Peer-to-peer Energy Transaction in Microgrids with Power Electronics Enabled Angle Droop Control Conference Paper uri icon

abstract

  • © 2018 IEEE. In this paper, a modified Angle Droop Control (ADC) scheme is presented with added flexibility for accurate peer-to-peer Transactive Energy (TE) control in an interconnected microgrid system. The proposed scheme enables TE (i.e., energy transfer on demand) between two or more microgrids with simultaneous guaranteed stable operation due to overlaid ADC. To enable such a scheme, the concept of a power router (PR) for power flow control is introduced. The PR is realized by augmenting a fractionally rated transformer with AC-AC converter blocks (also fractionally rated). This leads to a topology which is named as Power Electronics Transformer with Dynamic Voltage and Angle Droop Control (PET-DVADC). The interface of the proposed topology resides at distribution voltage level of the micro-grid interface point before the step-up transformer. Extensive simulations on a five interconnected microgrid architecture are presented. Energy transactions between two and three microgrid examples are discussed with the proposed PET-DVADC control.
