Business Impact and Policy on the Major Players in the Market of the Development of Distributed Energy in China

As an effective measure for the promotion of the adjustment of China’s energy structure, distributed energy and its reasonable planning and development will have a significant impact on the major players in China’s power market. With the increasing access to distributed energy, its beneficial impact on the major players in the power market will become increasingly obvious. This paper examines the influence of access to distributed energy on the development of the major players in the power market, especially power supply enterprises. On this basis, a model for the calculation of the profits and losses of distributed energy users and power supply enterprises has been established, and the specific impact on the profits of power supply enterprises after access to distributed energy becomes available can be measured. In addition, this paper puts forward related policy suggestions to be implemented after access to distributed energy becomes available based on the results of the aforementioned measurement, in order to guarantee a reasonable profit for the major players in the power market during the process of the development of distributed energy and to promote the healthy and orderly development of distributed energy.

Research on Cost-sharing Mechanism of Frequency-modulated Auxiliary Service in Different Regions Based on Analytic Hierarchy Process

As the market environment is different, the same frequency modulation (FM) auxiliary service cost sharing mechanism is not applicable to all regions, and the appropriate cost allocation method should be chosen to undertake the cost of FM auxiliary services. According to the product characteristics of FM auxiliary services, several feasible cost transmission paths are designed. By using the analytic hierarchy process (AHP), the most suitable cost transmission path is obtained.

The Power Purchase Optimization Model in China considering the Renewable Energy Risks under Different Risk Preferences

To achieve the strategic target of energy conservation and emission reduction, China is vigorously developing its large-scale and distributed renewable energy power generation industry, dominated by wind power and photovoltaic power generation. In the new situation of renewable energy power interconnection, the grid company in China must fully consider the risks caused by renewable energy when making power purchase optimization decisions. This paper sets up a power purchasing model considering the risks of the renewable energy power interconnection and testifies to the effectiveness of the model through a case study. On this basis, this paper puts forward several reasonable suggestions to help the grid company make power purchase decisions under different risk preferences.
