Multi-index nonlinear coordinated control for Battery Energy Storage System and generator excitation

Abstract

The power system model with Battery Energy Storage System (BESS) compensation devices which integrate classic third-order generator model and BESS model is deducted and established in this paper. Using multi-index nonlinear control design method, BESS and generator excitation are designed by coordinate control scheme for this model above. The controller proposed by this paper is good at improving the dynamic characteristics of state variables, so as to enhance the stable operation capacity of the system. Simulation demonstrates the effectiveness and practicality of the controller for one-machine infinite power system.
