This paper proposes an adaptive real-time energy scheduling method (RT-EMS) for a microgrid, using Lyapunov optimization-based approach. Inaccuracy in day-ahead predictions can result non-optimal solutions to the problem. Although optimization eliminates need deal with prediction uncertainties, it ignores valuable statistical information used stochastic approaches and provides suboptimal The pr...

Electric Vehicles (EVs) will be a key component of sustainable e-transportation systems. It is important to provide charging infrastructure for EVs. EVs are “zero” polluting and highly efficient, but these qualities valid only if the EV supplied from renewable energy sources (RES). In urban areas, there lot unused space such as roofs residential enterprise buildings, parking lots, building faca...

With the rapid development of wind turbine, photovoltaic and battery technologies, renewable energy resources such as wind and solar become the most common distributed generations (DG) that are being integrated into microgrids. One key impediment is to determine the sizes and placements of DGs within which the microgrid can achieve its maximum potential benefits. The objective of the paper is t...

To implement renewable energy resources, microgrid systems have been adopted and developed into the technology of choice to assure mass electrification in the next decade. Microgrid systems have a number of advantages over the conventional utility grid systems, however, it faces severe instability issues due to continually increasing constant power loads. To improve the stability of the entire ...

Renewable and non-conventional distributed energy resources (DERs), such as, wind, solar PV, micro-turbines, fuel cells, diesel generators etc. are gradually becoming more popular as energy efficient and low-emission energy sources. Demand-side management, along with the integration of distributed energy generation and storage, are considered increasingly essential elements for implementing the...

Several drivers, usually recognized as electricity market, renewable energy sources and smartgrids are behind the concept of increasing distributed electricity generation from solar PV systems, wind turbines and CHP systems. These microsources have been installed as a consequence of government incentives aiming to secure supply of energy and to reduce the CO2 emissions by using renewable energy...

The microgrids are composed of small scale fueled generation capacities, renewable energy sources, storage energy systems, controllable loads, and autonomously can connect or disconnect from the mains supply. The microgrids can operate connected to the upstream main grid, or in an islanded operation mode following a large perturbation in the upstream grid. The microgrid analyzed in this paper i...

An important task of power demand and supply management in microgrids is to maintain a good match between power generation and consumption at the minimum cost. Since the highly fluctuant renewable energies constitute a significant portion of the power resources in microgrids, the microgrid system central controller (MGCC) faces the challenge of effectively utilizing the renewable energies while...
