Optimal operation of industrial CHP-based power systems in liberalized energy markets

This paper presents the implementation of a new method in calculating the optimal unit commitment and economic dispatch of industrial enterprises with its own energy supply system, mostly with CHP-plants. To yield the most synergetic effects, both the marketplace and the demand of disposable industrial processes are taken into account. Because of the complexity of the formulated mathematical model and, thus, of the optimization problem, a new dynamic search strategy (DSS) based on mixed integer linear programming (MILP) is presented. With DSS, a considerable acceleration of calculation time could be achieved.
