With the decrease in system inertia, frequency security becomes an issue for power systems around world. Energy storage (ESS), due to their excellent ramping capabilities, are considered as a natural choice improvement of response following major contingencies. In this paper, we propose new strategy energy – <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1...

In this article, the sliding mode control of frequency load control of power systems is studied. The study areaconsists of a system of water and heat. First, a mathematical model of the proposed system disturbances ismade and then sliding control mode for frequency load control is provided. By the system simulation andsliding mode control, it can be shown that the damping of oscillations is wel...

An electronic method of control that has been known since the early thirties is that of the phase-lock-loop technique. In this method the phase angle of a periodic signal whose frequency corresponds to the value of the quantity to be controlled is continuously compared with the phase angle of an applied signal whose frequency represents the specified value. A change in the phase difference betw...

In the proposed paper, we have presented the need for Load Frequency Control (LFC) of an interconnected multi-area power to minimize the transient deviations in area frequency and tie-line power interchange and to ensure their steady state errors are zeros. In this paper, the Load Frequency Control achieved by implementation of one of the following conventional controller strategies: Proportion...

This study proposes a combination of a fuzzy sliding mode controller (FSMC) with integral-proportion-Derivative switching surface based superconducting magnetic energy storage (SMES) and PID tuned by a multi-objective optimization algorithm to solve the load frequency control in power systems. The goal of design is to improve the dynamic response of power systems after load demand changes. In t...

Power systems are composed of power units that are constantly connected to each other and the electric power flux is constantly moving between them. All systems must be implemented in such a way that not only under normal conditions but also unwanted inputs or disturbances, are applied. It also remains stable or returns to a stable name at the earliest possible time. The fundamental factors...
