Intelligent Distributed Generation and Storage Units for DC Microgrids - A New Concept on Cooperative Control without Communications Beyond Droop Control
TL;DR: A new decentralized strategy based on fuzzy logic that ensures stored energy balance for a low voltage dc microgrid with distributed battery energy storage systems by modifying the virtual resistances of the droop controllers in accordance with the state of charge of each energy storage unit is proposed.
Journal ArticleDOI
Mixed-Integer-Linear-Programming-Based Energy Management System for Hybrid PV-Wind-Battery Microgrids: Modeling, Design, and Experimental Verification
TL;DR: In this paper, a modular energy management system and its integration to a grid-connected battery-based microgrid is presented, where a power generation-side strategy is defined as a general mixed-integer linear programming by taking into account two stages for proper charging of the storage units.
Journal ArticleDOI
Centralized Control Architecture for Coordination of Distributed Renewable Generation and Energy Storage in Islanded AC Microgrids
TL;DR: In this paper, a centralized control architecture for local area power systems such as a small-scale microgrid is proposed, which is based on three supervisory control tasks which consider: active power curtailment of generation for avoiding overcharge of the storage units, load shedding actions for preventing deep discharge of the stored units, and equalization of the state of charge (SoC) among distributed storage systems for avoiding uneven degradation.
Journal ArticleDOI
Online Energy Management Systems for Microgrids: Experimental Validation and Assessment Framework
TL;DR: In this paper, an adaptable energy management system implemented in an online scheme, as well as an evaluation framework to quantitatively assess the enhancement attained by different online energy management strategies is presented.
Journal ArticleDOI
Cooperative energy management for a cluster of households prosumers
TL;DR: An energy management system for coordinating the operation of distributed household prosumers is proposed and it was found that better performance is achieved when cooperative operation with other prosumers in a neighborhood environment is achieved.
