Sustainability of current energy policies and their mid-term outlooks are investigated. First, an overview is given about the trend of global energy demand and energy production. The share of energy sources and the geographic distribution of demand are analysed on the basis of the statistics and projections published by major agencies. Sustainability of selected renewable energy sources is then...

This paper focuses on the integration of hybrid renewable energy resources available in remote isolated islands of Sundarban-24 Parganas-South of Eastern part of India to National Grid of conventional power supply to give a Smart-Grid scenario. Before grid-integration, feasibility of optimization of hybrid renewable energy system is monitored through an Intelligent Controller proposed to be ins...

The introduction of photovoltaic and wind turbine generation systems has been accelerating around the world, and the case for using renewable energy remains strong. However, because of the intermittency of the renewable sources, the power generation level, or capacity factor, of these renewable energy systems is relatively low and the generation level is not fixed. Generation capacity with thes...

A photovoltaic (PV)/wind/battery/Generator-Set hybrid power system's energy dispatch is discussed in this research, along with the ideal solution. The optimization model enables generating devices to share appropriately. main goals are minimize fuel consumption and costs maximize usage of Renewable Energy Sources (RES). proposed simulation plan succeeds lowering because diesel generator only ki...

Renewable energy sources are gradually being recognized as important options in supply side planning for microgrids. This paper focuses on the optimal design, planning, sizing and operation of a hybrid, renewable energy based microgrid with the goal of minimizing the lifecycle cost, while taking into account environmental emissions. Four different cases including a diesel-only, a fully renewabl...

introduction despite the abundant renewable energy sources, the iranian energy sector relies almost entirely on fossil fuel energy resources. power sector is dominant source of co2emissions and responsible for about 35% of total co2 emissions in the country. additionally, long-term electricity demand of iran is expected to grow quickly, which in turn requires extensive investment to meet the gr...

Energy is an important fact for a country for both its socio-economic development and economic growth. Main energy source on earth is the fossil fuels. However, the usage of fossil fuels causes global warming whose negative effects have recently been felt by all over the world. Also, because it is limited on earth, increased energy demand and high energy prices increase concerns on fossil fuels...
