A novel direct distribution method based on dynamic characteristic coefficient for combined heat and power dispatch in single extraction units

The combined heat and power (CHP) dispatch is of important to determine the optimal combination of the power and heat outputs, satisfying heat and power demand and operational constraints. This paper aims to propose a novel direct distribution method based on dynamic characteristic coefficient in single extraction units. More precisely, some dynamic characteristic equations are first established according to cycle function method; then, the optimization problem of CHP dispatch is formulated. To perform well, linear programming is implemented by comparing with our method. Experimental results suggest that our method has appropriate accuracy with sufficient benefits in guiding the operation for load dispatch in practice.
