Discussion on Operational Strategy Planning Model of Multi-Energy Complementary Distributed Energy System

Résumé fourni par la source

With the growth of industry, we are faced with the problem of energy shortage. The CCHP system can realize the advantages of different kinds of energy are complementary and the gradient utilization of energy, and effectively realize the improvement of energy efficiency. However, the capacity configuration and operation strategy of the system need to be rationally designed to maximize the usefulness of the system. In this paper, a linear programming model is constructed to achieve the optimization of the capacity and operation strategy of the CCHP system with the total annual cost as the objective function. In addition, Dual simplex-genetic algorithm two-stage optimization method (DS-GA) is proposed to analyze and discuss linear and nonlinear planning by taking a building in Xi'an, China, as an example. The results show that the simulation results of the linear model can reflect the real operation of the system to a certain extent, and the use of multiple small-capacity devices to replace a single large-capacity device in the CCHP system can reduce the constraints imposed by the load factor on the efficiency of the device, thus improving the energy efficiency of the device.
