Abstract
Due to its relatively high total energy eOEciency, the application of cogeneration is attracting increased attention. Today cogeneration is an essential element in the energy supply system in many countries, and when environmental and economic aspects are considered too, it seems to be a relevant option in expansion planning in many situations. The present paper presents a quite general and yet detailed modeling of a cogeneration plant which feeds its output water into a district heating network, and which includes several possible types of energy transformation units, the central one being the cogeneration unit. The modeling also includes a heat water storage. The model cost function is nonlinear and has linear constraints. Storage losses, minimalup and down times and time depending start-up costs are considered. The time horizon is partitioned into a ønite number of discrete intervals. In this paper, the unit commitment problem in combination with the economic dispatch problem is sol...
