Abstract

In order to improve the utilization rate of clean energy and achieve low-carbon and economic operation of the power system, this paper constructs an optimal scheduling model of virtual power plants (VPPs) that aggregate wind power, photovoltaic power, oxygen‑enriched combustion, gas turbine, waste heat recovery and utilization system, and proton exchange membrane electrolyzer (PEMEL). Firstly, the electrolyzer, methanation, and proton exchange membrane fuel cell (PEMFC) are modeled from the perspective of waste heat recovery and utilization, considering the joint operation of electrolyzers and oxygen-enriched combustion power plants. Next, from the perspective of oxygen-enriched combustion power plants, the feasibility of achieving low-carbon and economic operation is analyzed. Taking the minimization of operating costs as the objective function, a low-carbon optimal scheduling model for the VPP is constructed. Finally, in order to verify the effectiveness and feasibility of the established model, five scenarios are set up to compare and analyze the running results of the VPP. The results show that the proposed method can effectively promote the consumption of clean energy, utilize recovered waste heat, and achieve low-carbon and economic operation of VPPs.
