The demand for high quality electricity and growing electricity consumption has been caused by increasing electrification of daily life causes and the rising number of sensitive or critical loads. Due to the rapid increase in global energy consumption and the diminishing of fossil fuels, the customer demand for new generation capacities and efficient energy production, delivery and utilization ...

The growing penetration of renewable generation in distribution networks, primarily deployed by end-use electricity customers, is changing the traditional load profile and inevitably makes supply-load balancing more challenging for grid operators. Leveraging the potential flexibility of existing microgrids, that is to help with supply-load balance locally, is a viable solution to cope with this...

Smart microgrids offer a new challenging domain for power theories and compensation techniques, because they include a variety of intermittent power sources, which can have dynamic impact on power flow, voltage regulation, and distribution losses. When operating in the islanded mode, low-voltage smart microgrids can also exhibit considerable variation of amplitude and frequency of the voltage s...

This paper, proposes a control system for use with microgrid consist of multiple small scale embedded generation networks (SSEG networks) connected to the 33kV distribution network. The proposed controller controls power flow in the gridconnected mode of operation, enables voltage and frequency control when the SSEG networks are islanded, and resynchronizes the SSEG networks with the utility be...

Application of individual distributed generators can cause as many problems as it may solve. A better way to realize the emerging potential of distributed generation is to take a system approach which views generation and associated loads as a subsystem or a “microgrid”. During disturbances, the generation and corresponding loads can separate from the distribution system to isolate the microgri...

A microgrid is a part of a distribution network embedding multiple distributed generation systems (mostly nonconventional renewable energy sources like photovoltaic panels, small wind turbines etc.) and storage systems with local loads, which can be disconnected from the upstream network under emergency conditions or as planned. The microgrid concept naturally arose to cope with the penetration...

A MicroGrid can be defined as an electrical network of small modular distributed generating units (whose prime movers may be photovoltaics, fuel cells, micro turbines or small wind generators), energy storage devices and controllable loads. A MicroGrid can operate in grid-connected or islanded mode and hence increase the reliability of energy supplies by disconnecting from the grid in the case ...

 Abstract— The optimal planning problem of provisional microgrids, as a new class of microgrids, is investigated in this paper. Unlike traditional microgrids, provisional microgrids do not possess the islanding capability and are dependent on one or more electrically connected microgrids, called coupled microgrids, for islanding purposes. Provisional microgrids can be considered as enablers of...

The increasing interest in integrating intermittent renewable energy sources into microgrids presents major challenges from the viewpoints of reliable operation and control. In this paper, the major issues and challenges in microgrid control are discussed, and a review of state-of-the-art control strategies and trends is presented; a general overview of the main control principles (e.g., droop ...

Franklin E. Pacheco, James Christopher Foreman,

The purpose of this paper is to introduce a holistic and systematic approach, based in key concepts of systems thinking, systems of systems and management science; to completely represent, model and analyze microgrid systems. In this paper we propose a Microgrid Reference Methodology (MRM) that guides the cooperation and mutual benefits between electric utilities and industrial customers for mi...
