Thesis on automatic generation control

The supplementary control adjusts load reference set points of the generators for control action. This thesis mainly contributes in the area of Automatic Generation Control AGC of single area and multi area power systems in regulated as well as deregulated restructured environments. To improve the performance of the AGC and to overcome the limitations of conventional integral controller the use of intelligent systems are required. Attempt has also been made to improve the performances using fuzzy controllers. The controller generally used as supplementary controller is of integral or proportional integral type but as these controllers are considerably slow and take more computing time in estimation of suitable parameters hence other types of controllers using artificial intelligence techniques are being used to improve AGC performance. A supplementary control action is used to keep the deviations in frequency and tie line flow to zero. At present, slow response to AGC load demand is a serious problem existing in thermal power units taking part in AGC, which makes the control performance of power system AGC poor. Availability of frequency based tariff scheme is employed. And at the last market structure is considered. Demand can be managed by managing the tariff. To develop AGC model considering generating rate constraints. Through adopting the connection logic of CCS with AGC, the pre-add coal function can be realized in AGC mode, which assured the rapid response to AGC load demand of the power unit, and this viewpoint has been fully proved by the trend curves of AGC adjusting test of the two units.

Steady state values of frequency, tie line power interchange and power generated by different GENCOs have also been examined for the systems under study. The approach to this solution will include research of the approaches and application of real world values in these approaches.

Thesis on automatic generation control

The research in this thesis is aimed to meet these gaps and extend the work which have been done till date in the area ofAGC in traditional as well as restructured environments.

In a restructured power system, AGC objective remains the same as in traditional power system but its application in the system differs. This thesis mainly contributes in the area of Automatic Generation Control AGC of single area and multi area power systems in regulated as well as deregulated restructured environments.

Availability of frequency based tariff scheme is employed. The use of HVDC link in parallel with ac tie line as interconnection between two areas has been applied in restructured power system with controller as optimal controller which gives improved performance as compared to the case without HVDC link in the same system.

To develop AGC model based on market structure. Different FACTS devices have been applied in power system models to damp out transient response oscillations quickly. These gave encouraging results and further improvement was achieved when fuzzy controllers were replaced by the integral controllers. An attempt has been made to compare the IV performances of these controllers in terms of peak deviations and time taken to damp out oscillations. The controller generally used as supplementary controller is of integral or proportional integral type but as these controllers are considerably slow and take more computing time in estimation of suitable parameters hence other types of controllers using artificial intelligence techniques are being used to improve AGC performance. In the restructured power system, different controllers have been applied for frequency and tie-line power regulation in the new environment. To develop model for coupled automatic generation and voltage control. This thesis mainly contributes in the area of Automatic Generation Control AGC of single area and multi area power systems in regulated as well as deregulated restructured environments. It is expected that research will add the world of AGC struction on demand side management.

To improve the performance of the AGC and to overcome the limitations of conventional integral controller the use of intelligent systems are required. The unit one and unit two of are all boiler, its boiler-turbine coordinated control system CCS is based on incremental state observer combined with conventional PID control, and the connection logic of CCS with AGC adopted the scheme shown in this paper.

To improve the performance of the AGC and to overcome the limitations of conventional integral controller the use of intelligent systems are required. Artificial Intelligence techniques like Fuzzy Logic, Particle Swarm Optimization and Genetic algorithms have been applied for this purpose. To develop AGC model based on market structure. The approach to this solution will include research of the approaches and application of real world values in these approaches.

In the restructured power system, different controllers have been applied for frequency and tie-line power regulation in the new environment. Therefore to make system in normal State need to study management in generation as well as demand.
