This paper utilizes the application of Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) techniques to find the most appropriate locations of Unified Power Flow Controller (UPFC) with optimum cost of generation for loadability limit and minimum active power loss, while satisfying the power system constraints. Two objective functions are taken as the indexes of the system performance:...

This paper proposes a novel technique for representing system security in the operations of decentralized electricity markets, with special emphasis on voltage stability. An Interior Point Method is used to solve the Optimal Power Flow problem with a multi-objective function for maximizing both social benefit and the distance to maximum loading conditions. A 6-bus system with both supply and de...

1 Abstract — This paper presents a potential algorithm for continuation power flow method in voltage stability assessment. Modified continuation power flow method termed as MCBF was developed which solved the solution of bifurcation point at the Q-V curve. The solvability of power flow at the bifurcation point beyond the maximum loadability point of a system was achieved through the implementat...

The objective of this paper is to investigate the thermal behaviour and loadability characteristic a yokeless segmented armature axial-flux permanent-magnet (YASA-AFPM) generator, which uses an improved 3-D coupled electromagnetic-thermal approach. Firstly, 1-kW YASA-AFPM generator modelled analysed by using proposed approach; transient steady-state temperatures different parts are determined. ...

With Denmark dedicated to maintaining its leading position in the integration of massive shares wind energy, construction new offshore energy islands has been recently approved by Danish government. These will be zero-inertia systems, meaning that no synchronous generation installed island and power imbalances shared only among converters. To this end, paper proposes a methodology calculate upd...

Research effort has been given to find the optimal location and initial settings of Thyristor-Controlled Series Capacitor (TCSC) using Mixed-Integer Linear Programming (MILP). As a useful tool for combinatorial optimisation over integer and continuous variables, mixed-integer programming approach can provides robust performance as well as high computation efficiency when solving complex optimal...

This paper proposes a new index to determine the static voltage stability of the load buses in a power network for certain operating conditions and hence identifies load buses which are close to voltage collapse. The proposed index is formulated from the quadratic equation derived from a twobus network and is computed using the apparent power and the line impedance. The proposed index shows how...
