New adaptive controller in a two area HVAC/HVDC power system

In this paper, a system which includes two ties (AC and DC), interconnecting two large AC networks, is studied. The system includes DC control interacting with the conventional AC area controls. In this regard, optimal exploitation of classical controllers has been a controversial issue in reputable journals. In this article, the stability of the network in each of the areas is controlled by a new control method that is a Model Reference Adaptive Control method (MRAC) based on the combination of Linear Quadratic Regulator (LQR) control and the Genetic Algorithm (GA) is introduced. Genetic algorithm is employed to find the best values for gains of the controller in a very short time. The simulation results show an improvement in the dynamic performance of the test AC/DC system.
