Abstract:

This paper suggests a new control method to modify the virtual impedance performance in unbalanced conditions. The proposed method compensates the voltage drop that occurred due to the virtual impedance and adjusts the voltage of the point of common coupling at a desirable level. To compensate the voltage drop, the reference voltage in the droop control varies according to the proposed algorithm. Moreover, a modified decoupled double synchronous reference frame is introduced to achieve appropriate active and reactive power sharing and voltage balancing, simultaneously. Finally, the simulation results in MATLAB/Simulink are provided to validate the accuracy and effectiveness of the proposed approach.

A Repetitive Control- based Approach for Power Sharing among Boost Converters in DC Microgrids

In this paper a repetitive control (RC) approach to improve current sharing between parallel-connected boost converters in DC microgrids is presented. The impact of changes in line impedance on current sharing is investigated. A repetitive controller is designed and connected in series with current controller of the boost converters to control the switching signals such that by regulating of th...

Suggested New Voltage and Frequency Control Framework for Autonomous Operation of Microgrids

Decentralized control strategies are popular candidates in microgrids control because of their reliability and performance. Conventionally, droop control (as a main decentralized strategy) is been utilized in order to prevent permanent droop of voltage and frequency after change in loads and also to share generated power between distributed generation units. In this paper, a new droop control s...

Improve the Reactive Power Sharing by Uses to Modify Droop Characteristics in Autonomous Microgrids

Usually, the conventional droop methods is utilized for control of autonomous micro-grids. In islanded micro-grids (MG), due to the effects of mismatch in line impedance, the reactive power can't share by using the conventional droop method. In this paper, a method is proposed to improve reactive power sharing. In this method, the micro-sources are acted with P-w & Q-E droop characteristics, an...

A consensus-based secondary control layer for stable current sharing and voltage balancing in DC microgrids

In this paper, we propose a secondary consensus-based control layer for current sharing and voltage balancing in DC microGrids (mGs). To this purpose, we assume that Distributed Generation Units (DGUs) are equipped with decentralized primary controllers guaranteeing voltage stability. This goal can be achieved using, for instance, Plug-and-Play (PnP) regulators. We analyze the behavior of the c...

Active power sharing in microgrids

This chapter studies the problem of frequency regulation and active power sharing in inverter-based microgrids with time-varying voltages. Building upon the result in the previous chapter, we propose the design of internal-model-based controllers and analyze it within an (incrementally) passivity framework. A small case study indicates the effectiveness of the proposed solution. 3.1 A microgrid...
