With the restructuring of power systems, increase of renewable energy sources, and as networks become smarter, power systems are facing new challenges such as uncertainty in available energy resources. An appropriate solution to address these challenges are to use energy storage systems. Therefore, sizing, location, and selection of energy storage systems are important to maximize their benefit...

This paper discusses the perspective of renewable energy (wind, solar, wave and biomass) in the making of strategies for a sustainable development. Such strategies typically involve three major technological changes: energy savings on the demand side, efficiency improvements in the energy production, and replacement of fossil fuels by various sources of renewable energy. Consequently, large-sca...

In current research, energy efficiency and technical efficiency of wheat farmers were calculated in Mazandaran province. To estimate technical efficiency the Stochastic Nonparametric Envelopment of Data (StoNED) was used. The model incorporating nonparametric data envelopment analysis model which contain the smoothness and concavity constraints with stochastic frontier analysis model. The requi...

The increase in fossil fuel prices has resulted in growing utilization of renewable energy sources in power systems. Wind energy as an economical source of energy has experienced the fastest growth among other energy sources. Traditionally, renewable energy sources as a result of their random nature have not been considered in the process of generation expansion planning. The increase in fossil...

Nowadays, with the use of devices such as fossil distributed generation and renewable energy resources and energy storage systems that are operated at the level of distribution networks, the problem of optimal reconfiguration has faced major challenges, so any change in the power of this resources can have different results in reconfiguration. Similarly, load changes during the day can lead to ...

Environmental concerns and depletion of nonrenewable resources has made great interest towards renewable energy resources. Cleanness and high potential are factors that caused fast growth of wind energy. However, the stochastic nature of wind energy makes the presence of energy storage systems (ESS) in wind integrated power systems, inevitable. Due to capability of being used in large-scale sys...

As people living in remote areas rely on SPS systems for their electricity and water needs, they hold a practical and non-idealistic perspective towards using renewable energy technologies. This research explores pastoral owner-operators’ personal experience and opinion of stand-alone power supply (SPS) systems over 30 years in remote pastoral regions Western Australia (WA). This research was u...
