Joint planning of combined heat and power and electric power systems: An efficient model formulation

The growing importance of combined heat and power (CHP) around the world has increased the need to consider its role within electric power systems. In this paper, we show how the problem of joint planning of CHP and electric power systems may be formulated more efficiently than has previously been done, by exploiting the special structure of the optimal solution. Numerical tests indicate that this reformulation typically allows a reduction in the time required for problem solution by a factor of two to five.
