Decentralized control methods of microgrids with RES for the improvement of steady-state and transient operation

Abstract

The operation of modern distribution grids has changed due to the high integration ofDistributed Energy Sources (DER). For this reason, quantities of DERs, energy storagesystems (ESS) and loads form subsystems, called microgrids. The microgrids can operateboth grid-connected and isolated in island mode. As the majority of DERs are connectedto microgrid through DC/AC or AC/DC/AC converters, the operation of the microgrid canbe controlled by developing the proper control strategies for these converters.The operation of the microgrid can be divided in several control levels. The primarylevel aims mainly in the steady state operation. In order to avoid communicationinterconnections among the DERs or among the DERs and a central controller, the droopcontrol methodology is mainly adopted. According to this method, each DER injects activeand reactive power, forming the frequency and the voltage of each node, with respect topermissible limits. This operation emulates the parallel operation of ...
