The use of renewable energy sources (RESs) is a need global society. This editorial, and its associated Special Issue “Grid-Connected Renewable Energy Sources”, offer compilation some the recent advances in analysis current power systems composed after high penetration distributed generation (DG) with different RESs. focus on both new control configurations novel methodologies for optimal place...

Island electricity systems tend to rely heavily on the use of fossil fuels for the everyday supply of customer needs, so there are both significant economic and environmental benefits from the decarbonisation of these systems. One such key global environmental benefit is the anticipated reduction in CO2 emissions and its associated effects on climate change. In recognition, many islands are alr...

Recent year’s renewable energy sources plays important role in power generation system. Due to intermittent nature of renewable sources such as wind and solar, the energy storage systems (ESS) are required in renewable power generating systems. This paper deals with power management of the ESS based on hydrogen storage (electrolyzer, hydrogen tank, fuel cell) and battery integrated in hybrid re...

Renewable energy has had a steady and continuous growth in electric sector worldwide. The need of the hour is to sensitize the general public about the importance of judicious use of energy being generated by conventional sources energy sources and simultaneously shift our dependence on renewable but sustainable energy sources. To mitigate environmental degradation and reduce carbon emission wo...

-Many sources of renewable energy, including solar, wind, and ocean wave, offer significant advantages such as no fuel costs and no emissions from generation. However, in most cases these renewable power sources are variable and nondispatchable. The utility grid is already able to accommodate the variability of the load and some additional variability introduced by sources such as wind. However...

Renewable Energy based microgrids are being considered to provide electricity for the expanding energy demand in the grid distribution network and grid isolated areas. The technical challenges associated with the operation and controls are immense. Electricity generation by Renewable Energy Sources is of stochastic nature such that there is a demand for regulation of voltage output in order to ...

There is an ongoing debate among energy experts on how providing a subsidy for one energy source affects the investment in other sources. To explore this issue, we study capacity investments of a utility firm in renewable and conventional sources. Specifically, conventional sources are categorized into two groups as inflexible (e.g., nuclear and coal-fired plants) and flexible (e.g., natural ga...

Renewable electricity generation systems are increasingly used as a means of reducing harmful emissions and also reducing operational costs, by comparison with the use of fossil fuels. However, renewable energy sources such as solar energy are characterised by a high degree of intermittence, sometimes unpredictable. This constraint leads to inability to meet the demand of a power system. Hybrid...

We develop a spatial model of energy exploitation where energy sources are differentiated by their geographic location and energy density. The spatial setting creates a scaling law that magnifies the importance of differences across energy sources. As a result, renewable sources twice as dense, provide eight times the supply; and all new non-renewable resource plays must first boom and then bus...
