Application of cell immune response modelling to power system voltage control by STATCOM

Just like neural networks and genetic systems, immune systems are sophisticated, biologically motivated information processing systems of human beings. A mathematical model for the cell immune response is proposed, aiming at an application in power system voltage control. This application is based on the idea that the violations of a power system voltage profile are antigens to the healthy operation of a power system, and they can be killed through the cell immune response implemented by voltage control. An example of STATCOM control via the cell immune response is demonstrated in the New England 10-machine 39-node power system. The STATCOM control based on the cell immune response can not only maintain the voltage level at the STATCOM busbar at the setting reference value for normal operation mode, but also eliminate voltage violations at the STATCOM's adjacent busbars in system contingencies.
