Interconnected power systems are critically vulnerable to instability due to the disturbances in any one portion of the system. Even low-frequency oscillations and small disturbances may lead to an outage of the system. Properly tuned Power System Stabilizer (PSS) is an effective tool for the suppression of these oscillations. This paper proposes a novel approach to tune proportional-integral (PI),...
The Effect of increasing penetration of full converter controlled-based generators (CCBGs) in a large scale power system is evaluated by using MATLAB program based on small signal stability analysis. The power system has been subjected for two types of tests, the first test has been implemented by disturbing the system through applying 3-phase fault at the infinite bus system, and the second one by...
In this paper, different selection, crossover including deferential evolution and mutation techniques are considered for optimizing the electrical power loss in real hydrocarbon industrial plant using genetic algorithm (GA). The subject plant electrical system consists of 275 buses, two gas turbine generators, two steam turbine generators, large synchronous motors, and other rotational and static...
This paper presents a study for demonstrating the capability of photovoltaic systems (PV System) in enhancing the damping of the inter-area oscillations in a smart grid network. In this context, investigations are conducted on a single-machine infinite bus (SMIB) system. PV-based stabilizer are designed for enhancing power system dynamic stability. The damping action is achieved through the independent...
This paper presents a study of tuning the existing power system stabilizers (PSSs) of the Saudi Electricity Company (SEC) power system and its effect on increasing the power transfer limit of the interconnection between Eastern Operating Area (SECE-OA) and Central Operating Area (SEC-COA). This work is also investigating the optimal location of installing additional power system stabilizers (PSSs)...
This paper presents a multi-objective evolutionary algorithm for environmental\economic power dispatch (EEPD) problem. The multi-objective evolutionary algorithm based on differential evolution (MODE). In this algorithm, the differential evolution (DE) concept for the single objective optimization is extended to multi-objective optimization. The EEPD problem is formulated as a true nonlinear constrained...
In this paper, three voltage stability indices (VSIs) have been assessed. The voltage stability problem has been formulated as an optimization problem. Genetic algorithm (GA) has been employed to solve this optimization problem. Wale & Hale 6 bus system was used in this paper study.
