Abstract
Traditional distributed generation (DG) planning often only considers a single stakeholder and does not take into account demand response, which fails to take into account the interests of various stakeholders in the market and ignores the regulation capabilities of load and energy storage. Aiming at the above problems, this article proposes an optimal distributed power allocation model that takes into account the interests of distributed power operators, distribution companies and power users, as well as the demand response. Carbon trading mechanism and green certificate trading mechanism are introduced to take into account the carbon emissions during power generation and transmission and the flexibility resources on the energy storage side to establish a multi-principal allocation model that considers the environmental cost of carbon emissions and demand response; the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) comprehensive evaluation idea to maximise the benefits of each subject, and adopt the second-order cone relaxation technique for planning solution. The case analysis results show that the proposed optimal allocation model can effectively balance and improve the income of each subject. Compared with the traditional model, which does not consider energy storage and only maximizes the benefits of DG operators, the comprehensive benefits are improved by 43.7 %, and the consumption capacity of distributed generation is improved. It promotes carbon emission reduction and reduces carbon emissions by 1,243.05 t, which verifies the effectiveness of the proposed model.
