“…SC is equivalent to a capacitive or an inductive reactance connected in series with the line. Voltage Source Inverter (VSI) is the main part of a SC that is supplied DC from a storage capacitor [7]. Without external DC-link, the series injected voltage has two components: the main component is in quadrature with the line current and emulates capacitive or an inductive reactance in series with the line.…”

Parallel transmission lines can be utilised for a flow power from a surplus generation area to a load center in a meshed power grid. The distribution current flow in these parallel transmission lines depends on impedance value of the line. The lowest value of impedance will reach the maximum capacity of transmission earlier than other parallel transmission paths and thus determines the maximum transmittable capacity of power, while the other parallel paths are not loaded to maximum capacity. In this paper, a modeling and simulation of parallel transmission lines is presented with series compensator SC for regulating the flow power. The adaptive fuzzy logic control scheme is proposed, Takagi-Sugeno rules type are trained by using off-line in this controller. The results of this study show the ability of the static compensator SC to regulate the power flow in the controlled transmission line between 50 and 100 percent of the rated power flow.

“…Nowadays, modern electrical power systems are operated close to their stability limits. This is due to factors such as continuous growth in load demand, economic constraints, new policy, deregulations in some countries, and environmental constraints in the transmission lines . As a consequence, voltage instability is likely to occur.…”

Summary Voltage stability has of recent been a subject of growing concern to power system utilities. In this paper, 2 techniques, one based on topological structure of power networks and the other on the conventional power flow solution, are proposed for voltage stability analysis. The network structural characteristics theory participation factor proposed is formulated to identify the weak bus of the system. The voltage stability enhancement is achieved through the incorporation of power electronic–based thyristor‐controlled series compensator device. This is done by modifying the admittance matrix and network structural characteristics theory participation factor formulated to incorporate the effect of variable reactance of thyristor‐controlled series compensator device. The second suggested approach based on power flow is also investigated. The results of both techniques are compared with the conventional approaches. The results of simulations obtained show that voltage stability enhancement can significantly be achieved from the network structural point of view, as it saves time and reduces system computational burden.

Abstract. This paper describes an approach powers flow control for an electrical network connected with a wind farm. In this work the powers flow control are performed through a Static Synchronous Series Compensator (SSSC) which is one of among Flexible AC Transmission System devices (FACTS). The wind farm is based on doubly-fed induction generators (DFIG). The simulation results show the effectiveness of the proposed approach making better the damping of power oscillations caused by the wind farm, ensuring the minimizing system transmission losses while providing a best voltage level. The simulations are done in MATLAB/ Simulink/ SimPowerSystems environment.
