are investigated for achieving optimal ope...

The low voltage ride-through (LVRT) capability of the doubly-fed induction generator (DFIG) significantly impacts upon the integration of wind power into the power grid. This paper develops a novel comprehensive control strategy to enhance the LVRT and reactive power support capacities of the DFIG by installing the energy storage system (ESS). The ESS is connected to the DC-link capacitor of th...

In this paper, a novel Harmony Search algorithm (HSA) based approach for robust and optimal design of PID controller connected to power system stabilizer (PSS) is proposed for damping low frequency power oscillations of a single machine infinite bus bar (SMIB) power system. This paper attempts to optimize the three parameters (Kp, Ki, Kd) of PID-PSS via a music-based metaheuristic optimization ...

This paper uses the Particle Swarm Optimization (PSO) technique to investigate the damping control function of an Interline Power Flow Controller (IPFC) installed in a power system. For this purpose, the linearized Herffron-Phillips model of a Single-Machine Infinite Bus (SMIB) system is established and a performance index which is defined based on the system dynamics is applied as an objective...
