We present a family of resource constraints which allow us to model scheduling problems with time variable resource cost. Our main use case is energy cost minimization, by avoiding peak electricity usage periods in the generated schedule. This at the same time helps to balance the overall demand profile, leading to reduced stress on the national electricity grid. The proposed constraints extend...

In a carbon-constrained world, natural gas with low emission intensity plays an important role in the energy consumption area. Energy consumers and distribution networks are linked via energy hubs. Meanwhile, reconfiguration that optimizes operational performance while maintaining a radial network topology is a worldwide technique in the electricity distribution system. To improve the overall e...

nowadays, electricity is one of the most significant infrastructures required for economic development of countries. hence, predicting electricity demand is very important especially in industry as a major electricity-consuming sector. the majority of studies under the subject of electricity demand have been performed by econometrics and it is not possible to investigate the effect of different...

Electricity transmission has become the pivotal industry segment for electricity restructuring. Yet, little is known about the shape of transmission cost functions. Reasons for this can be a lack of consensus about the definition of transmission output and the complexitity of the relationship between optimal grid expansion and output expansion. Knowledge of transmission cost functions could hel...

Approximately 2.4 million tons of bagasse are produced each year in Iran, most of which are currently treated as waste adding to serious environmental concerns. Application of bagasse for energy production is a sustainable solution to supply the required energy within the sugar refineries and export the surplus electricity to the grid. Currently, the energy demand in Iranian sugar mills is main...

This study investigates the energy and cost performance of hybrid renewable ground source heat pump (GSHP) and natural gas fueled fuel cell (FC) microgeneration systems serving multiple residential and small office buildings in Ottawa (Canada) and Incheon (South Korea). The study is performed by simulations in TRNSYS environment. The performance of the microgeneration system is compared to a GS...

The electricity market, monopolistic in nature, with government price regulation, poses a serious challenge for policy makers with respect to the cost-effectiveness of emissions trading, particularly in Asian countries. This paper argues that a cap-and-trade regulatory system for indirect emissions combined with a rate-based allocation system for direct emissions can achieve market efficiency e...

The necessary electricity of the workshops and buildings (W&Bs;) located at the metro depot are provided by lighting power substation (LPS). To transmit electricity between LPS and W&Bs;, some trenches should be dig and the requisite cables should be located in the trenches. This paper presents a new mixed integer linear programming (MILP) long-term decision model to find ...
