The microgrid (MG) concept is attracting considerable attention as a solution to energy deficiencies, especially in remote areas, but the intermittent nature of renewable sources and varying loads cause many control problems and thereby affect the quality of power within a microgrid operating in standalone mode. This might cause large frequency and voltage deviations in the system due to unpred...

One of the main actions required to face and limit global warming is substitution conventional fossil-fueled electrical generators with renewable ones. Thus, it becomes fundamental create non-dispatchable able provide services for power system stabilization that nowadays are delivered by Particularly, usually connected through electronic converters lacking natural responses frequency variations...

variation of frequency and voltage by load changes in a microgrid is a challenge in droop control method. centralized restoration frequency or voltage in a microgrid requires communication link and therefore affects the advantage of decentralized droop control such as reliability, simplicity and inexpensiveness. this paper proposes a decentralized method that restores the frequency of a microgr...

Reliance on imported diesel fuel, with high transportation costs, has made power and water treatment expensive in remote microgrids the Arctic. Past attempts at implementing piped these areas have proven difficult due to cost of energy pump, transport, heat fuel. A modular Water Reuse (WR) system been developed provide more affordable, distributed service for an individual home lacking running ...

This paper suggests an approach of synchronized and incorporated management of solar power PV generators with the maximum power point tracking (MPPT) management and battery power storage space management to offer 1)voltage and frequency (V-F) support to an islanded microgrid 2) real and reactive power (P-Q) support during grid connection. The present novel control strategy show the the effectiv...

Large commercial and industrial loads known as large energy consumers are always seeking to reduce their energy costs and consequently they are utilizing renewable and non-renewable energy sources in procurement of their required energy. Use of renewable energy sources (RESs) and plug-in electric vehicles (PHEVs) parking lot without proper planning will make technical and economic problems for ...

This paper presents a new multilevel converter solution with modular structure and hybrid energy-storage integration suitable to drive modern/future high-power medium-voltage wind turbines. The means that part of the submodules are built batteries them conventional capacitors. Since traditional turbines non-dispatchable generators, an energy storage system could be beneficial in multiple ways a...

This paper proposes a distributed predictive secondary control strategy to share imbalance in three-phase, three-wire isolated AC Microgrids. The is based on novel approach where the sharing among generators controlled through of single-phase reactive power. main characteristic proposed methodology inclusion an objective function and dynamic models as constraints formulation. controller relies ...

Abstract—Appropriate control of high penetration renewable energies in power systems requires a complete modeling of the system. In this paper, a comprehensive state space modeling of voltage source inverters, networks and loads are studied. We have modeled a secondary voltage control that utilizes the nominal set points of the output voltage as the input for the controller design. A distribute...
