A Novel Optimal Control Method for Islanded Microgrids Based on Droop Control Using the ICA-GA Algorithm
Microgrids are small scale power systems with local resources for generation; consumption and storage, that can operate connected to the main grid or islanded. For the islanding operation of microgrids, two important tasks are to share the load demand and maintain the voltage and frequency stabilities. In order to achieve this goal, a hierarchical control structure can be employed. This researc...
متن کاملOptimal Droop Control for Voltage Source Converters in Islanded Microgrids
A new procedure for the design of the droop control for voltage source converters (VSC) in islanded microgrid is presented. The droop control is commonly used to achieve the power balance in power system. It consists in a simple proportional control and the selection of its gains are commonly based only on power balance criteria. However, some values of the gains may cause poor damped responses...
متن کاملAdvanced Droop Control in Islanded Microgrids Using Dynamic Phasor Models
A dynamic phasor model for lowand medium-voltage distribution grids is presented. This model accurately represents the transient dynamics of this type of grid, and its low order makes it well suited for control design. A novel fixed-structure, robust control design method based on convex optimization is then used to design a decentralized low-order controller that shows a significantly improved...
متن کاملAn Enhanced Droop Control Scheme for Islanded Microgrids
Due to the line impedance impact on islanded low-voltage microgrids, traditional droop control cannot guarantee the proper power sharing between distributed generation (DG) units. In the meanwhile, droop control would cause voltage and frequency deviation, which will influence the power quality of customers. This paper proposed an enhanced droop control scheme with autonomous frequency restorat...
متن کاملnew control method of islanded microgrid system: a ga & ica based optimization approach
microgrids are small-scale, low voltage (lv) power networks which employ renewable distribution energy resources (ders) with power electronic interfaces (peis). microgrids as single controlled units and active distribution networks require flexible control systems to ensure reliable and secure operation in different modes. these various operations of microgrid cause variations in voltage and fr...
