【 摘 要 】

In the face of global warming, reducing carbon dioxide emissions has become a common concern. Integrated energy system (IES) is considered to be a supporting technology to increase the proportion of clean energy use and achieve goals of carbon emission reduction and carbon neutrality. By introducing carbon neutral costs and demand response into scheduling strategy, the carbon emission and the economy of IES system operation is optimized in the proposed optimal scheduling. First, modeling of the demand response considering the transferable load and replaceable load, as well as reducible load, is established for guiding users to change their energy consumption ways. Then Structure and components of IES are discussed. Later, the article presents the IES carbon emissions calculation method and model of carbon neutrality cost. Finally, the day ahead optimal scheduling of the IES considering the demand response (DR) and carbon neutrality cost is proposed. The results show that the proposed model is effective in balancing low carbon and economy. Comparative results of different carbon neutralization adjustment coefficients shows that total operating cost as well as carbon emissions is reduced with increasing clean energy penetration and setting moderate carbon neutralization cost coefficients. By adjusting the participation of clean energy, the system cost can be effectively reduced by 48.6%. By adjusting the carbon neutralization cost coefficients, the overall carbon emission can be reduced by 282 kg.
