Clean energy for power generation and heating is an important route for clean energy consumption in the northern regions with abundant wind and solar resources. However, in the promotion of clean heating projects, there are problems such as high investment costs and high pressure from government financial subsidies. Therefore, it is urgent to explore new economically feasible business models suitable for clean energy power generation and heating. This paper first proposes a new business model of clean energy power generation and heating under the BOO operation mode of the PPP business model. Secondly, from the perspective of investment value, the net present value method is used to analyze the economic benefits of the project, and the cash flow of the clean energy power generation and heating project is analyzed. Finally, combined with actual cases in a certain area in Xinjiang, the net present value method is used to analyze the calculation examples, verify the economic feasibility of the proposed business model, and provide guidance for the further promotion of clean energy power generation and heating projects.

The rapid development of integrated wind power bring serious challenges to power system operation. In order to address the increasing wind power curtailment problem, the frequency-voltage characteristics concerned optimal dispatch for power system with large-scale wind power integration is proposed in this paper. Through integration of the optimization of frequency characteristics and voltage characteristics into the traditional power system economic dispatch model, the flexibility resources of generation side and load sides in power systems are mobilized to promote large-scale wind power accommodation. The formulated frequency-voltage characteristics concerned optimal dispatch mathematical model is a nonlinear programming model, which is solved by the GAMS platform. The numerical analysis for an actual provincial power grid indicates that the proposed frequency-voltage characteristics concerned optimal dispatch method can promote wind power utilization efficiency and improve the economy of power system operation.
