Abstract:

Most distributed control works only concern the voltage control of distributed generators (DGs) and fail to consider the voltage demands of other loads. These loads, such as sensitive industrial loads, may have certain voltage operation demands. This study develops a multi-bus-based distributed control method of microgrids to achieve voltage control among the points of DGs and loads. Different from the common single-leader-based distributed control, the proposed method transforms the cooperative bus voltage control of DGs and loads into a multi-leader-based distributed control problem. Thus, not only the DGs but also the voltages of load points can be converged into a given range. Besides, a nonlinear control theory is introduced into the distributed algorithm to improve the convergence rate. A Lyapunov candidate is employed to verify the stability, and the Matlab/Simulink simulations are conducted to test the performance of our method.
