Unit commitment in multiple energy carrier systems

During the last decade there has been a strong development of energy applications that make use of multiple energy carriers. A new approach is necessary to tackle problems related to planning and operation of energy systems, since conventional techniques are mostly oriented to deal with independent energy carrier infrastructures only. The contribution of this paper is to offer a general unit commitment framework for energy systems that contain multiple energy carriers and to present illustrative examples on the topic. The unit commitment problem is solved using the optimization software AIMMS.
