The modern electric grid is one the most complex man-made control systems. Automatic generation control plays an important role in power system operation to maintain the frequency within an acceptable range and to properly respond to load changes under normal conditions. Many publications have been made in the area of Load frequency control (LFC) of interconnected power systems. Load frequency control is necessary to develop better control in order to achieve less effect on the frequency and tie line power deviations after a load perturbation. However, number of control strategies has been employed in the design of load frequency controllers in order to achieve a better dynamic response and the exact choice of the LFC controller in a particular case requires sufficient expertise because each controller has its own merits and demerits. Due to this, an appropriate review of load frequency control (LFC) mechanism is essential and a few attempts have been made in this concern. This paper presents a detailed survey on load frequency control (LFC) mechanism. In this paper detailed analysis of various control methodologies based on classical control, robust and self-tuning control and various soft computing control techniques are discussed. Finally, the investigations on incorporating fast acting energy storage devices such as Battery energy storage system (BESS), superconducting magnetic energy storage (SMES), Redox flow batteries (RFB) and Flexible AC transmission systems (FACTS) devices for mitigating the LFC problems in a deregulated power system are also addressed.

This paper is treating the problem of identifying stability reserves and finding out the best solutions to improve available security margins in order to be at a safe "distance" from a blackout in the analyzed power system. The issue consists in the computation of the stability limits for a power system either with or without using FACTS devices in order to highlight the gain in power system stability and control by using these devices.The key aspects of the well known approaches related to the steady-state stability limits (SSSL) computation is reviewed and an algorithm for SSSL identification, developed by the authors in order to be fitted for power systems planning and operation is also described. A methodology to choose between different locations for a FACTS device in order to increase the security margins of the analyzed power system is going to be proposed. The paper is focusing on the aspects of preventing blackouts by finding out a methodology to establish the need of FACTS devices in a power system. The technical aspects treated here consist in assessing the stability reserves for a power system or for a specific constrained area in a power system (with and without using the FACTS devices) beyond which a blackout might appear.Index Terms-security margins, voltage stability limit, steadystate stability, time domain analysis, stability limits, FACTS devices.
