Energy issues and energy management gain more interest within the society at large as well as amongst companies of different sizes. Yet, even in energy-intensive companies, like process industries, energy management is seldom treated strategically. The purpose of this study is thus to...

In this paper we consider integrated planning of the supply chain at a multi-site pulp company. In addition to the traditional focus on pulp products, also energy aspects are considered, both in the form of raw material and as revenue generating products. The idea is that energy intense raw...

A multi-period mixed-integer linear programming model has been developed to help explore future pathways for electricity supply where costs and carbon reduction are a priority. The model follows a life cycle approach and can optimise on costs and on a number of environmental objectives. To...

The concept of inoperability was originally introduced as a means of quantifying risk in systems comprised of interdependent subsystems, using a modified input–output framework. This paper describes a novel robust optimization model for energy planning with inoperability constraints. The...

Traditional energy planning methods emphasize the total energy supply equaling to the total demand and neglect details of the distribution in energy demand and supply within a region or city. An improved two-step floating catchment area (2SFCA) method is developed to reflect internal...

This paper proposes a new methodology to include financial risk management in the framework of two-stage stochastic programming for energy planning under uncertainties in demand and fuel price. A deterministic mixed integer linear programming formulation is extended to a two-stage stochastic...

Energy management system (EMS) within buildings has always been one of the main approaches for an automated demand side management (DSM). These energy management systems are supposed to increase load flexibility to fit more the generation from renewable energies and micro co-generation devices....

Although electricity supply is still dominated by fossil fuels, it is expected that renewable sources will have a much larger contribution in the future due to the need to mitigate climate change. Therefore, this paper presents a new framework for developing Future Electricity Scenarios...

This paper provides a methodology to build offering curves for a concentrating solar power plant. This methodology takes into account the uncertainty in the thermal production from the solar field and the volatility of market prices. The solar plant owner is a price-taker producer that...

This paper considers a deregulated electricity market environment where a natural gas-fired generation company can engage in different types of contracts to manage its natural gas supply as well as trade on the electricity market. If the contracts are properly designed, they can protect the...
