چکیده
We present a general framework for the control of direct current (DC) microgrid with star topology (a common DC bus) consisting renewable sources energy, loads, and storage devices connected via step-up step-down DC/DC converters. The objective is guaranteeing voltage stability in while delivering power to loads extracting energy efficiently from sources. To verify grid regulation among number sharing, we use Lyapunov-based Input-to-State Stability (ISS) analysis. consider three scenarios: distributed, partially decentralized according amount information available controllers.

A Robust Consensus Algorithm for Current Sharing and Voltage Regulation in DC Microgrids
In this paper a novel distributed control algorithm for current sharing and voltage regulation in Direct Current (DC) microgrids is proposed. The DC microgrid is composed of several Distributed Generation units (DGus), interfaced with Buck converters, and current loads. The considered model permits an arbitrary network topology and is affected by unknown load demand and modelling uncertainties....
متن کاملA 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...
متن کاملBIC based on Modified Droop Control of Hybrid AC/DC Microgrid with PV/Wind/ESS under Variable Generation and Load Conditions
The idea of a microgrid is created by utilizing more diverse ac or dc distributed generation (DG) sources along with an energy storage system (ESS) and loads. The most efficient and reliable selection of ac and dc microgrids is a hybrid ac/dc microgrid. The hybrid microgrid largely overcomes the shortcomings of standalone ac or dc microgrids. A bidirectional interlinking converter (BIC) is util...
متن کاملModeling, Control and Protection of Low-Voltage DC Microgrids
Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. AC/DC conversion is instead centralized, and by using efficient, fully controllable power-electronic interfaces, high ...
متن کاملA New Approach for Voltage Balancing and Appropriate Power-Sharing in Autonomous Microgrids
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 algorith...
