Decentralized power control management with series transformerless H-bridge inverter in low-voltage smart microgrid based P/V droop control

A performance comparison of series power flow control structures in a smart microgrid

“…A controlled voltage source is used to model the microgrid and the load included in the microgrid is presumed to be resistive. The system data and parameters values are stated in [13]. The behavior of the developed series power flow controller is investigated in different operation modes (capacitive and inductive) for each type of the control methods.…”

“…ISSN: 2088-8694  the single phase transformerless H-bridge inverters [13], and the smart transformer [14]. However, the cost, size and complexity, operationality of the control strategy and its appropriacy on the intended controller are the main challenges encountered in power flow control studies.…”

“…An active power point of common coupling (PCC) control method has been introduced in [14] by installing a smart transformer at the interface point between the main network and the microgrid to control the active power exchange between both networks using voltage-based droop control concept. Two novel control strategies applied on a transformerless H-bridge inverter connecting the main grid and the microgrid have been implemented for power flow control between both of them, where their feasibility is verified during different operation modes [13]. A new control methodology has been evolved to run the H-bridge inverter as a power flow controller between the main network and the microgrid [22].…”
