With the increase in the level of global warming, renewable energy based distributed generators (DGs) will increasingly play a dominant role in electricity production. Distributed generation based on solar energy (photovoltaic and solar thermal), wind, biomass, mini-hydro along with use of fuel cells and micro turbines will gain considerable momentum in the near future. A microgrid consists of ...

Harmonics distortion is a crucial problem in microgrid. Harmonic sources can be categorized as two main factors: renewable energy integration and nonlinear loads. Both factors are investigated in this paper. For renewbale energy, photovoltaic (PV) power is one of the most effective solutions for energy crisis and it is showing great potential for serving customers in microgrid. A threephase PV ...

Development of Electrical Vehicles (EVs) has been created many challenges and also advantages for grids. One of the most important subjects is capability of which as energy storage device. In this paper, role of EVs has been studied as useful element in microgrids as energy storage device to reduce the on-peak load in microgrid and decrease the total cost of microgrid. For this goal the problem...

 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...

In an islanded DC microgrid with multiple distributed generators (DGs), the droop control is employed to realize proportional current sharing among DGs in microgrid. The action of causes a deviation bus voltage which exacerbated by line impedance between DG and bus. this paper, advanced secondary scheme proposed simultaneously achieve accurate regulation cooperative system. controller introduce...

Islanded microgrids have low inertia due to a large penetration of non-inertial inverter based power sources. In such systems, the primary frequency controller (PFC) faces issue higher rate change (RoCoF) and peak deviation in case sudden load or generation loss. The control becomes more challenging as variation different sources is not synchronized. This paper proposes model for dynamics an is...

This paper presents the dynamic modeling and simulation of a microturbine generation (MTG) system, the nonrenewable source of energy suitable for isolated as well as grid-connected operation in microgrid networks. A microgrid is defined as an independent low or mediumvoltage distribution network comprising various DGs, energy storages, and controllable loads. The MTG system consisting of a perm...

The paper considers the calculation of an effective energy schedule in an islanded microgrid. GridLab-D open source simulation tool is used for simulation of microgrid elements. Matlab environment is used to run an optimization solver. The product GridMat is used as an interface tool between Matlab and GridLab-D. An economic scheduling optimization problem for the considered microgrid is formul...

As an important part of s mart grid, microgrid(MG) is a new form of s mart grid in the future. Microgrid(MG) technology can effectively integrate the advantages of new energy and renewable energy generation and provide a novel way for large-scale applicat ions of new energy and renewable energy connecting to grid. This paper deals with the problem of economic operation of microsources in the mi...

Autonomous systems operating in real-world environments must be able to plan, schedule, and execute missions while robustly adapting to uncertainty and disturbances. Previous work on dispatchable execution increases the efficiency of plan execution under uncertainty by introducing a temporal plan dispatcher that schedules events dynamically in response to disturbances, and a compiler that reduc...
