Optimization of a combined heat and power system with wind turbines

In this paper, an optimization model is developed for a system consisting of both combined heat and power units and wind turbines. The analysis is conducted in the scope of economic dispatch. In the present model, the probability (rather than the average) of stochastic wind power is considered as a constraint. This approach avoids the probabilistic infeasibility appearing in conventional approaches. It is shown that the effects of wind speed on the generated power and heat can be readily assessed in terms of reliability. (C) 2012 Elsevier Ltd. All rights reserved.
