With the promotion of mixed ownership reform in power enterprises and microgrid projects, the multi-subject investment stands out to avoid risk. However, it requires a scientific distribution of equity and profits. This article proposes a cooperative game based equity distribution model for the hybrid ownership companies in an integrated power and hydrogen system (IPHS). An IPHS operation model that considers the goal of smoothing wind and solar fluctuations is established. Moreover, an equity optimization model that considers creditors, government, and technology companies (TC) is established. At the level of TC architecture, three types of alliances are established: independent investment (II), partial cooperative investment (PCI), and complete cooperative investment (CCI). In the case study, the relationship between the equity and profit distribution and the project return rate is analyzed, and then optimal operation of the TC, namely distributed generation enterprises (DGE), electric and hydrogen storage enterprises (EHSE), and distribution networks (DN), is conducted. The result shows that the government needs to transfer a portion of the revenue to the TC (up to 44%) in order to ensure the minimum yield of TC before the project yield reaches 18%. What’s more, the CCI can achieve the highest operational efficiency, with equity and profit fair distribution coefficients of 0.05, 0.8, and 0.15 for DGE, EHSE, and DN, respectively.

摘要

With the promotion of mixed ownership reform in power enterprises and microgrid projects, the multi-subject investment stands out to avoid risk. However, it requires a scientific distribution of equity and profits. This article proposes a cooperative game based equity distribution model for the hybrid ownership companies in an integrated power and hydrogen system (IPHS). An IPHS operation model that considers the goal of smoothing wind and solar fluctuations is established. Moreover, an equity optimization model that considers creditors, government, and technology companies (TC) is established. At the level of TC architecture, three types of alliances are established: independent investment (II), partial cooperative investment (PCI), and complete cooperative investment (CCI). In the case study, the relationship between the equity and profit distribution and the project return rate is analyzed, and then optimal operation of the TC, namely distributed generation enterprises (DGE), electric and hydrogen storage enterprises (EHSE), and distribution networks (DN), is conducted. The result shows that the government needs to transfer a portion of the revenue to the TC (up to 44%) in order to ensure the minimum yield of TC before the project yield reaches 18%. What’s more, the CCI can achieve the highest operational efficiency, with equity and profit fair distribution coefficients of 0.05, 0.8, and 0.15 for DGE, EHSE, and DN, respectively.
