A Simulation Algorithm Based on Optimal Operation Strategy for CCHP System

Abstract

The operation problem is modeled as nonlinear programming in which the relationship between generating and heating and the generating efficiency change with the power generating are considered as the constraints. The KKT condition of the optimal operation model are investigated for the typical operation strategy, and the condition that the typical operation strategy is optimal operation strategy are obtained. A CCHP simulation algorithm based on optimal operation strategy is presented in this paper. The numerical results demonstrated that the operation cost based the presented operation strategy reduces significantly comparison with the traditional operation strategy.
