Energy is one of the most important requirements in development of societies. In the last decade, widespread attention has been paid to renewable energies. Despite the obvious advantages of renewable energy resources, their dependence on climate change is one of the most fundamental problems facing to the development of them. Optimal design of hybrid renewable energy systems is a major issue in...

The continuous power supply for rural areas can be possible by using renewable hybrid power generation system and also reduction of the energy storage devices for the system. The impact of the shortage of power supply probability, surpluspower power generation, ratio of the energy supply to load demand, renewable fraction of different types of energy resources (solar and wind) and the combined ...

The recent trend to design more efficient and versatile ships has increased the variety in hybrid propulsion and power supply architectures. In order to improve performance with these architectures, intelligent control strategies are required, while mostly conventional control strategies are applied currently. First, this paper classifies ship propulsion topologies into mechanical, electrical a...

The traditional HVDC plays an important role in the development of power grid. But the traditional HVDC cannot supply power either to entirely passive AC network or to weak AC system. In fact, an entirely passive AC network can be effectively powered through VSC-HVDC. However, the cost of investment in VSC-HVDC is amazingly high due to the limitation of power electronics technology. Based on CS...

A hybrid thermal model for accurate estimation of thermal condition of cagerotor induction motors under non-standard supply systems has been presented. The developed thermal model is a combination of lumped and distributed thermal parameters which are available from motor dimensions and other physical constants. The thermal condition of the motor under non-standard supply systems such as unbala...

It not normally exceed 200 words.

In this paper, a supervisory controller is proposed to manage the power flow in a hybrid AC/DC micro-grid for both grid-connected and disconnected modes. When the hybrid AC/DC micro-grid is connected to the utility grid, power surplus or shortage leads to power trade between the micro-grid and the utility grid. In the grid-disconnected mode, the renewable power sources (wind and solar generatio...
