Droop control is broadly used in source paralleling and distributed dc systems. While the dc droop resistance guarantees static load sharing, the output impedance determines the dynamic performance and is important in stability analysis. In this paper, a general small signal model is established to derive the output impedance of a droop-controlled power source. Using buck converter as an example,...
In this paper, an enhanced power sharing strategy employing adaptive virtual impedances for Q-ω and P-V droop-based islanded microgrids (MGs) is proposed. The proposed scheme improves the performance of dynamic response and system stability while accurate power sharing is obtained. The low-bandwidth communication is utilized to send the power commands. The adaptive virtual impedances consist of a...
In this paper, thorough analysis is carried out on a microgrid system with a constant power load. Constant power loads make the system to be unstable due to their negative impedance characteristics and this is proved for the microgrid system by deriving the small signal state space model for the system and then observing the location of the system poles. Subsequently, a sensitivity analysis is carried...
