Economic Operation Research of CCHP System Based on Interior Point Method
For a combined cooling heating and power (CCHP) system which mainly consists of internal combustion engine and absorption chiller-heater,an economic operation optimization model used for the grid-connected operation mode without power injection is proposed in this paper.The coordination problem between the CCHP and the electric air conditioners is considered in the model.The minimal operation cost of the system meeting the load demand of cooling,heating and power is taken as the optimizing function.The constraints are established based on the analysis of the thermoelectric property of relevant equipment and the corresponding characteristic functions.The path tracking interior point method is used to solve the optimization problem to obtain the optimal operation scheme of the CCHP system.In the case study,a building in Guizhou province was selected as the research subject.According to the load forecasting data of cooling,heating and power of typical months of the building,the proposed optimization method based on the interior point method was applied to gain the generation schemes of the internal combustion engine and operation programs of the electric air conditioners.The results verify the feasibility of the proposed optimization method for economic operation of the CCHP system.
