In this paper, we propose a framework for optimal energy scheduling combined with a transaction mechanism to enable multiple microgrids to exchange their energy surplus/deficit with others while the distributed networks of microgrids remain secure. Our framework is based on two layers: a distributed network layer and a market layer. In the distributed network layer, we first solve optimal power...

Ship microgrids have recently received increased attention, mainly due to the extensive use of power electronically interfaced loads and sources. Characteristics of these microgrids are similar to islanded terrestrial microgrids, except the presence of highly dynamic large loads, such as propulsion loads. The presence of such loads and sources with power-electronic converter interfaces lead to ...

Public low voltage feeders containing a mixture of several micro-sources, distributed energy storage units (ESUs) and controllable loads, which appear to the upstream distribution network as controllable entities, are known as MicroGrids. Through intelligent co-ordination of micro-generators and ESUs, coupled with demand side management techniques, MicroGrids have the potential to offer signifi...

Power networks with multiple microgrids require flexibility and versatil-ity in their coordination tools and decision-making tools from both technical and economical points of view. In particular, the microgrids involve a high penetration of variable energy resources which motivates the need for new coordination and control approaches. In this chapter, some of the literature gaps with respect t...

Microgrids can be considered as controllable units from the utility point of view because the entities of microgrids such as distributed energy resources and controllable loads can effectively control the amount of power consumption or generation. Therefore, microgrids can make various contracts with utility companies such as demand response program or ancillary services. Another advantage of m...

In this paper, the major challenges and issues in control of microgrids are discussed. The paper classifies possible microgrid control architectures from highly centralized to fully distributed peer-to-peer techniques. A control paradigm based on coupled microgrids, peer-to-peer communication and autonomous control, is proposed as a way to control the distribution network with a high penetratio...

This paper explores the structure, use, and value of Distributed Grid Management as a process and technology to support distributed grid optimization functions and microgrids to better integrate into the electrical grid small quantities of local, distributed power generated from renewable resources. The paper describes the value of distributed distribution management as it applies to Microgrids...

Smart grid has integrated an increasing number of distributed energy resources to improve efficiency and flexibility of power generation and consumption as well as the resilience of the power grid. The energy consumers on the power grid (e.g., households) equipped with distributed energy resources can be considered as “microgrids” that both generate and consume electricity. To facilitate energy...

Abstract: Interest in DC microgrids is rapidly increasing along with the improvement of DC power technology because of its advantages. To support the integration process of DC microgrids with the existing AC utility grids, the form of hybrid AC/DC microgrids is considered for higher power conversion efficiency, lower component cost and better power quality. In the system, AC and DC portions are...

This paper proposes a distributed algorithm for online energy management in networked microgrids with a high penetration of distributed energy resources (DERs). The implementation of networked microgrids with high penetration of DERs brings power generation closer to electricity users, which has advantages of increasing power supply efficiency and reliability by shortening the power supply deli...
