POWER SYSTEM VOLTAGE CONTROL BASED ON LEARNING HUMORAL IMMUNE RESPONSE

At first, the basic process of the humoral immune response is introduced briefly. Then, the basic structure of the humoral immune voltage controller is proposed. Simulated the process of humoral immune response clear the antigen, a P-type and reinforcement learning algorithm for training the parameters of the controllers is presented. In this paper, the control ability of STATCOMs is demonstrated. The example system is the New England System installed with two STATCOMs. The parameters of the humoral immune voltage controllers are designed by the proposed learning algorithm. The learning process demonstrated the algorithm has better convergence and high robustness. And the digital simulation demonstrated the control strategy is effective. Simulation results make sure that the proposed humoral immune voltage control can not only keep the voltage at the controller's busbar to a setting reference value at the normal operation mode, but also minimize or eliminate voltage violations at its adjacent busbars in power system contingencies.
