In this paper, an integrated and modular control design is developed for distributed energy resources (DERs) to stabilize power systems and minimize effects of load variations and intermittent generation. Traditionally, the droop control of each generator (or virtual power plant) works as a local feedback loop to track frequency during load disturbance, whereas automatic generation control (AGC) calculates...
In this paper, the impact of integration of FACTS devices viz. TCPS and TCSC on Automatic Generation Control (AGC) of a two area thermal-thermal deregulated power system have been studied in order to enhance the performance of responses such as frequency deviation and oscillation damping, deviation of tie line power between the areas and power generated by GENCOs. The comparison of results between...
The penetration level of distributed generation (DG) grows rapidly bringing more frequency fluctuation nowadays. Besides, the power system grows in size day by day; the assumption that the frequencies are the same across the grid is no longer valid. These all bring out problems to the frequency control mechanism currently used. The recently proposed rotor angle control strategy may solve these problems...
In this work applications of Flexible AC Transmission System (FACTS) devices have been used in Automatic Generation Control (AGC) to improve the performance such as oscillation damping of transient response of power system in deregulated environment. The oscillations in frequency, tie power, generated power etc. are compared with conventional integral controller and FACTS devices. The responses improve...
