Urbanization itself accounts for a vast amount of energy and cities are centres of resource consumption and buildings can account for 40-60% of the urban energy usage which mostly relies on high Green-House-Gas (GHG) emitting fossil fuels. Climate change and other environmental concerns drive the policy initiatives to be renewable energy oriented. Increasing the share of renewable sources in th...

    Project scheduling   Net present value   We consider a project scheduling problem with permitted tardiness and discrete time/resource trade-offs under maximum net present value objective. In this problem, a project consists of a set of sequential phases such that each phase contains one or more sub-projects including activities interrelated by finish-start-type precedence relations with a t...

The use of renewable energy in power generation and sudden changes in load and fault in power transmission lines  may cause a voltage drop in the system and challenge the reliability of the system. One way to compensate the changing nature of renewable energies in the short term without the need to disconnect loads or turn on other plants, is the use of renewable energy storage. The use of ener...

Hybrid renewable energy systems (HRES) have been introduced to overcome intermittent nature of single-source renewable energy generation. In order to utilize HRES optimally, two issues must be considered: optimal sizing and optimal operation. The first issue has been considered vastly in several articles but the second one needs more attention and work. The performance of hybrid renewable energ...

Bioregenerative life support technologies for space application are advantageous if they can be constructed using locally available materials, and rely on renewable energy resources, lessening the need for launch and resupply of materials. These same characteristics are desirable in the global Earth environment because such technologies are more affordable by developing countries, and are more ...

India is the seventh largest country in the world, blessed with adequate solar radiation, therefore to setting up a Photovoltaic power plant is a lucrative option. In actual field conditions the performance of the PV modules vary significantly from its Standard Test Condition (STC) due to large change in environmental conditions. It is very important to study the exact meteorological parameters...
