Deregulated AGC scheme using dynamic programming controller

In this paper an optimal controller based on Action Dependent Heuristic Dynamic Programming (ADHDP) approach has been proposed for multi area Automatic Generation Control (AGC) scheme. A competitive environment has been considered in the interconnected power system. Conventional AGC model has been modified to include bilateral transactions taking place in the energy market. To implement the ADHDP approach discrete model of modified AGC scheme has been utilized. ADHDP is a powerful technique of Approximate Dynamic Programming, used for providing optimal solution by minimizing the given objective function. The proposed approach has been tested on two area AGC scheme for different cases. The results have been compared with the discrete full state feedback controller.
