Optimal Planning of Integrated Electricity and Natural Gas System Based on C&CG Algorithm

Abstract

In order to improve energy efficiency and solve environmental pollution problems, integrated electricity and natural gas (IENG) system has become the first choice. It is of great significance to study the coupling mode, planning and operation of IENG. In this paper, according to the uncertainties of load and renewable energy, a robust optimization method is adopted. IENG system considering power to gas (PtG) and gas turbine (GT) is modeled. On this basis, an optimal planning model is proposed, and the C&CG algorithm is used to solve the problem. A case study illustrates the influence of different conditions on the optimal planning results, and the operation results are also analyzed.
