DC microgrid contains a large number of tightly regulated closed-loop converters, which performance for the constant power loads and may cause stability problem of bus voltage when used as a load since they trend to draw constant power. In order to improve the stability of DC microgrid, this paper proposes a method for stabilization the DC microgrid based on the state feedback. e. In this study, the small disturbance linearised state equation of a DC-power grid with constant power load is derived to estimate the damping characteristics of DC voltage. To enhance the transient voltage stability, a novel DC- voltage damping control method is proposed, where both DC voltage and DC current are used as state feedback variables.

“…Nowadays, because simple control, higher efficiency, and higher levels of reliability compared with AC microgrids, DC microgrids have gained significant popularity. 1 The dynamics of power production equipment in such microgrids have lower levels of inertia. 2 Thus, in order to make stable operation of microgrids, rapid regulation of loads using power electronics converters 3 has a vital importance.…”

Summary For the stable operation of a grid, the load regulation in the network with distributed generation resources and loads is very important. In this article, game theory (the Nash and Stackelberg equilibriums and their combination) is applied to adjust the loads and voltages of the system. The purpose method is implemented on a 9‐bus microgrid and the optimal solutions for the Nash and Stackelberg and combining equilibriums are determined and compared. The results indicate that the introduced method can create a competitive environment with consideration of the priorities of the loads for power and voltage regulations.
