Online Decentralized and Cooperative Dispatch for Multi-Microgrids

IEEE Transactions on Automation Science and Engineering, 2020
Microgrid usually associated with distributed renewable energy sources plays a key role in reducing the requirement of traditional power sources and the emission of CO2. Connecting multiple microgrids to the electric power grid can facilitate a more powerful and reliable operation. Microgrids need decentralized dispatch with the requirement of security

State estimation in Multi‐Microgrids

European Transactions on Electrical Power, 2011
AbstractIn this paper, a Multi‐Microgrid state estimator is proposed, following the concept of distribution state estimators, where a limited number of real‐time measurements are available. Since state estimation (SE) solution is impossible with these limited measurements, forecasted values of load injections at buses remote from the substations are ...

A flexible protection scheme for an islanded Multi-Microgrid

IEEE PES ISGT Europe 2013, 2013
Multi-Microgrids (MMGs) have been proposed to connect distributed generators (DG), microgrids (MG), and medium-voltage (MV) loads with the distribution system. A flexible protection scheme that enables an islanded MMG to continue operation during fault conditions is yet to be developed.

MAS for automated black start of multi-microgrids

2017 IEEE International Conference on Smart Grid Communications (SmartGridComm), 2017
Current methods for performing microgrid black start require a series of steps to be performed where loads are connected and disconnected, making a fully-automated procedure unfeasible. This paper presents a novel method to perform a microgrid black start in a single step, enabling the procedure to be automatically carried out.

Advanced control and management functionalities for multi‐microgrids

European Transactions on Electrical Power, 2011
AbstractThis paper addresses the extension of the microgrid concept, following a massive integration of these active cells in power distribution networks, by adopting a coordinated management strategy together with distributed generation units directly connected to the medium voltage distribution network.

Fault analysis of an islanded Multi-microgrid

2012 IEEE Power and Energy Society General Meeting, 2012
A microgrid (MG) is one way of integrating several low capacity renewable energy sources with a distribution grid. Multi-microgrids (MMG) originally proposed by the EU More Microgrids project can combine several MGs along with other distributed generation (DG) sources into the distribution grid.

Multi-microgrid control systems (MMCS)

IEEE PES General Meeting, 2010
The objective of this paper is to present a new concept related to the revitalized microgrid concept and the paradigm of the smart grid. A combination of a rapidly aging North American power infrastructure, a clear trend towards distributed generation, and an emphasis on electrical reliability has spurred a shift toward a more distributed ...

Analysis on the organization and Development of multi-microgrids

Renewable and Sustainable Energy Reviews, 2018
Abstract With the microgrids large-scale interconnect to the power grid, a number of neighboring microgrids in a certain region will form a multi-microgrids (MMGs) system. In the development from microgrid to smart grid, the MMGs will be a new research hotspot after microgrid.

A Hierarchical Control Strategy of Multi-Microgrids

Applied Mechanics and Materials, 2015
This paper gives a hierarchical control strategy of multi-microgrids. The hierarchical control structure is made up with microgrid center controller (MGCC), microgrid controller (MC), generator controller (GC), load controller (LC). Controllers recognize the current operation mode of microgrids according to state trigger event and local operation state,
