The frequency and tie-line power in a system varies as the load changes. Therefore in order to damp the frequency, Load Frequency Control (LFC) is used. The function of the LFC is to minimizes the transient deviation and to make the steady state change in frequency, zero. This paper presents a Load frequency control (LFC) of Doubly Fed Induction Generator (DFIG) based two area system using Thyristor Controlled Phase Shifter (TCPS), Static Synchronous Series Compensator (SSSC) and Superconducting Magnetic Energy storage (SMES). Flexible AC Transmission Systems (FACTS) devices and SMES are used to damp out the frequency oscillations effectively in a power system. In order to maintain the system frequency at nominal value and the oscillations to settle down quickly a fast acting controller is desirable. In this paper a MATLAB based PID controller has been proposed in order to minimize the damping oscillation of the two-area interconnected power system. The results obtained with various combinations are presented and the results were encouraging.

Load frequency control (LFC) in interconnected power system of small distribution generation (DG) for reliability in distribution system. The main objective is to performance evaluation load frequency control of hybrid for interconnected two-area power systems. The simulation consist of solar farm 10 MW and gasifier plant 300 kW two-area in tie line. This impact LFC can be address as a problem on how to effectively utilize the total tie-line power flow at small DG. To performance evaluation and improve that defect of LFC, the power flow of two-areas LFC system have been carefully studied, such that, the power flow and power stability is partially LFC of small DG of hybrid for interconnected two-areas power systems. Namely, the controller and structural properties of the multi-areas LFC system are similar to the properties of hybrid for interconnected two-area LFC system. Inspired by the above properties, the controller that is propose to design some proportional-integral-derivative (PID) control laws for the two-areas LFC system successfully works out the aforementioned problem. The power system of renewable of solar farm and gasifier plant in interconnected distribution power system of area in tie – line have simulation parameter by PID controller. Simulation results showed that 3 types of the controller have deviation frequency about 0.025 Hz when tie-line load changed 1 MW and large disturbance respectively. From interconnected power system the steady state time respond is 5.2 seconds for non-controller system, 4.3 seconds for automatic voltage regulator (AVR) and 1.4 seconds for under controlled system at 0.01 per unit (p.u.) with PID controller. Therefore, the PID control has the better efficiency non-controller 28 % and AVR 15 %. The result of simulation in research to be interconnected distribution power system substation of area in tie - line control for little generate storage for grid connected at better efficiency and optimization of renewable for hybrid. It can be conclude that this study can use for applying to the distribution power system to increase efficiency and power system stability of area in tie – line.
