چکیده
Aiming at the bus voltage fluctuation caused by nonlinearity, limited change and uncertain factors such as deviation, load system parameter traditional droop control in DC microgrid, a precise scheme considering constraints is proposed. Firstly, parabolic used to replace linear improve accuracy of power distribution. On this basis, controller based on barrier Lyapunov function designed precisely reach expected value. The adopts backstepping method deal with nonlinear problems; design meet condition constraints; RBF neural network eliminate uncertainty disturbance suppression ability system. simulation results show that can ensure stability when changes parameters change, its performance better than PI control. It achieve high-precision distribution state limited. verify strategy reduce drop stability.

The microgrid (MG) concept is attracting considerable attention as a solution to energy deficiencies, especially in remote areas, but the intermittent nature of renewable sources and varying loads cause many control problems and thereby affect the quality of power within a microgrid operating in standalone mode. This might cause large frequency and voltage deviations in the system due to unpred...
متن کاملVoltage Control and Load Sharing in a DC Islanded Microgrid Based on Disturbance Observer
Increasing DC loads along with DC nature of distributed energy resources (DERs) raises interest to DC microgrids. Conventional droop/non-droop power-sharing in microgrids suffers from load dependent voltage deviation, slow transient response, and requires the parameters of the loads, system and DERs connection status. In this paper, a new nonlinear decentralized back-stepping control strategy f...
