Abstract: In the operation of traditional energy systems, part of the energy generated during the electricity production process is discarded as waste heat, resulting in energy wasted. In view of this, this dissertation proposes the use of cogeneration to integrate energy resources to achieve a higher energy efficiency. Based on cogeneration, it introduces price-based demand response (PBDR) to participate in power generation dispatching, and establishes an economic scheduling model considering the day-ahead electricity price. The model is then used to analyze the cogeneration system model which considers the demand response for the IEEE 33-bus system. Then, the YALMIP toolbox for MATLAB is used to solve the model. Simulation results show that the proposed model can effectively integrate energy resources and improve the economic benefits and stability of system operation. Apart from that, it is shown in the results that the demand load curve becomes flatter than before after implementing the PBDR strategy, and the load from the peak period can be shifted to the valley period, which markedly enhances the safety and reliability of the whole system.
