Static synchronous series compensator (SSSC) belongs to the facts family. It controls the flow of power in transmission line. The SSSC is a voltage source inverter connected in series with the transmission line and injects the voltage in quadrature with line current. Demand of power is growing day after day. Installation of new transmission lines is difficult because of environmental factors. The power flow capacity of existing transmission line has to be increased which is done by using compensation devices. The main reason behind poor performance of transmission system is the power flow capacity of existing transmission line under dynamic situations subjected to disturbances. FACTS technology opens new opportunities for controlling power and increases the usable capacity. It enhances corresponding power to flow through such lines under normal and contingency conditions. Recently new advancement in FACTS technology has introduced devices for reactive power compensation. In this paper, a case study is discussed and test system is simulated in MATLAB/Simulink under normal conditions and also under fault conditions to improve the transient stability of the system. A 132kv transmission line coming from Kohat grid station to tall grid station has been selected as a test system which is suspected to overloaded conditions due to which voltage stability could not be maintained especially during the months of June, July and August. Static synchronous series compensator (SSSC) is installed near the Kohat bus. The results of current, voltage, active power and reactive power have been analysed with and without SSSC in the test system. Results shown that the stability of power system, voltage profile and power flow capability enhances by using SSSC. Also by using SSSC the oscillations were damped very quickly as compared to the circuit without using SSSC and the stability is maintained.

“…However, if no appropri-ate control action is taken, the undamped oscillations can endanger the operation of the network. Networks which contain weakly coupled transmission links operating under heavy load transfer conditions are particularly prone to this type of problem [9][10][11][12]. In this regard, the proposed PV system to be considered in this paper is intended for providing the ability to enhance network dynamic stability.…”

Due to the increasing amount of photovoltaic (PV)-based power generation being connected to power systems, issues pertaining to the integration of the PV-based generators have attracted intense attention. In this connection, the design of a PV-based stabilizer for enhancing power system dynamic stability is examined. The damping action is achieved through the independent control of real power flow from the stabilizer and voltage at the point of common coupling between the stabilizer and grid system. The stabilizer system is designed based on classical frequency response technique. Robustness of the proposed control strategy in enhancing network dynamic stability is demonstrated through computer simulation

“…Instability problems resulting from inter-area oscillations are caused by insufficient system damping and relatively weak tie-line connectors. If no appropriate action takes place, then this oscillation may endanger the power network [25][26][27][28][29].…”

Solar energy is one of the emerging forms of renewable energy, and has been proved to be a potential source for generation of electricity. However, the rise in number of photovoltaic (PV) generators presents issues for electric power utilities. Thus, integration of a PV system to the grid, is an important area of research. Out of the various issues faced by the utilities, one of the main issues is related to power system stability. The objective of this thesis is to achieve stability for a grid-connected PV system with the proposed new power system stabilizer (PSS). Stability is attained by conducting small signal analysis and time domain analysis on the investigated PV system. First, time domain analysis on detailed and average PV system models without PSS is performed. Second, small signal stability analysis on average PV system model with and without PSS is performed. It is observed that the damping effect and the dynamic stability of the investigated PV system are achieved, with the help of the proposed new PSS Conclusions and Future Work……………………………………….…………....88
