Abstract—The power system frequency falls when disturbance such as rapid increase of system load or loss of a generating unit occurs in power systems. Especially, increase in the number of renewable generating units has a bad influence on the power system because of loss of generating unit depending on the circumstance. Conventional technologies use frequency droop control battery output for th...

With conventional droop control, the relationship between voltage and reactive power is not purely linear because of filter reactance. This paper focuses on theoretical analysis to account for this characteristic presents a precise flow method control. The proposed universal, which can handle only but also other control strategies, such as robust constant voltage–frequency It frequency-dependen...

This paper proposes a decentralized control technique to minimize the total operation cost of a DC microgrid in both grid-connected and islanded modes. In this study, a cost-based droop control scheme based on the hourly bids of all participant distributed generators (DGs) and the hourly energy price of the utility is presented. An economic power sharing technique among various types of DG unit...
