The use of distributed generation in microgrid systems is becoming a popular way to provide a reliable source of electricity to critical loads. Efforts in disaster relief operations and national defense applications require a mobile, scalable power grid that is easily constructed and robust enough to handle radical system changes. These microgrids are usually built using low-inertia generators ...

This paper introduces the results of a research project whose objective is to extend obtained capabilities of a resilient microgrid to a conventional distribution network. This system has been previously sized and optimized to fully operate in an autonomous way. The presented work is an advanced interface control system for grid connection of this cluster in order to provide the over power in c...

DC loads (such as computers, data centres, electric vehicle chargers, and LED lamps) and dc distributed energy resources (such as fuel cells, solar photovoltaics, and energy storages) are rapidly growing in electric power systems, so dc systems are being introduced as emerging practical investment solutions compared to traditional ac options. DC microgrids offer several advantages such as the e...

This paper presents a microgrid planning model for determining the optimal size and the generation mix of distributed energy resources (DERs) as well as the microgrid type, i.e., AC or DC. Considering the growing ratio of DC loads and DERs, DC microgrids could be potentially more beneficial than AC microgrids by avoiding the need to synchronize generators, reducing the use of converters, facili...

The paper outlines the design considerations for electrical microgrid Power Management Model (PMM). Design considerations for decentralized power management control for a microgrid that operates in an isolated mode disconnected from the main power grid is the main focus. An example based in part on a hypothetical scenario of the transformation process of the No Name Key Island, an island in the...

The use of an electrical energy storage system (EESS) in a microgrid (MG) is widely recognized as feasible method for mitigating the unpredictability and stochastic nature sustainable distributed generators other intermittent sources. battery (BES) most effective several power methods available today. unit commitment (UC) determines number dedicated dispatchable generators, respective power, am...

In this paper, a distributed generation including diesel generators, wind turbines, and microturbines are introduced, and their mathematical model is described using the Taylor expansion method. With the goal of computational complexity eliminating, the reduced order model (ROM) of microgrid components is considered. The results of the ‌‌studies indicate that the microgrid frequency is unstable...

In this paper, the concept of secondary control is applied for voltage unbalance compensation in an islanded microgrid. The aim of the proposed control approach is to enhance the voltage quality at the point of common coupling (PCC). Unbalance compensation is achieved by proper control of distributed generators (DGs). The DGs control structure mainly consists of active and reactive power contro...

GreenHouse Gasses’ (GHG) emission control is the greatest environmental challenge facing the world. The energy sector accounts for the highest percentage of environmental pollution. Emissions from internal combustion power generators are high and these emissions are responsible for the fast depletion of the ozone layer. Though there are other measures put in place to control the emission from p...
